The giraffe is a large African hoofed mammal belonging to the genus Giraffa. It is the tallest living terrestrial animal and the largest ruminant on Earth. Traditionally, giraffes were thought to be one species, Giraffa camelopardalis, with nine subspecies. Most recently, researchers proposed dividing them into up to eight extant species due to new research into their mitochondrial and nuclear DNA, as well as morphological measurements. Seven other extinct species of Giraffa are known from the fossil record. The giraffe's chief distinguishing characteristics are its extremely long neck and legs, its horn-like ossicones, and its spotted coat patterns. It is classified under the family Giraffidae, along with its closest extant relative, the okapi. Its scattered range extends from Chad in the north to South Africa in the south, and from Niger in the west to Somalia in the east. Giraffes usually inhabit savannahs and woodlands. Their food source is leaves, fruits, and flowers of woody plants, primarily acacia species, which they browse at heights most other herbivores cannot reach. (Source: Wikipedia.org, CC BY-SA)
Wildebeest (/ˈwɪldɪbiːst/ WIL-dib-eest, /ˈvɪl-/ VIL-, /-dəb-/), also called gnu (/njuː/ NEW or /nuː/ NOO), are antelopes of the genus Connochaetes and native to Eastern and Southern Africa. They belong to the family Bovidae, which includes true antelopes, cattle, goats, sheep, and other even-toed horned ungulates. There are two species of wildebeest: the black wildebeest or white-tailed gnu (C. gnou), and the blue wildebeest or brindled gnu (C. taurinus). Fossil records suggest these two species diverged about one million years ago, resulting in a northern and a southern species. The blue wildebeest remained in its original range and changed very little from the ancestral species, while the black wildebeest changed more as adaptation to its open grassland habitat in the south. The most obvious ways of telling the two species apart are the differences in their colouring and in the way their horns are oriented. (Source: Wikipedia.org, CC BY-SA)
The goat or domestic goat (Capra hircus) is a domesticated species of goat-antelope typically kept as livestock. It was domesticated from the wild goat (C. aegagrus) of Southwest Asia and Eastern Europe. The goat is a member of the animal family Bovidae and the tribe Caprini, meaning it is closely related to the sheep. There are over 300 distinct breeds of goat. It is one of the oldest domesticated species of animal, according to archaeological evidence that its earliest domestication occurred in Iran at 10,000 calibrated calendar years ago. Goat-herding is an ancient tradition that is still important in places such as Egypt. Goats have been used for milk, meat, fur, and skins across much of the world. Milk from goats is often turned into goat cheese. Female goats are referred to as does or nannies, intact males are called bucks or billies, and juvenile goats of both sexes are called kids. Castrated males are called wethers. While the words hircine and caprine both refer to anything having a goat-like quality, hircine is used most often to emphasize the distinct smell of domestic goats. (Source: Wikipedia.org, CC BY-SA)
The European goldfinch or simply the goldfinch (Carduelis carduelis) is a small passerine bird in the finch family that is native to Europe, North Africa and western and central Asia. It has been introduced to other areas, including Australia, New Zealand and Uruguay. The breeding male has a red face with black markings around the eyes, and a black-and-white head. The back and flanks are buff or chestnut brown. The black wings have a broad yellow bar. The tail is black and the rump is white. Males and females are very similar, but females have a slightly smaller red area on the face. The average European goldfinch is 12–13 cm (4.7–5.1 in) long with a wingspan of 21–25 cm (8.3–9.8 in) and a weight of 14 to 19 g (0.49 to 0.67 oz). The sexes are broadly similar, with a red face, black and white head, warm brown upper parts, white underparts with buff flanks and breast patches, and black and yellow wings.

A goose (pl: geese) is a bird of any of several waterfowl species in the family Anatidae. This group comprises the genera Anser (the grey geese and white geese) and Branta (the black geese). Some other birds, mostly related to the shelducks, have 'goose' as part of their names. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are smaller. Geese like the Canada goose do not always migrate. Some members of the species only move south enough to ensure a supply of food and water. When European settlers came to America, the birds were seen as easy prey and were almost wiped out of the population. The species was reintroduced across the northern U.S. range and their population has been growing ever since. (Source: Wikipedia.org, CC BY-SA)
Gorillas are herbivorous, predominantly ground-dwelling great apes that inhabit the tropical forests of equatorial Africa. The genus Gorilla is divided into two species: the eastern gorilla and the western gorilla, and either four or five subspecies. The DNA of gorillas is highly similar to that of humans, from 95 to 99% depending on what is included, and they are the next closest living relatives to humans after chimpanzees and bonobos. Gorillas are the largest living primates, reaching heights between 1.25 and 1.8 metres, weights between 100 and 270 kg, and arm spans up to 2.6 metres, depending on species and sex. They tend to live in troops, with the leader being called a silverback. The Eastern gorilla is distinguished from the Western by darker fur colour and some other minor morphological differences. Gorillas tend to live 35–40 years in the wild. The oldest gorilla known is Fatou (b. 1957), who is still alive at the advanced age of 65 years. (Source: Wikipedia.org, CC BY-SA)
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are among what is possibly the most ancient living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. Grasshoppers are typically ground-dwelling insects with powerful hind legs which allow them to escape from threats by leaping vigorously. As hemimetabolous insects, they do not undergo complete metamorphosis; they hatch from an egg into a nymph or 'hopper' which undergoes five moults, becoming more similar to the adult insect at each developmental stage. The grasshopper hears through the tympanal organ which can be found in the first segment of the abdomen attached to the thorax; while its sense of vision is in the compound eyes, the change in light intensity is perceived in the simple eyes (ocelli). At high population densities and under certain environmental conditions, some grasshopper species can change color and behavior and form swarms. Under these circumstances, they are known as locusts.

The greater kudu (Tragelaphus strepsiceros) is a woodland antelope found throughout eastern and southern Africa. Despite occupying such widespread territory, they are sparsely populated in most areas due to declining habitat, deforestation, and poaching. The greater kudu is one of two species commonly known as kudu, the other being the lesser kudu, T. imberbis. Greater kudus have a narrow body with long legs, and their coats can range from brown/bluish grey to reddish brown. They possess between 4 and 12 vertical white stripes along their torso. The head tends to be darker in colour than the rest of the body, and exhibits a small white chevron which runs between the eyes. Greater kudu bulls tend to be much larger than the cows, and vocalize much more, utilizing low grunts, clucks, humming, and gasping. The bulls also have beards running along their throats, and large horns with two and a half twists, which, were they to be straightened, would reach an average length of 120 cm (47 in), with the record being 187.64 cm (73.87 in). They diverge slightly as they slant back from the head. The horns do not begin to grow until the bull is between the ages of 6–12 months. The horns form the first spiral rotation at around 2 years of age, and not reaching the full two and a half rotations until they are 6 years old; occasionally they may even have 3 full turns.

The green heron (Butorides virescens) is a small heron of North and Central America. Butorides is from Middle English butor 'bittern' and Ancient Greek -oides, 'resembling', and virescens is Latin for 'greenish'. The green heron is relatively small; adult body length is about 44 cm (17 in). The neck is often pulled in tight against the body. Adults have a glossy, greenish-black cap, a greenish back and wings that are grey-black grading into green or blue, a chestnut neck with a white line down the front, grey underparts and short yellow legs. The bill is dark with a long, sharp point. Female adults tend to be smaller than males, and have duller and lighter plumage, particularly in the breeding season. Juveniles are duller, with the head sides, neck and underparts streaked brown and white, tan-splotched back and wing coverts, and greenish-yellow legs and bill. Hatchlings are covered in down feathers, light grey above, and white on the belly. (Source: Wikipedia.org, CC BY-SA)
Cotinis nitida, commonly known as the green June beetle, June bug or June beetle, is a beetle of the family Scarabaeidae. It is found in the eastern United States and Canada, where it is most abundant in the South. It is sometimes confused with the related southwestern species figeater beetle Cotinis mutabilis, which is less destructive. The green June beetle is active during daylight hours. The adult is usually 15–22 mm (0.6–0.9 in) long with dull, metallic green wings; its sides are gold and the head, legs and underside are very bright shiny green. Their habitat extends from New Brunswick to Georgia, and as far west as California, with possible population crossover in Texas with their western cousin, the figeater beetle.

The green moray (Gymnothorax funebris) is a moray eel of the family Muraenidae, found in the western Atlantic Ocean from New Jersey, Bermuda, and the northern Gulf of Mexico to Brazil, at depths down to 40 metres (130 ft). Its length is up to 2.5 metres (8.2 ft). The common name 'green moray' is also sometimes used to refer to the yellow moray, G. prasinus. (Source: Wikipedia.org, CC BY-SA)
Guineafowl (/ˈɡɪnifaʊl/; sometimes called 'pet speckled hens' or 'original fowl') are birds of the family Numididae in the order Galliformes. They are endemic to Africa and rank among the oldest of the gallinaceous birds. Phylogenetically, they branched off from the core Galliformes after the Cracidae (chachalacas, guans, and curassows) and before the Odontophoridae (New World quail). An Eocene fossil lineage Telecrex has been associated with guineafowl; Telecrex inhabited Mongolia, and may have given rise to the oldest of the true phasianids, such as blood pheasants and eared pheasants, which evolved into high-altitude, montane-adapted species with the rise of the Tibetan Plateau. While modern guineafowl species are endemic to Africa, the helmeted guineafowl has been introduced as a domesticated bird widely elsewhere. The insect- and seed-eating, ground-nesting birds of this family resemble partridges, but with featherless heads, though both members of the genus Guttera have a distinctive black crest, and the vulturine guineafowl has a downy brown patch on the nape. Most species of guineafowl have a dark grey or blackish plumage with dense white spots, but both members of the genus Agelastes lack the spots. While several species are relatively well known, the plumed guineafowl and the two members of the genus Agelastes remain relatively poorly known. These large birds measure 40–71 cm (15+1⁄2–28 in) in length, and weigh 700–1,600 g (1 lb 9 oz – 3 lb 8 oz). Guinea hens weigh more than guinea cocks, possibly because of the larger reproductive organs in the female compared to the male guinea fowl. Also, the presence of relatively larger egg clusters in the dual-purpose guinea hens may be a factor that contributes to the higher body weight of the guinea hens. (Source: Wikipedia.org, CC BY-SA)
The guinea pig or domestic guinea pig (Cavia porcellus), also known as the cavy or domestic cavy (/ˈkeɪvi/), is a species of rodent belonging to the genus Cavia in the family Caviidae. Breeders tend to use the word cavy to describe the animal, while in scientific and laboratory contexts, it is far more commonly referred to by the common name guinea pig. Despite their common name, guinea pigs are not native to Guinea, nor are they closely related biologically to pigs, and the origin of the name is still unclear. They originated in the Andes of South America. Studies based on biochemistry and hybridization suggest they are domesticated animals that do not exist naturally in the wild, descendants of a closely related cavy species such as C. tschudii. They were originally domesticated as livestock for a source of meat, and are still consumed in some parts of the world. In Western society, the guinea pig has enjoyed widespread popularity as a pet since its introduction to Europe and North America by European traders in the 16th century. Their docile nature, friendly responsiveness to handling and feeding, and the relative ease of caring for them have made guinea pigs a continuing popular choice of household pet. Organizations devoted to the competitive breeding of guinea pigs have been formed worldwide. Many specialized breeds, with varying coat colors and textures, are selected by breeders.

The guppy (Poecilia reticulata), also known as millionfish and rainbow fish, is one of the world's most widely distributed tropical fish and one of the most popular freshwater aquarium fish species. It is a member of the family Poeciliidae and, like almost all American members of the family, is live-bearing. Guppies originate from northeast South America, but have been introduced to many environments and are now found all over the world. They are highly adaptable and thrive in many different environmental and ecological conditions. Male guppies, which are smaller than females, have ornamental caudal and dorsal fins. Wild guppies generally feed on a variety of food sources, including benthic algae and aquatic insect larvae. Guppies are used as a model organism in the fields of ecology, evolution, and behavioural studies. Guppies exhibit sexual dimorphism. While wild-type females are grey in body color, males have splashes, spots, or stripes that can be any of a wide variety of colors. The development and exhibiting of color patterns in male guppies is usually due to the amount of thyroid hormone that they contain. The thyroid hormones not only influence color pattern, but control endocrine function in response to their environment. The size of guppies vary, but males are typically 1.5–3.5 cm (0.6–1.4 in) long, while females are 3–6 cm (1.2–2.4 in) long. (Source: Wikipedia.org, CC BY-SA)
Hares and jackrabbits are mammals belonging to the genus Lepus. They are herbivores, and live solitarily or in pairs. They nest in slight depressions called forms, and their young are able to fend for themselves shortly after birth. The genus includes the largest lagomorphs. Most are fast runners with long, powerful hind legs, and large ears to dissipate body heat. Hare species are native to Africa, Eurasia and North America. A hare less than one year old is called a 'leveret'. A group of hares is called a 'husk', a 'down' or a 'drove'. Hares and rabbits are plentiful in many areas, adapt to a wide variety of conditions, and reproduce quickly, so hunting is often less regulated than for other varieties of game. In rural areas of North America and particularly in pioneer times, they were a common source of meat. Because of their extremely low fat content, they are a poor choice as a survival food.

Hawks are birds of prey of the family Accipitridae. They are widely distributed and are found on all continents except Antarctica. Starting in the hawk's early life, it is fed by its parents until it leaves the nest. The young hawk, while still in its fledgling phase, will leave its nest as early as six weeks old. Once the bird is older it begins to hunt. The hawk kills its prey with its talons as opposed to other predator birds, such as the falcon. The falcon uses its talons to catch the prey but kills the small animal with its beak instead of its talons.[citation needed] The hawk's preferred time for hunting is usually just before nightfall when daylight lessens. Although the hawk is known for being a violent predator, some are gentle and quiet.[citation needed] When it flies, the hawk flaps its wings rapidly, and then uses that momentum to glide smoothly and gracefully through the air.

A hedgehog is a spiny mammal of the subfamily Erinaceinae, in the eulipotyphlan family Erinaceidae. There are seventeen species of hedgehog in five genera found throughout parts of Europe, Asia, and Africa, and in New Zealand by introduction. There are no hedgehogs native to Australia and no living species native to the Americas. However, the extinct genus Amphechinus was once present in North America. Hedgehogs are easily recognized by their spines, which are hollow hairs made stiff with keratin. Their spines are not poisonous or barbed and, unlike the quills of a porcupine, do not easily detach from their bodies. However, the immature animal's spines normally fall out as they are replaced with adult spines. This is called 'quilling'. Spines can also shed when the animal is diseased or under extreme stress. Hedgehogs are usually brown, with pale tips to the spines, though blonde hedgehogs are found on the Channel Island of Alderney. (Source: Wikipedia.org, CC BY-SA)
Hermit crabs are anomuran decapod crustaceans of the superfamily Paguroidea that have adapted to occupy empty scavenged mollusc shells to protect their fragile exoskeletons. There are over 800 species of hermit crab, most of which possess an asymmetric abdomen concealed by a snug-fitting shell. Hermit crabs' soft (non-calcified) abdominal exoskeleton means they must occupy shelter produced by other organisms or risk being defenseless. The strong association between hermit crabs and their shelters has significantly influenced their biology. Almost 800 species carry mobile shelters (most often calcified snail shells); this protective mobility contributes to the diversity and multitude of crustaceans found in almost all marine environments. In most species, development involves metamorphosis from symmetric, free-swimming larvae to morphologically asymmetric, benthic-dwelling, shell-seeking crabs. Such physiological and behavioral extremes facilitate a transition to a sheltered lifestyle, revealing the extensive evolutionary lengths that led to their superfamily success. Most species have long, spirally curved abdomens, which are soft, unlike the hard, calcified abdomens seen in related crustaceans. The vulnerable abdomen is protected from predators by a salvaged empty seashell carried by the hermit crab, into which its whole body can retract. Most frequently, hermit crabs use the shells of sea snails (although the shells of bivalves and scaphopods and even hollow pieces of wood and stone are used by some species). The tip of the hermit crab's abdomen is adapted to clasp strongly onto the columella of the snail shell. Most hermit crabs are nocturnal.[citation needed] (Source: Wikipedia.org, CC BY-SA)
The herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera Botaurus and Ixobrychus are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus Zebrilus, form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks. The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, Ardea and Egretta. Similarly, the relationships of the genera in the family are not completely resolved. However, one species formerly considered to constitute a separate monotypic family, the Cochlearidae or the boat-billed heron, is now regarded as a member of the Ardeidae.

The hippopotamus (/ˌhɪpəˈpɒtəməs/ HIP-ə-POT-ə-məs; pl: hippopotamuses or hippopotami; Hippopotamus amphibius), also called the hippo, common hippopotamus, or river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (Choeropsis liberiensis or Hexaprotodon liberiensis). Its name comes from the ancient Greek for 'river horse' (ἱπποπόταμος). Aside from elephants and rhinos, the hippopotamus is the largest land mammal. It is also the largest extant land artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from which they diverged about 55 million years ago. Hippos are recognisable for their barrel-shaped torsos, wide-opening mouths with large canine tusks, nearly hairless bodies, pillar-like legs, and large size: adults average 1,500 kg (3,310 lb) for bulls (males) and 1,300 kg (2,870 lb) for cows (females). Despite its stocky shape and short legs, it is capable of running 30 km/h (19 mph) over short distances. (Source: Wikipedia.org, CC BY-SA)
Hornbills (Bucerotidae) are a family of bird found in tropical and subtropical Africa, Asia and Melanesia. They are characterized by a long, down-curved bill which is frequently brightly coloured and sometimes has a casque on the upper mandible. Both the common English and the scientific name of the family refer to the shape of the bill, 'buceros' being 'cow horn' in Greek. Hornbills have a two-lobed kidney. They are the only birds in which the first and second neck vertebrae (the atlas and axis respectively) are fused together; this probably provides a more stable platform for carrying the bill. The family is omnivorous, feeding on fruit and small animals. They are monogamous breeders nesting in natural cavities in trees and sometimes cliffs. A number of mainly insular species of hornbill with small ranges are threatened with extinction, namely in Southeast Asia. Hornbills show considerable variation in size. The smallest species is the black dwarf hornbill (Tockus hartlaubi), at 99.1 g (3.50 oz) and 32 cm (1 ft 1 in) in length. The largest and most massive species appears to be the southern ground hornbill which has an average weight of 3.77 kg (8.3 lb), and can weigh up to 6.3 kg (14 lb) and span about 180 cm (5 ft 11 in) across the wings. Other species rival the southern ground species in length, at up to about 130 cm (4 ft 3 in), including the Abyssinian ground hornbill (Bucorvus abyssinicus), the great hornbill (Buceros bicornis) and, probably the longest of all (perhaps exceeding 150 cm (4 ft 11 in)) thanks in part to its extended tail feathers, the helmeted hornbill (Rhinoplax vigil). Males are always bigger than the females, though the extent to which this is true varies according to species. The extent of sexual dimorphism also varies with body parts. For example, the difference in body mass between males and females is 1–17%, but the variation is 8–30% for bill length and 1–21% in wing length. (Source: Wikipedia.org, CC BY-SA)
The horse (Equus ferus caballus) is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of Equus ferus. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Eohippus, into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies caballus are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, as this term is used to describe horses that have never been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior. Horses are adapted to run, allowing them to quickly escape predators, and possess an excellent sense of balance and a strong fight-or-flight response. Related to this need to flee from predators in the wild is an unusual trait: horses are able to sleep both standing up and lying down, with younger horses tending to sleep significantly more than adults. Female horses, called mares, carry their young for approximately 11 months and a young horse, called a foal, can stand and run shortly following birth. Most domesticated horses begin training under a saddle or in a harness between the ages of two and four. They reach full adult development by age five, and have an average lifespan of between 25 and 30 years. (Source: Wikipedia.org, CC BY-SA)
Hummingbirds are birds native to the Americas and comprise the biological family Trochilidae. With about 361 species and 113 genera, they occur from Alaska to Tierra del Fuego, but the vast majority of the species are found in the tropics around the equator. They are small birds, with most species measuring 7.5–13 cm (3–5 in) in length. The smallest extant hummingbird species is the 5 cm (2.0 in) bee hummingbird, which weighs less than 2.0 g (0.07 oz). The largest hummingbird species is the 23 cm (9.1 in) giant hummingbird, weighing 18–24 grams (0.63–0.85 oz). They are specialized for feeding on flower nectar, but all species also consume flying insects or spiders. Hummingbirds split from their sister group, the swifts and treeswifts, around 42 million years ago. The common ancestor of extant hummingbirds is estimated to have lived 22 million years ago in South America. They are known as hummingbirds because of the humming sound created by their beating wings, which flap at high frequencies audible to humans. They hover in mid-air at rapid wing-flapping rates, which vary from around 12 beats per second in the largest species to around 80 per second in small hummingbirds. Of those species that have been measured during flying in wind tunnels, their top speeds exceed 15 m/s (54 km/h; 34 mph). During courtship, some male species dive from 30 metres (100 ft) of height above a female at speeds around 23 m/s (83 km/h; 51 mph). (Source: Wikipedia.org, CC BY-SA)
The humpback whale (Megaptera novaeangliae) is a species of baleen whale. It is a rorqual (a member of the family Balaenopteridae) and is the only species in the genus Megaptera. Adults range in length from 14–17 m (46–56 ft) and weigh up to 40 metric tons (44 short tons). The humpback has a distinctive body shape, with long pectoral fins and tubercles on its head. It is known for breaching and other distinctive surface behaviors, making it popular with whale watchers. Males produce a complex song typically lasting 4 to 33 minutes. Found in oceans and seas around the world, humpback whales typically migrate up to 16,000 km (9,900 mi) each year. They feed in polar waters and migrate to tropical or subtropical waters to breed and give birth. Their diet consists mostly of krill and small fish, and they use bubbles to catch prey. They are promiscuous breeders, with both sexes having multiple partners. Orcas are the main natural predators of humpback whales. (Source: Wikipedia.org, CC BY-SA)
Hyenas, or hyaenas (from Ancient Greek ὕαινα, hýaina), are feliform carnivoran mammals of the family Hyaenidae /haɪˈɛnɪdiː/. With only four extant species (each in its own genus), it is the fifth-smallest family in the Carnivora and one of the smallest in the class Mammalia. Despite their low diversity, hyenas are unique and vital components of most African ecosystems. Although phylogenetically closer to felines and viverrids, as part of suborder Feliformia, hyenas are behaviourally and morphologically similar to canids in several elements due to convergent evolution; both hyenas and canines are non-arboreal, cursorial hunters that catch prey with their teeth rather than claws. Both eat food quickly and may store it, and their calloused feet with large, blunt, nonretractable claws are adapted for running and making sharp turns. However, hyenas' grooming, scent marking, defecation habits, mating and parental behavior are consistent with the behavior of other feliforms. (Source: Wikipedia.org, CC BY-SA)
An ibex (plural ibex, ibexes or ibices) is any of several species of wild goat (genus Capra), distinguished by the male's large recurved horns, which are transversely ridged in front. Ibex are found in Eurasia, North Africa and East Africa. The name ibex comes from Latin, borrowed from Iberian or Aquitanian, akin to Old Spanish bezerro 'bull', modern Spanish becerro 'yearling'. Ranging in height from 70 to 110 centimetres (27–43 in) and weighing 90 to 120 kilograms (200–270 lb), ibex can live 20 years. Two closely related varieties of goats found in the wild are not usually called ibex: the markhor and the feral goat. A male ibex is referred to as a buck, a female is a doe, and young juveniles are called kids. An ibex buck is commonly larger and heavier than a doe. The most noticeable difference between the sexes is the larger size of a buck's horns. The doe grows a pair of smaller, thinner horns which develop considerably more slowly than those of a buck. The ibex's horns appear at birth and continue to grow through the rest of its life. (Source: Wikipedia.org, CC BY-SA)
The ibises (/ˈaɪbɪs/) (collective plural ibis; classical plurals ibides and ibes) are a group of long-legged wading birds in the family Threskiornithidae, that inhabit wetlands, forests and plains. 'Ibis' derives from the Latin and Ancient Greek word for this group of birds. It also occurs in the scientific name of the cattle egret (Bubulcus ibis) mistakenly identified in 1757 as being the sacred ibis. Ibises all have long, downcurved bills, and usually feed as a group, probing mud for food items, usually crustaceans. They are monogamous and highly territorial while nesting and feeding. Most nest in trees, often with spoonbills or herons. All extant species are capable of flight, but two extinct genera were flightless, namely the kiwi-like Apteribis in the Hawaiian Islands, and the peculiar Xenicibis in Jamaica. The word ibis comes from Latin ibis from Greek ἶβις ibis from Egyptian hb, hīb. (Source: Wikipedia.org, CC BY-SA)
Iguana (/ɪˈɡwɑːnə/, Spanish: [iˈɣwana]) is a genus of herbivorous lizards that are native to tropical areas of Mexico, Central America, South America, and the Caribbean. The genus was first described in 1768 by Austrian naturalist Josephus Nicolaus Laurenti in his book Specimen Medicum, Exhibens Synopsin Reptilium Emendatam cum Experimentis circa Venena. Two species are placed in the genus, the green iguana, which is widespread throughout its range and a popular pet, and the Lesser Antillean iguana, which is native to the Lesser Antilles. Genetic analysis indicates that the green iguana may comprise a complex of multiple species, some of which have been recently described, but the Reptile Database considers all of these as subspecies of the green iguana. Iguanas can range from 1.5 to 1.8 m (5 to 6 ft) in length, including their tails. These lizards possess a dewlap and a row of elongated scales running from the midline of their necks down to their tails. Iguanas have varying types of scales covering different areas of their body, for example, some large, round tuberculate scales are scattered around the lateral region of the neck among smaller, overlapping scales. The scales on the dorsal trunk of their bodies are also thicker and more tightly packed than those on the ventral sides. These scales may be a variety of colors and are not always visible from close distances. They have a large, round scale on their cheeks known as a subtympanic shield. Iguanas have keen vision and can see shapes, shadows, colors, and movement at long distances. Their visual acuity enables them to navigate through crowded forests and to locate food. They employ visual signals to communicate with other members of the same species. (Source: Wikipedia.org, CC BY-SA)
The impala or rooibok (Aepyceros melampus) is a medium-sized antelope found in eastern and southern Africa. The only extant member of the genus Aepyceros and tribe Aepycerotini, it was first described to European audiences by German zoologist Hinrich Lichtenstein in 1812. Two subspecies are recognised—the common impala, and the larger and darker black-faced impala. The impala reaches 70–92 cm (28–36 in) at the shoulder and weighs 40–76 kg (88–168 lb). It features a glossy, reddish brown coat. The male's slender, lyre-shaped horns are 45–92 cm (18–36 in) long. Active mainly during the day, the impala may be gregarious or territorial depending upon the climate and geography. Three distinct social groups can be observed: the territorial males, bachelor herds and female herds. The impala is known for two characteristic leaps that constitute an anti-predator strategy. Browsers as well as grazers, impala feed on monocots, dicots, forbs, fruits and acacia pods (whenever available). An annual, three-week-long rut takes place toward the end of the wet season, typically in May. Rutting males fight over dominance, and the victorious male courts female in oestrus. Gestation lasts six to seven months, following which a single calf is born and immediately concealed in cover. Calves are suckled for four to six months; young males—forced out of the all-female groups—join bachelor herds, while females may stay back. (Source: Wikipedia.org, CC BY-SA)
Isopoda is an order of crustaceans that includes woodlice and their relatives. Isopods live in the sea, in fresh water, or on land. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration. Females brood their young in a pouch under their thorax. Isopods have various feeding methods: some eat dead or decaying plant and animal matter, others are grazers, or filter feeders, a few are predators, and some are internal or external parasites, mostly of fish. Aquatic species mostly live on the seabed or bottom of freshwater bodies of water, but some taxa can swim for a short distance. Terrestrial forms move around by crawling and tend to be found in cool, moist places. Some species are able to roll themselves into a ball as a defense mechanism or to conserve moisture.

Jackals are medium-sized canids native to Africa and Eurasia. While the word 'jackal' has historically been used for many canines of the subtribe canina, in modern use it most commonly refers to three species: the closely related black-backed jackal (Lupulella mesomelas) and side-striped jackal (Lupulella adusta) of sub-Saharan-Africa, and the golden jackal (Canis aureus) of south-central Europe and Asia. The African golden wolf (Canis lupaster) was also formerly considered as a jackal. While they do not form a monophyletic clade, all jackals are opportunistic omnivores, predators of small to medium-sized animals and proficient scavengers. Their long legs and curved canine teeth are adapted for hunting small mammals, birds, and reptiles, and their large feet and fused leg bones give them a physique well-suited for long-distance running, capable of maintaining speeds of 16 km/h (10 mph) for extended periods of time. Jackals are crepuscular, most active at dawn and dusk. (Source: Wikipedia.org, CC BY-SA)
A jay is a member of a number of species of medium-sized, usually colorful and noisy, passerine birds in the Crow family, Corvidae. The evolutionary relationships between the jays and the magpies are rather complex. For example, the Eurasian magpie seems more closely related to the Eurasian jay than to the East Asian blue and green magpies, whereas the blue jay is not closely related to either. Jays are not a monophyletic group. Anatomical and molecular evidence indicates they can be divided into an American and an Old World lineage (the latter including the ground jays and the piapiac), while the grey jays of the genus Perisoreus form a group of their own. The black magpies, formerly believed to be related to jays, are classified as treepies. (Source: Wikipedia.org, CC BY-SA)
Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are anchored to the seabed by stalks rather than being mobile. The bell can pulsate to provide propulsion for highly efficient locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex life cycle; the medusa is normally the sexual phase, which produces planula larvae that disperse widely and enter a sedentary polyp phase before reaching sexual maturity. Jellyfish are found all over the world, from surface waters to the deep sea. Scyphozoans (the 'true jellyfish') are exclusively marine, but some hydrozoans with a similar appearance live in freshwater. Large, often colorful, jellyfish are common in coastal zones worldwide. The medusae of most species are fast-growing, and mature within a few months then die soon after breeding, but the polyp stage, attached to the seabed, may be much more long-lived. Jellyfish have been in existence for at least 500 million years, and possibly 700 million years or more, making them the oldest multi-organ animal group. Jellyfish are eaten by humans in certain cultures. They are considered a delicacy in some Asian countries, where species in the Rhizostomae order are pressed and salted to remove excess water. Australian researchers have described them as a 'perfect food', sustainable, and protein-rich but relatively low in food energy. (Source: Wikipedia.org, CC BY-SA)
Kangaroos are four marsupials from the family Macropodidae (macropods, meaning 'large foot'). In common use the term is used to describe the largest species from this family, the red kangaroo, as well as the antilopine kangaroo, eastern grey kangaroo, and western grey kangaroo. Kangaroos are indigenous to Australia and New Guinea. The Australian government estimates that 42.8 million kangaroos lived within the commercial harvest areas of Australia in 2019, down from 53.2 million in 2013. As with the terms 'wallaroo' and 'wallaby', 'kangaroo' refers to a paraphyletic grouping of species. All three terms refer to members of the same taxonomic family, Macropodidae, and are distinguished according to size. The largest species in the family are called 'kangaroos' and the smallest are generally called 'wallabies'. The term 'wallaroos' refers to species of an intermediate size. There are also the tree-kangaroos, another type of macropod, which inhabit the tropical rainforests of New Guinea, far northeastern Queensland and some of the islands in the region. This kind of kangaroo lives in the upper branches of trees. (Source: Wikipedia.org, CC BY-SA)
Kingfishers are a family, the Alcedinidae, of small to medium-sized, brightly colored birds in the order Coraciiformes. They have a cosmopolitan distribution, with most species found in the tropical regions of Africa, Asia, and Oceania, but also can be seen in Europe. They can be found in deep forests near calm ponds and small rivers. The family contains 114 species and is divided into three subfamilies and 19 genera. All kingfishers have large heads, long, sharp, pointed bills, short legs, and stubby tails. Most species have bright plumage with only small differences between the sexes. Most species are tropical in distribution, and a slight majority are found only in forests. They consume a wide range of prey usually caught by swooping down from a perch. While kingfishers are usually thought to live near rivers and eat fish, many species live away from water and eat small invertebrates. Like other members of their order, they nest in cavities, usually tunnels dug into the natural or artificial banks in the ground. Some kingfishers nest in arboreal termite nests. A few species, principally insular forms, are threatened with extinction. In Britain, the word 'kingfisher' normally refers to the common kingfisher. (Source: Wikipedia.org, CC BY-SA)
Kite (/ˈkaɪt/) is the common name for certain birds of prey in the family Accipitridae, particularly in subfamilies Milvinae, Elaninae, and Perninae. The term is derived from Old English cȳta (“kite; bittern”), from the Proto-Indo-European root *gū- , 'screech.' Some authors use the terms 'hovering kite' and 'soaring kite' to distinguish between Elanus and the milvine kites, respectively.[according to whom?] The group may also be differentiated by size, referring to milvine kites as 'large kites', and elanine kites as 'small kites'.

The koala or, inaccurately, koala bear (Phascolarctos cinereus), is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae and its closest living relatives are the wombats. The koala is found in coastal areas of the mainland's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, spoon-shaped nose. The koala has a body length of 60–85 cm (24–33 in) and weighs 4–15 kg (9–33 lb). Fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations possibly are separate subspecies, but this is disputed. Koalas typically inhabit open Eucalyptus woodland, as the leaves of these trees make up most of their diet. Because this eucalypt diet has limited nutritional and caloric content, koalas are largely sedentary and sleep up to twenty hours a day. They are asocial animals, and bonding exists only between mothers and dependent offspring. Adult males communicate with loud bellows that intimidate rivals and attract mates. Males mark their presence with secretions from scent glands located on their chests. Being marsupials, koalas give birth to underdeveloped young that crawl into their mothers' pouches, where they stay for the first six to seven months of their lives. These young koalas, known as joeys, are fully weaned around a year old. Koalas have few natural predators and parasites, but are threatened by various pathogens, such as Chlamydiaceae bacteria and the koala retrovirus. (Source: Wikipedia.org, CC BY-SA)
Koi (鯉, English: /ˈkɔɪ/, Japanese: [koꜜi]) or more specifically nishikigoi (錦鯉, Japanese: [ɲiɕi̥kiꜜɡoi], literally 'brocaded carp'), are colored varieties of the Amur carp (Cyprinus rubrofuscus) that are kept for decorative purposes in outdoor koi ponds or water gardens. Koi are an omnivorous fish. They eat a wide variety of foods, including peas, lettuce, and watermelon. Koi food is designed not only to be nutritionally balanced, but also to float so as to encourage them to come to the surface. When they are eating, koi can be checked for parasites and ulcers. Naturally, koi are bottom feeders with a mouth configuration adapted for that. Some koi have a tendency to eat mostly from the bottom, so food producers create a mixed sinking and floating combination food. Koi recognize the persons feeding them and gather around them at feeding times. They can be trained to take food from one's hand. In the winter, their digestive systems slow nearly to a halt, and they eat very little, perhaps no more than nibbles of algae from the bottom. Feeding is not recommended when the water temperature drops below 10 °C (50 °F). Care should be taken by hobbyists that proper oxygenation, pH stabilization, and off-gassing occur over the winter in small ponds, so they do not perish. Their appetites do not come back until the water becomes warm in the spring. (Source: Wikipedia.org, CC BY-SA)
The Komodo dragon (Varanus komodoensis), also known as the Komodo monitor, is a member of the monitor lizard family Varanidae that is endemic to the Indonesian islands of Komodo, Rinca, Flores, and Gili Motang. It is the largest extant species of lizard, growing to a maximum length of 3 metres (10 ft), and weighing up to 70 kilograms (150 lb). As a result of their size, Komodo dragons are apex predators, and dominate the ecosystems in which they live. Komodo dragons hunt and ambush prey including invertebrates, birds, and mammals. It has been claimed that they have a venomous bite; there are two glands in the lower jaw that secrete several toxic proteins. The biological significance of these proteins is disputed, but the glands have been shown to secrete an anticoagulant. Komodo dragons' group behavior in hunting is exceptional in the reptile world. The diet of Komodo dragons mainly consists of Javan rusa (Rusa timorensis), though they also eat considerable amounts of carrion. Komodo dragons also occasionally attack humans.

Kookaburras are terrestrial tree kingfishers of the genus Dacelo native to Australia and New Guinea, which grow to between 28 and 47 cm (11 and 19 in) in length and weigh around 300 g (11 oz). The name is a loanword from Wiradjuri guuguubarra, onomatopoeic of its call. The loud, distinctive call of the laughing kookaburra is widely used as a stock sound effect in situations that involve an Australian bush setting or tropical jungle, especially in older movies. They are found in habitats ranging from humid forest to arid savannah, as well as in suburban areas with tall trees or near running water. Though they belong to the larger group known as 'kingfishers', kookaburras are not closely associated with water. Kookaburras are almost exclusively carnivorous, eating mice, snakes, insects, small reptiles, and the young of other birds; unlike many other kingfishers, they rarely eat fish, although they have been known to take goldfish from garden ponds. In zoos, they are usually fed food for birds of prey. (Source: Wikipedia.org, CC BY-SA)

Que je clique n'importe ou, j'ai des textes en flamand du genre "De door u aangevraagde pagina kon niet geladen worden Indien u deze url zelf ingetypt heeft, check of deze correct is Klik hier om naar de homepagina te gaan." Il n'y a pas moyen de le mettre en Francais, c'est de la discrimination !
La question sur la pente est pas claire, la pente est la descente tandis que pour une montée c'est une côte.

Pas de vitesse minimale sur l'autoroute? Je suis étonné. Je pensais qu'il s'agissait de 70 km/hr.
C'est un peu dificir d'etudies de règles de lå circulation sur internet, ici en Sweden pas de livres en france alors comment nous devon faire?

j'ai eu 1/ fin de l'autoroute 2/ fin de l'autoroute 3/ x 4/ y je prends la réponse 1, on me dit que j'ai faux et que j'aurais dû choisir 2... "lumière tamisée" pour feux de croisement, traduction vraiment approximative... Bon en gros c'est juste un quizz panneaux, ça me permet de découvrir un peu, mais je reste sceptique sur la qualité du tout. Je remercie l'effort.

Hello, J'ai repassé le test après des années pour me tester, mais... 1) Les questions ne sont pas précises. 2) Certaines fautes sont à déplorer (p.ex "Vitesse minimale sur une autoroute => 70km/h. Réponse du site : "Aucune limitation minimale")

47/50 Bon site mais certain terme dans l'examen sont pas precis/ pas les meme que dans le vrai examen

Site attractif dans sa conception; cependant nécessite plus de sérieux et d'actualisation sur les questionnaires. Des formulations pas du tout correctes( dû certainement à une maivaise traduction en français. ce qui enduit en erreur l'apprenant qui est pourtant là pour plus de clarté et de précisions). Des réponses à des questions qui se contredise: exemple; la question sur quand on consomme plus de carburant, quelque part on te dit à basse vitesse, ailleurs à haute vitesse..on se fie à quoi dans ce cas? La liste étant exhautive.. Merci de reviser cette plateforme et y apporter les ajustements nécessaires car les gens payent pour apprendre sérieusement et non pas pour être plus embrouillés. Positivement!

46/50 super bon exercice et bon site Faut à la question: que indique ce panneau (autoroute) 2x la même réponse donc eu faut car j'ai selectionnée une des deux et pas la bonne et sur l'autoroute j'ai été vérifier, il est bien marquer 80km/h Mais sinon super bon site un grand merci ;-))

pour moi qui doit passer mon permis de conduire j'ai fais un 46 sur 50 et des bonnes questions
Bonjour, il y a un jour ou deux j'ai croisé la route de chasseurs qui faisaient une battue... ils avaient mis des panneaux au bord de la route (style " battue en cours") Est ce que la vitesse autorisée entre ces panneaux est la vitesse "normale" de circulation ou est ce qu'il y a une vitesse d' "exception"..? ( j'étais a 70 Km/h sur une route a 90 Km/h et les chasseurs me faisaient des signes "genre je roulais trop vite"...) Merci de votre réponse. BAV.

nouveaux nom pour les feux : apres verification a vias connait pas saillants ou tamisé( nouvelle invention ou traduction erronée
0
question des feux tamisé ou saillant n existe pas: feux de croisements ou de route
beaucoup d'erreurs de traduction. question ne correspondent pas aux panneaux, autoroutes/routes ordinaire.
La question sur la vitesse minimal sur l'autoroute est fausse. Il indique la correct étant comme "Il n'y a pas vitesse minimal", alors que de savoir, et après vérificaiton, elle est en faite à 80KM/H
la question 33 que de ce questionnaire était fausse pour ma part : elle déclare que le panneau C25 (selon le Feu Vert, 14 ème édition, 2019) est un panneau réglementant le stationnement, alors que selon l'ouvrage précité, il place une interdiction de passage pour les véhicules ou train de véhicules ayant une longueur supérieure à celle indiquée sur le panneau.
