The sand lizard (''Lacerta agilis'') is a lacertid lizard distributed across most of Europe and eastwards to Mongolia. It does not occur in the Iberian peninsula or European Turkey. Its distribution is often patchy. ==Description== 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 in length. 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. They are mostly common in Poland, Czech Republic and countries around that area. They bask on rocks in the day and when it's night they go into their holes underground. To protect themselves they pop off their tail and bite the predator. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sand lizard」の詳細全文を読む スポンサード リンク
