The gharial (Gavialis gangeticus), also known as gavial or fish-eating crocodile, is a crocodilian in the family Gavialidae and among the longest of all living crocodilians. Mature females are 2.6–4.5 m (8 ft 6 in – 14 ft 9 in) long, and males 3–6 m (9 ft 10 in – 19 ft 8 in). Adult males have a distinct boss at the end of the snout, which resembles an earthenware pot known as a ghara, hence the name 'gharial'. The gharial is well adapted to catching fish because of its long, narrow snout and 110 sharp, interlocking teeth. The gharial probably evolved in the northern Indian subcontinent. Fossil gharial remains were excavated in Pliocene deposits in the Sivalik Hills and the Narmada River valley. It currently inhabits rivers in the plains of the northern part of the Indian subcontinent. It is the most thoroughly aquatic crocodilian, and leaves the water only for basking and building nests on moist sandbanks. Adults mate at the end of the cold season. Females congregate in spring to dig nests, in which they lay 20–95 eggs. They guard the nests and the young, which hatch before the onset of the monsoon. The hatchlings stay and forage in shallow water during their first year, but move to sites with deeper water as they grow. (Source: Wikipedia.org, CC BY-SA)
The Gila monster (Heloderma suspectum, /ˈhiːlə/ HEE-lə) is a species of venomous lizard native to the Southwestern United States and the northwestern Mexican state of Sonora. It is a heavy, typically slow-moving reptile, up to 56 centimetres (22 in) long, and it is the only venomous lizard native to the United States. Its venomous close relatives, the four beaded lizards (all former subspecies of Heloderma horridum) inhabit Mexico and Guatemala. The Gila monster is sluggish in nature, so it is not generally dangerous and very rarely poses a real threat to humans. However, it has a fearsome reputation and is sometimes killed in spite of the species being protected by state law in Arizona. The Gila monster is the largest extant lizard species native to North America north of the Mexican border. Its snout-to-vent length ranges from 26 to 36 cm (10 to 14 in). The tail is about 20% of the body size, and the largest specimens may reach 51 to 56 cm (20 to 22 in) in total length. Body mass is typically in the range of 550 to 800 g (1.21 to 1.76 lb). They appear strong in their body structure with a stout snout, massive head, and 'little'-appearing eyes, which can be protected by a nictitating membrane. (Source: Wikipedia.org, CC BY-SA)

A glass lizard, or glass snake, is one of several lizard species belonging to the family Anguidae, so called because their tail easily breaks or snaps off. They are native to North America, Europe, Asia, and North Africa. Their origins started in Europe and spread towards Asia after the drying of the Turgai Sea and then across Beringia to the North America region. (Source: Wikipedia.org, CC BY-SA)
Bothrops insularis, commonly known as the golden lancehead, is a highly venomous pit viper species endemic to Ilha da Queimada Grande, off the coast of São Paulo state, in Brazil. The species is named for the light yellowish-brown color of its underside and for its head shape that is characteristic of the genus Bothrops. No subspecies of Bothrops insularis are currently recognized. It is one of the most venomous snakes in Latin America. On average, B. insularis grows to a length of 70 cm (28 in) and 90 cm (35 in), and it is known to reach 118 cm (46 in). The color pattern consists of a pale yellowish-brown ground color, overlaid with a series of dorsal blotches that may be triangular or quadrangular, broad or narrow, and alternating or opposite along the dorsal median. In captivity, this yellowish color often becomes darker, which may be the result of poor circulation caused by ineffective thermoregulation. A banded pattern results when the pattern is opposite. The head lacks a well-defined post-orbital stripe. The belly is a uniform pale yellow or cream. The name 'lancehead' refers to the distinctive head shape of all snakes in the genus Bothrops, which is somewhat elongated and comes to a point at the nose. B. insularis also has a longer tail than its closest relative, B. jararaca, which is most likely an adaptation to help the snake maneuver through the trees, and to eat larger prey like birds from a younger age.

The gopher snake has a unique defensive mechanism, in which it puffs up its body and curls itself into the classic strike pose of a rattlesnake. However, rather than delivering an open-mouthed strike, the gopher snake often strikes with a closed mouth, using its blunt nose to 'warn off' possible predators. Additionally, gopher snakes vibrate their tails in a manner similar to rattlesnakes. One paper found that gopher snakes on islands lacking rattlesnakes vibrate their tails for shorter amounts of time than gopher snakes in mainland California, which is home to numerous rattlesnake species. This suggests that gopher snake tail vibration may in fact be rattlesnake mimicry since the behavior appears to be breaking down in areas without rattlesnakes, perhaps because predators on these islands have no reason to evolve to avoid tail-vibrating snakes (rattlesnakes are venomous, gopher snakes are not). Adults are 36-84 in (91–213 cm) in length. Dorsally, they are yellowish or pale brown, with a series of large, dark brown or black blotches, and smaller, dark spots on the sides. Ventrally, they are yellowish, either uniform or with brown markings. (Source: Wikipedia.org, CC BY-SA)
The gopher tortoise (Gopherus polyphemus) is a species of tortoise in the family Testudinidae. The species is native to the southeastern United States. The gopher tortoise is seen as a keystone species because it digs burrows that provide shelter for at least 360 other animal species. G. polyphemus is threatened by predation and habitat destruction. The gopher tortoise is a fairly large terrestrial reptile which possesses forefeet well adapted for burrowing, and elephantine hind feet. These features are common to most tortoises. The front legs have scales to protect the tortoise while burrowing. G. polyphemus is dark brown to gray-black in overall color, with a yellow plastron (bottom shell). A gular projection is evident on the anterior plastron where the head projects from the shell. Sexual dimorphism is evident, with the male gopher tortoise having a concave plastron, while that of the female is flat. In addition, the gular projection of a male plastron is generally longer than that of a female. Straight carapace length of adults usually ranges from 6 to 9.5 in (15 to 24 cm), with a maximum of 16 in (41 cm). The carapace is at least twice as long as it is high. Body mass averages 4 kg (8.8 lb), with a range of 2–6 kg (4.4–13.2 lb). (Source: Wikipedia.org, CC BY-SA)
The grass snake (Natrix natrix), sometimes called the ringed snake or water snake, is a Eurasian non-venomous colubrid snake. It is often found near water and feeds almost exclusively on amphibians. The grass snake is typically dark green or brown in colour with a characteristic yellow or whitish collar behind the head, which explains the alternative name ringed snake. The colour may also range from grey to black, with darker colours being more prevalent in colder regions, presumably owing to the thermal benefits of being dark in colour. The underside is whitish with irregular blocks of black, which are useful in recognizing individuals. It can grow to 1 m (3 ft 3 in) or more in length. Grass snakes are strong swimmers and may be found close to freshwater, although there is evidence individual snakes often do not need bodies of water throughout the entire season. The preferred habitat appears to be open woodland and 'edge' habitat, such as field margins and woodland borders, as these may offer adequate refuge while still affording ample opportunity for thermoregulation through basking. Pond edges are also favoured and the relatively high chance of observing this secretive species in such areas may account for their perceived association with ponds and water. Grass snakes, like most reptiles, are at the mercy of the thermal environment and need to overwinter in areas which are not subject to freezing. Thus, they typically spend the winter underground where the temperature is relatively stable. (Source: Wikipedia.org, CC BY-SA)
Pantherophis emoryi, commonly known as the Great Plains rat snake, is a species of nonvenomous rat snake in the family Colubridae. The species is native to the central part of the United States, from Missouri to Nebraska, to Colorado, south to Texas, and into northern Mexico. The Great Plains rat snake is typically light gray or tan in color, with dark gray, brown, or green-gray blotching down its back, and stripes on either side of the head which meet to form a point between the eyes. It is capable of growing to 3–5 feet (0.91–1.52 m) in total length (including tail). The Great Plains rat snake prefers open grassland or lightly forested habitats, but is also found on coastal plains, semi-arid regions, as well as rocky, moderately mountainous regions. It can often be found on farmland, which often leads to its being erroneously called a chicken snake, and other areas with a relatively high rodent population, which is its primary diet. It will also eat birds, and occasionally snakes, lizards and frogs, all of which it subdues by constriction. It is primarily nocturnal, and oviparous, laying clutches of as many as 25 eggs in the late spring. Like most rat snakes, when agitated, the Great Plains rat snake will shake its tail vigorously, which by itself makes no noise, but when it shakes among dry leaf litter, it can sound remarkably like a rattlesnake, and often leads to misidentification. The Great Plains rat snake tends to remain still for a majority of its time awake, which is odd for a nocturnal being. On average, the Great Plains rat snake only moves 188 m (617 ft) per day. The yellow-bellied racer (Coluber constrictor flaviventris), a snake that often lives in the same habitat, moves more often than the Great Plains rat snake, which could lead to a decline in the Great Plains rat snake's population as it is not as mobile.

The green anaconda (Eunectes murinus), also known as the giant Emerald anaconda, common anaconda, common water boa or sucuri, is a boa species found in South America. It is the heaviest and one of the longest known extant snake species. Like all boas, it is a non-venomous constrictor. The green anaconda is the world's heaviest and one of the world's longest snakes, reaching a length of up to 9.3 m (30 ft 6 in) long. More typical mature specimens reportedly can range up to 5 m (16 ft 5 in), with adult females, with a mean length of about 4.6 m (15 ft 1 in), being generally much larger than the males, which average around 3 m (9 ft 10 in). Weights are less well studied, though reportedly range from 30 to 70 kg (66 to 154 lb) in a typical adult. It is the largest snake native to the Americas. Although it is slightly shorter than the reticulated python, it is far bulkier; the bulk of a 4.5-metre (14 ft 9 in) green anaconda is comparable to that of a 7.4-metre (24 ft 3 in) reticulated python. Reports of anacondas 11–12 m (35–40 ft) or even longer also exist, but such claims must be regarded with caution, as no specimens of such lengths have ever been deposited in a museum and hard evidence is lacking. A US$50,000 cash reward is on offer for anyone who can catch an anaconda 30 ft (9.14 m) or longer. The longest and heaviest verified specimen encountered by Dr. Jesús Antonio Rivas, who had examined more than a thousand anacondas, was a female 9.3 m (30 ft 6 in) long and weighing 250 kg (551 lb 2 oz).

Anolis carolinensis or green anole (US: /əˈnoʊ.li/ ) (among other names below) is a tree-dwelling species of anole lizard native to the southeastern United States and introduced to islands in the Pacific and Caribbean. A small to medium-sized lizard, the green anole is a trunk-crown ecomorph and can change its color to several shades from brown to green. Other common names include the Carolina anole, Carolina green anole, American anole, American green anole, North American green anole and red-throated anole. It is sometimes referred to as the American chameleon (typically in the pet trade) due to its color-changing ability; however, it is not a true chameleon. The green anole is a small to medium-sized lizard, with a slender body. The head is long and pointed with ridges between the eyes and nostrils, and smaller ones on the top of the head. The toes have adhesive pads to facilitate climbing. They exhibit sexual dimorphism, the males being fifteen percent larger. Adult males within a population can be classified within a heavyweight and a lightweight morph. The male dewlap (throat fan) is three times the size of the female's and bright orange to pink, whereas that of the female is lighter in color. The dewlap is usually pink for Anolis carolinensis (more orange-red in A. sagrei) and is very rarely present in females. The color of the dewlap is variable and different from the lizard eye to the human eye. (Source: Wikipedia.org, CC BY-SA)

The eastern green mamba (Dendroaspis angusticeps) is a highly venomous snake species of the mamba genus Dendroaspis native to the coastal regions of southern East Africa. Described by Scottish surgeon and zoologist Andrew Smith in 1849, it has a slender build with a bright green back and green-yellow ventral scales. Adult females average around 2 metres (6 ft 7 in) in length, and males are slightly smaller. A shy and elusive species, the eastern green mamba is rarely seen. This elusiveness is usually attributed to its arboreal habitat and green colouration, which acts as camouflage in its natural environment. It has also been observed to use ambush predation, like many vipers, contrary to the active foraging style typical of other elapid snakes. It preys on birds, eggs, bats, and rodents such as mice, rats, and gerbils. Its venom consists of both neurotoxins and cardiotoxins. Symptoms of envenomation include swelling of the injection site, dizziness, and nausea, accompanied by difficulty breathing and swallowing, irregular heartbeat, and convulsions progressing to respiratory paralysis. Bites that result in severe envenomation can quickly be fatal. (Source: Wikipedia.org, CC BY-SA)
Gonyosoma prasinum (green trinket snake, green bush rat snake or green ratsnake) is a species of colubrid snake found in Asia. Rostral a little broader than deep, just visible from above; suture between the internasals a little shorter than that between the prefrontals; frontal as long as its distance from the end of the snout, shorter than the parietals; loreal square or longer than deep; one or two preoculars; temporals 1+2 or 2+2; upper labials 9, fourth, fifth, and sixth entering the eye; 5 lower labials in contact with the anterior chin-shields, which are as long as the posterior or a little longer. Scales in 19 rows, the 9 to 11 middle rows feebly keeled m the adult, smooth in the young. Ventrals with a lateral keel, 198 to 206; anal entire or divided; subcaudals 100–107. Uniform bright green above; upper lip and lower surface yellowish or greenish white. Total length 3 feet: tail 9 inches. (Source: Wikipedia.org, CC BY-SA)
The green tree python (Morelia viridis) is a species of snake in the family Pythonidae. The species is native to New Guinea, some islands in Indonesia, and the Cape York Peninsula in Australia. First described by Hermann Schlegel in 1872, it was known for many years as Chondropython viridis. As its common name suggests, it is a bright green snake that can reach a total length (including tail) of 2 m (6.6 ft) and a weight of 1.6 kg (3.5 lb), with females slightly larger and heavier than males. Living generally in trees, the green tree python mainly hunts and eats small reptiles and mammals. It is a popular pet, and numbers in the wild have suffered with large-scale smuggling of wild-caught green tree pythons in Indonesia. Despite this, the green tree python is rated as least concern on the IUCN Red List of endangered species. The green tree python is characterized by a relatively slim body. The relatively long tail accounts for about 14% of the total length. The head is large and clearly defined from the neck. The snout is large and angular. The body is triangular in cross section with a visible spine. The species usually reaches a total length (including tail) of 150–180 cm (4.9–5.9 ft), but large females may reach 200 cm (6.6 ft). The size also varies depending on the region of origin. The weight is highly dependent upon the nutritional status of the animal. Males can weigh about 1,100–1,400 g (2.4–3.1 lb), females up to 1,600 g (3.5 lb), although wild specimens are typically much lighter than this. Especially large specimens that can weigh up to 2,200 g (4.9 lb) are invariably females, which, like most snakes, are slightly larger and heavier than males. (Source: Wikipedia.org, CC BY-SA)
The western ground snake (Sonora semiannulata) is a species of small, harmless colubrid snake. The species is endemic to North America. It is sometimes referred to as the common ground snake or variable ground snake, as its patterning and coloration can vary widely, even within the same geographic region. Another common name is miter snake referring to the head marking which suggests a bishop's miter; the synonym 'episcopus' (Latin for 'bishop') is a similar allusion. The western ground snake can grow to a total length (including tail) of 8 to 19 inches (20.3 to 48.3 cm). The color and pattern can vary widely. Individuals can be brown, red, or orange, with black banding, orange or brown striping, or be solid-colored. The underside is typically white or gray. It has smooth dorsal scales, a small head, and the pupil of the eye is round. The western ground snake is typically nocturnal and secretive, but it is common throughout its range. It is often found on roadsides, or in dry drainage ditches at night, foraging for food. (Source: Wikipedia.org, CC BY-SA)
The hellbender (Cryptobranchus alleganiensis), also known as the hellbender salamander, is a species of aquatic giant salamander endemic to the eastern and central United States. It is the largest salamander in North America. A member of the family Cryptobranchidae, the hellbender is the only extant member of the genus Cryptobranchus. Other closely related salamanders in the same family are in the genus Andrias, which contains the Japanese and Chinese giant salamanders. The hellbender, which is much larger than all other salamanders in its geographic range, employs an unusual means of respiration (which involves cutaneous gas exchange through capillaries found in its dorsoventral skin folds), and fills a particular niche—both as a predator and prey—in its ecosystem, which either it or its ancestors have occupied for around 65 million years. The species is listed as Near Threatened on the IUCN Red List of Threatened Species. C. alleganiensis has a flat body and head, with beady dorsal eyes and slimy skin. Like most salamanders, it has short legs with four toes on the front legs and five on its back limbs, and its tail is keeled for propulsion. Their tail is shaped like a rudder, but it is rarely used for swimming; these salamanders use pads on their toes instead to grip rocks and walk up and down streams instead of swimming. The hellbender has working lungs, but gill slits are often retained, although only immature specimens have true gills; the hellbender absorbs oxygen from the water through capillaries of its side frills. Only occasionally leaving the water, the hellbender makes little use of these lungs and the juveniles lose their external lungs after around 18 months Hellbenders use their lungs for buoyancy more than breathing. It is blotchy brown or red-brown in color, with a paler underbelly. (Source: Wikipedia.org, CC BY-SA)
Heterodon is a genus of harmless colubrid snakes endemic to North America. They are stout with upturned snouts and are perhaps best known for their characteristic threat displays. Three species are currently recognized. Members of the genus are commonly known as hognose snakes, hog-nosed snakes, North American hog-nosed snakes, and colloquially as puff adders (though they should not be confused with the venomous African vipers of the genus Bitis). Adults grow to 30–120 cm (12–47 in) in total length. The body is stout and the head is slightly distinct from the neck. The latter is expandable, the anterior ribs being capable of spreading to flatten that portion of the body, similar to a cobra. The tail is short and the anal scale divided. The dorsal scales are keeled with apical pits in 23-25 rows. The rostral scale is projecting, upturned, recurved and keeled dorsally. There are usually 1-20 accessory scales (azygous) that separate the internasals and the prefrontals. A subocular ring is present with 8-12 ocular scales. There are 7-8 upper labials and 9-13 lower labials. The ventrals number 114-152 and the subcaudals 27-60. The color pattern is extremely variable. H. nasicus tends to be sandy-colored with black and white markings, while H. platirhinos varies from reds, greens, oranges, browns, to black depending on locality. They are sometimes blotched and sometimes solid-colored. (Source: Wikipedia.org, CC BY-SA)
The horned adder (Bitis caudalis) is a viper species. It is found in the arid region of southwest Africa, in Angola, Botswana, Namibia; South Africa, and Zimbabwe. It is easily distinguished by the presence of a single, large horn-like scale over each eye.[citation needed] No subspecies are currently recognized. Like all other vipers, it is venomous. A short, stout little viper, it usually averages 30–40 cm (12–15.5 in) in total length (body + tail). The largest specimen reported being seen is a female from southern Botswana measuring 51.5 cm (20.3 in) total length. (Source: Wikipedia.org, CC BY-SA)
Horned lizards (Phrynosoma), also known as horny toads or horntoads, are a genus of North American lizards and the type genus of the family Phrynosomatidae. The common names refer directly to their horns or to their flattened, rounded bodies, and blunt snouts. Horned lizards use a variety of means to avoid predation. Their coloration generally serves as camouflage. When threatened, their first defense is to remain still to avoid detection. If approached too closely, they generally run in short bursts and stop abruptly to confuse the predator's visual acuity. If this fails, they puff up their bodies to cause them to appear more horned and larger, so that they are more difficult to swallow. At least eight species (P. asio, P. cornutum, P. coronatum, P. ditmarsi, P. hernandesi, P. orbiculare, P. solare, and P. taurus) are also able to squirt an aimed stream of blood from the corners of the eyes for a distance up to 5 ft (1.5 m). They do this by restricting the blood flow leaving the head, thereby increasing blood pressure and rupturing tiny vessels around the eyelids. The blood not only confuses predators, but also tastes foul to canine and feline predators. It appears to have no effect against predatory birds. Only three closely related species (P. mcallii, P. modestum, and P. platyrhinos) are certainly known to be unable to squirt blood. (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.

The Indian cobra (Naja naja), also known as the spectacled cobra, Asian cobra, or binocellate cobra, is a species of cobra found in India, Pakistan, Bangladesh, Sri Lanka, Nepal, and Bhutan, and a member of the 'big four' species that are responsible for the most snakebite cases in India. The Indian cobra is a moderately sized, heavy bodied species. This cobra species can easily be identified by its relatively large and quite impressive hood, which it expands when threatened. Many specimens exhibit a hood mark. This hood mark is located at the rear of the Indian cobra's hood. When the hood mark is present, are two circular ocelli patterns connected by a curved line, evoking the image of spectacles. This species has a head which is elliptical, depressed, and very slightly distinct from the neck. The snout is short and rounded with large nostrils. The eyes are medium in size and the pupils are round. The majority of adult specimens range from 1 to 1.5 metres (3.3 to 4.9 ft) in length. Some specimens, particularly those from Sri Lanka, may grow to lengths of 2.1 to 2.2 metres (6.9 to 7.2 ft), but this is relatively uncommon. (Source: Wikipedia.org, CC BY-SA)
The Indian star tortoise (Geochelone elegans) is a threatened tortoise species native to India, Pakistan and Sri Lanka where it inhabits dry areas and scrub forest. It has been listed as Vulnerable on the IUCN Red List since 2016, as the population is thought to comprise more than 10,000 individuals, but with a declining trend. It is threatened by habitat loss and poaching for the illegal wildlife trade. The carapace of G. elegans is very convex, with dorsal shields often forming humps; the lateral margins are nearly vertical; the posterior margin is somewhat expanded and strongly serrated. It has no nuchal scute, and the supracaudal is undivided, and curved inward in the male; the shields are strongly striated concentrically. The first vertebral scute is longer than broad, and the others are broader than long, with the third at least as broad as the corresponding costal. The plastron is large, truncated or openly notched in front, and deeply notched and bifid behind; the suture between the humerals is much longer than that between the femorals; the suture between the pectorals is very short; the axillary and inguinal sutures are rather small. The head is moderate in size, with the forehead swollen, convex, and covered with rather small and irregular shields; the beak is feebly hooked, bi- or tricuspid; the edges of the jaws are denticulated; the alveolar ridge of the upper jaw is strong. The outer-anterior face of the fore limbs have numerous unequal-sized, large, imbricate, bony, pointed tubercles; the heel has large, more or less spur-like tubercles; a group of large conical or subconical tubercles is found on the hinder side of the thigh. The carapace is black, with yellow areolae from which yellow streaks radiate; these streaks are usually narrow and very numerous. The plastron likewise has black and yellow, radiating streaks. The Indian star tortoise can grow to 10 inches long. (Source: Wikipedia.org, CC BY-SA)
Drymarchon is a genus of large nonvenomous colubrid snakes, commonly known as indigo snakes or cribos, found in the Southeastern United States, Central America, and South America. Reaching 3 m (9.8 ft) or more in length, they are among the world's largest colubrid snakes. Indigo snakes are large, robust snakes which can reach a total length (including tail) of over 3 m (9.8 ft). They have smooth dorsal scales, and several color variations, including a glossy blue-black color. This snake genus, Drymarchon, means 'Lord of The Forest'. This is a sexually dimorphic species so the males are larger than the females. This is thought to be due to intraspecies competition from the males. Indigo snakes are diurnal and actively forage for prey. They feed on a broad variety of small animals such as rodents, birds, lizards, frogs, toads, and other snakes, including rattlesnakes. They are not aggressive snakes and will bite only when threatened. Typical threat display includes hissing and shaking of its tail as a warning. (Source: Wikipedia.org, CC BY-SA)

Jackson's chameleon, Jackson's horned chameleon, three-horned chameleon, or Kikuyu three-horned chameleon (Trioceros jacksonii) is a species of chameleon (family Chamaeleonidae) native to East Africa, but also introduced to Hawaii, Florida, and California. Jackson's chameleons are sometimes called three-horned chameleons because males possess three brown horns: one on the nose (the rostral horn) and one above each superior orbital ridge above the eyes (preocular horns), somewhat reminiscent of the ceratopsid dinosaur genus Triceratops. The females generally have no horns, or instead have traces of the rostral horn (in the subspecies T. j. jacksonii and T. j. merumontanus). The coloring is usually bright green, with some individual animals having traces of blue and yellow, but like all chameleons, they change color quickly depending on mood, health, and temperature. Adult males reach a total length (including tail) of up to 38 cm (15 in) and females up to 25 cm (10 in), but more typical lengths are 15 to 25 cm (6 to 10 in). It has a saw-tooth shaped dorsal ridge and no gular crest. It attains sexual maturity after five months. The lifespan is variable, with males generally living longer than females.

The Jamaican boa or yellow snake (Chilabothrus subflavus; Jamaican Patois: nanka) is a boa species endemic to Jamaica. No subspecies are currently recognized. Like all other boas, it is not venomous. The Jamaican boa is golden-green around the head and along the anterior section of the body, with black zigzag crossbars, becoming black toward the posterior end of its body. The snake's body is quite long, up to 2 metres (6 feet 7 inches) in total length. (Source: Wikipedia.org, CC BY-SA)
The Japanese rat snake (Elaphe climacophora) is a medium-sized colubrid snake found throughout the Japanese archipelago (except the far South West) as well as on the Russian-administered Kunashir Island. In Japanese it is known as the aodaishō or 'blue general'. It is non-venomous. It is hunted by eagles and tanukis. The snakes hibernate for three to four months, mate in spring and lay 7–20 eggs in early summer. Adults reach one to two meters in length and about five centimeters in girth. E. climacophora is the largest Japanese snake outside Okinawa. They are variable in color, ranging from pale yellow-green to dark blue-green. Juveniles have brown-stripe pattern that may be mimesis of the venomous mamushi. An albino form is known, with specimens especially numerous near Iwakuni, where they are called 'Iwakuni white snakes' and revered as messengers of deities and deity-guardians of mountains and rivers. The albino population was protected in 1924 as a 'national monument.' (Source: Wikipedia.org, CC BY-SA)
Rhabdophis is a genus of snakes in the subfamily Natricinae of the family Colubridae. Species in the genus Rhabdophis are generally called keelback snakes, and are found primarily in Southeast Asia. Rhabdophis is often thought of as completely harmless, but there are several cases of severe envenomation and at least one recorded fatality from the Japanese species. The symptoms have been compared to those of highly venomous African colubrids such as the Boomslang. Similar reports exist for other species of the genus, which also make reference to the highly hemorrhagic nature of the venom. There is a supposed antivenom in Japan, but not in other countries.

The king cobra (Ophiophagus hannah) is a species of venomous elapid snake endemic to jungles in Southern and Southeast Asia. The sole member of the genus Ophiophagus, it is distinguishable from other cobras, most noticeably by its size and neck patterns. The king cobra is the world's longest venomous snake, with an average length of 3.18 to 4 m (10.4 to 13.1 ft), reaching a maximum of 5.85 m (19.2 ft). Its skin colour varies across the habitats, from black with white stripes to unbroken brownish grey. It preys chiefly on other snakes, including its own species. Unlike other snakes, it rarely hunts other vertebrates, such as rodents and lizards. Like most cobras and mambas, the king cobra's threat display includes spreading its neck-flap, raising its head upright, puffing, and hissing. Despite its fearsome reputation, the king cobra avoids confrontation with humans whenever possible. When provoked, however, it is capable of striking a target at long range and well above the ground. Rather than biting and retreating, it may sustain its bite and inject a large quantity of venom, which is a medical emergency. (Source: Wikipedia.org, CC BY-SA)
Kirtland's snake (Clonophis kirtlandii) is a threatened or endangered (depending on location) North American species of nonvenomous snake of the subfamily Natricinae, of the family Colubridae. It is the only species in the genus Clonophis. Kirtland's snake is small and slender. Adults reach a total length (including tail) of 12-18 inches (30–46 cm). It is grayish brown with a double series of large black spots down the back, and alternating smaller spots running down each side. The ventral scales are brick red with a prominent round black spot at each outer end. It has 19 rows of keeled dorsal scales at midbody, and the anal plate is divided. When alarmed C. kirtlandii flattens its entire body to a remarkable thinness, and becomes rigid. Kirtland's snake will also coil up into a disc the size of about a quarter in an attempt to hide from potential threats. If this does not succeed, it will then flee instead of fight.[citation needed] No person on record has ever been bitten by a Kirtland's snake. This species prefers intimidation, hiding, and fleeing rather than any form of fighting. (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.

Bungarus is a genus of venomous elapid snakes, the kraits ('krait' is pronounced /kraɪt/, rhyming with 'kite'), found in South and Southeast Asia. The genus Bungarus has 16 species. Kraits usually range between 1.0 and 1.5 m (3 ft 3 in and 4 ft 11 in) in total length (including tail), although specimens as large as 2.0 m (6 ft 7 in) have been observed. The banded krait (B. fasciatus) may grow as large as 2.125 m (6 ft 11.7 in). Most species of kraits are covered in smooth, glossy scales arranged in bold, striped patterns of alternating black and light-colored areas. This may serve as aposematic colouration in its habitat of grassland and scrub jungle. The scales along the dorsal ridge of the back are hexagonal. The head is slender, and the eyes have round pupils. Kraits have pronounced dorsolateral flattening, which causes them to be triangular in cross section. Kraits are ophiophagous, preying primarily upon other snakes (including venomous varieties) and are cannibalistic, feeding on other kraits. They also eat mice and small lizards. All kraits are nocturnal. They are more docile during the daylight; at night, they become very active, but are not very aggressive even when provoked. They are actually rather timid, and often hide their heads within their coiled bodies for protection. When in this posture, they sometimes whip their tails around as a type of distraction.

Podarcis muralis (common wall lizard) is a species of lizard with a large distribution in Europe and well-established introduced populations in North America, where it is also called the European wall lizard. It can grow to about 20 cm (7.9 in) in total length. The animal has shown variation in the places it has been introduced to. Fossils have been found in a cave in Greece dating to the early part of the Holocene. The common wall lizard is a small, thin lizard whose small scales are highly variable in colour and pattern. Its coloration is generally brownish or greyish, and may occasionally be tinged with green. In some individuals, the row of spots along their backs may form a line, while others may have a reticulated pattern with dark spots on the side and scattered white spots that can be blue in the shoulder region. The tail is brown, grey or rust in colour, and may also have light bars on the sides. The belly region has six rows of larger rectangular scales that are generally reddish, pink, or orangish. Common wall lizards may also have dark markings on the throat. This lizard has six distinct morphological forms which are identified by the colouration of its throat and underbelly. Three of these are pure morphs consisting only of solid colours on their scales: white, red (orange) or yellow, and three other morphs are distinguished by a combination of colours: white-yellow, white-red and yellow-red.

Uroplatus is a genus of geckos, commonly referred to as leaf-tail geckos or flat-tailed geckos, which are endemic to Madagascar and its coastal islands, such as Nosy Be. They are nocturnal, insectivorous lizards found exclusively in primary and secondary forest. Geckos of the genus Uroplatus are nocturnal and arboreal. They range in total length (including tail) from about 30 cm (12 in) for U. giganteus to 10 cm (3.9 in) for U. ebenaui. Larger species of Uroplatus are distinguished among geckos in having the largest number of marginal teeth among all living amniotes. Other rare apomorphic character states include multiple inscriptional ribs, restriction of autotomy planes, and finger-like diverticula of the lungs. All Uroplatus species have highly cryptic colouration, which acts as camouflage, most being grayish-brown to black or greenish-brown with various markings resembling tree bark. There are two variations of this camouflage: leaf form, and bark form. The leaf form is present in a number of small-bodied species. All other forms blend in well with tree bark upon which they rest during the day. Some of these tree bark forms have developed a flap of skin, running the length of the body, known as a 'dermal flap', which they lay against the tree during the day, scattering shadows, and making their outline practically invisible. These geckos bear a resemblance to geckos of the genera Phyllurus and Saltuarius of Australia. This is an example of convergent evolution. (Source: Wikipedia.org, CC BY-SA)
The leatherback sea turtle (Dermochelys coriacea), sometimes called the lute turtle or leathery turtle or simply the luth, is the largest of all living turtles and the heaviest non-crocodilian reptile, reaching lengths of up to 1.8 metres (5 ft 11 in) and weights of 500 kilograms (1,100 lb). It is the only living species in the genus Dermochelys and family Dermochelyidae. It can easily be differentiated from other modern sea turtles by its lack of a bony shell; instead, its carapace is covered by oily flesh and flexible, leather-like skin, for which it is named. Leatherback turtles have the most hydrodynamic body of any sea turtle, with a large, teardrop-shaped body. A large pair of front flippers powers the turtles through the water. Like other sea turtles, the leatherback has flattened forelimbs adapted for swimming in the open ocean. Claws are absent from both pairs of flippers. The leatherback's flippers are the largest in proportion to its body among extant sea turtles. Leatherback's front flippers can grow up to 2.7 m (8.9 ft) in large specimens, the largest flippers (even in comparison to its body) of any sea turtle. (Source: Wikipedia.org, CC BY-SA)
The leopard gecko or common leopard gecko (Eublepharis macularius) is a ground-dwelling lizard native to the rocky dry grassland and desert regions of Afghanistan, Iran, Pakistan, India, and Nepal. The leopard gecko has become a popular pet, and due to extensive captive breeding it is sometimes referred to as the first domesticated species of lizard. Leopard geckos are small lizards that derive their name from their spotted coloration. Hatchlings are on average 7 to 10 cm (2.8 to 3.9 in) in length and weigh about 2 to 5 grams. Adult females are about 18 to 20 cm (7.1 to 7.9 in) in length and weigh about 50 to 70 grams, while adult male geckos are about 20 to 28 cm (7.9 to 11.0 in) in length and weigh about 60 to 80 grams. Unlike many other geckos, but like other Eublepharids, their toes do not have adhesive lamellae, so they cannot climb smooth vertical walls. (Source: Wikipedia.org, CC BY-SA)
Gambelia is a genus of lizards, commonly known as leopard lizards, within the family Crotaphytidae. Leopard lizards are indigenous to arid environments of southwestern North America. Species in the genus Gambelia superficially resemble those of the genus Crotaphytus. However, one difference between the genera Gambelia and Crotaphytus is that leopard lizards have fracture planes in their tails, allowing the tails to break off when grasped by predators.

The leopard tortoise (Stigmochelys pardalis) is a large and attractively marked tortoise found in the savannas of eastern and southern Africa, from Sudan to the southern Cape. It is the only extant member of the genus Stigmochelys, although in the past, it was commonly placed in Geochelone. This tortoise is a grazing species that favors semiarid, thorny to grassland habitats. In both very hot and very cold weather, it may dwell in abandoned fox, jackal, or aardvark holes. The leopard tortoise does not dig other than to make nests in which to lay eggs. Given its propensity for grassland habitats, it grazes extensively upon mixed grasses. It also favors succulents and thistles. The leopard tortoise is the fourth-largest species of tortoise in the world, with typical adults reaching 40 cm (16 in) and weighing 13 kg (29 lb). Adults tend to be larger in the northern and southern ends of their range, where typical specimens weigh up to 20 kg (44 lb), and an exceptionally large tortoise may reach 70 cm (28 in) and weigh 40 kg (88 lb).

Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as 'legless lizards'), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling Draco lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with brightly colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals as big as water buffalo. (Source: Wikipedia.org, CC BY-SA)
Sanzinia madagascariensis, also known as the Malagasy tree boa or Madagascar tree boa, is a boa species endemic to the island of Madagascar. It was considered conspecific with the Nosy Komba ground boa. Like all other boas, it is non-venomous. Adults average 4–5 feet (122–152 cm) in length, although 6–7 foot (183–213 cm) specimens are not uncommon. Thermoreceptive pits are located between the labial scales. Females are larger than males. It is greenish in colour and is found on the east side of Madagascar. (Source: Wikipedia.org, CC BY-SA)
Mambas are fast moving highly venomous snakes of the genus Dendroaspis (which literally means 'tree asp') in the family Elapidae. Four extant species are recognised currently; three of those four species are essentially arboreal and green in colour, whereas the black mamba, Dendroaspis polylepis, is largely terrestrial and generally brown or grey in colour. All are native to various regions in sub-Saharan Africa and all are feared throughout their ranges, especially the black mamba. In Africa there are many legends and stories about mambas. The three green species of mambas are arboreal, whereas the black mamba is largely terrestrial. The black mamba is one of the largest and most venomous snakes in Africa. All four species are active diurnal hunters, preying on birds, lizards, and small mammals. At nightfall some species, especially the terrestrial black mamba, shelter in a lair. A mamba may retain the same lair for years. Stories of black mambas that chase and attack humans are common, but in fact the snakes generally avoid contact with humans. Most apparent cases of pursuit probably are examples of where witnesses have mistaken the snake's attempt to retreat to its lair when a human happens to be in the way. The black mamba usually uses its speed to escape from threats, and humans actually are their main predators, rather than prey. (Source: Wikipedia.org, CC BY-SA)
Boiga dendrophila, commonly called the mangrove snake or the gold-ringed cat snake, is a species of rear-fanged venomous snake in the family Colubridae. The species is endemic to southeast Asia. It is one of the biggest cat snake species, averaging 6–7 feet (1.8–2.1 m) in length. It is considered mildly venomous. Although moderate envenomations resulting in intense swelling have been reported, there has never been a confirmed fatality. B. dendrophila has the following characteristics: Snout longer than eye; rostral broader than deep, visible from above; internasals as long as or shorter than the prae-frontals; frontal as long as or slightly shorter than its distance from the tip of the snout; loreal at least as long as deep; a praeocular extending to the upper surface of the head, not reaching the frontal; two postoculars; temporals 2 + 2 or 2 + 3; eight (nine) upper labials, third to fifth entering the eye; four or five lower labials in contact with the anterior chin-shields; latter as long as or longer than the posterior; anterior palatine teeth not much larger than the posterior. Scales in 21 (23) rows, vertebral row enlarged; ventrals 209–239; anal entire; subcaudals 89. Black above, with yellow transverse bands, continuous or not extending across the back; labials yellow, with black edges. Lower surface black or bluish, uniform or speckled with yellow; throat yellow. Total length (including tail) 231 cm (7 ft 7 in). (Source: Wikipedia.org, CC BY-SA)
