The sand lizard (Lacerta agilis) is a lacertid lizard distributed across most of Europe from France and across the continent to Lake Baikal in Russia. It does not occur in European Turkey. Its distribution is often patchy. In the sand lizard's northern populations, such as in Great Britain, it is only able to survive along coastal heathlands where the sand is hot enough to incubate their eggs. Males are known for their bright colorations and aggressive behaviors when competing for females. Their mating process is unique because of its relatively short time period and because males are generally more selective with who they mate with than females. Females typically only lay a single clutch in a year. Sand lizards spend most of their time basking, foraging, or under vegetation and prefer to live in diverse habitats. Males have their own home territories that are very wide and often overlap with other males. These males compete with each other while females have smaller home territories that neighbor each other and will sometimes share habitats with each other. They can live for up to ten years and because of this relatively long lifespan, they are sometimes subject to inbreeding and producing malformed offspring. (Source: Wikipedia.org, CC BY-SA)
