The Sand lizard
The sand lizard is a sexually-dimorphic legged lizard. In northwest Europe, both sexes are characterised by lateral and dorsal strips of ocellated (eye-shaped) markings; dark patches with pale centres. Colouration varies across their European and Russian range. Males have finer markings than females, and their flanks turn bright green during the spring mating season, fading again in the late summer. Sand lizards can reach up to 25 cm (10 in) in length.[2] It has several subspecies, the westernmost of which is Lacerta agilis agilis. In this and the other main western subspecies (L. a. argus), the dorsal stripe is thin and interrupted, or not present at all. This applies particularly to the latter subspecies, which also includes a plain red or brown-backed phase without any dorsal markings. In these two subspecies, only the flanks of the males turn green in the mating season, but in the eastern subspecies (predominantly L. a. exigua), males can be wholly green, even outside the breeding season. Most of these lizards live in Eastern Europe.There mostly common in Poland, Czech Republic and country s around that area. They bask on rocks in the day and when it s night the go in to there holes underground.To protect them selves they pop off there tail and biting the predator.
