__NOTOC__ ''Anguis fragilis'', or slow worm, slow-worm or slowworm , is a limbless reptile native to Eurasia. It is also sometimes referred to as the blindworm or blind worm. (Its German name 'Blindschleiche', derived from its lustrous scales, means as much as 'blinding creeper'.) Slow worms are semifossorial (burrowing) lizards, spending much of the time hiding underneath objects. The skin of slow worms is smooth with scales that do not overlap one another. Like many other lizards, slow worms autotomize, meaning that they have the ability to shed their tails to escape predators. While the tail regrows, it does not reach its original length. They are common in gardens and can be encouraged to enter and help remove pest insects by placing black plastic or a piece of tin on the ground. On warm days, one or more slow worms will often be found underneath these heat collectors. One of the biggest causes of mortality in slow worms in suburban areas is the domestic cat, against which it has no defence. == Physical traits == These reptiles are mostly active during the twilight and occasionally bask in the sun, but are more often found hiding beneath rocks and logs. They are carnivorous and, because they feed on slugs and worms, they can often be found in long grass and other damp environments. The females give birth to live young (ovoviviparous birth). In the days leading up to birth, the female can often be seen basking in the sun on a warm road. Although these lizards are often mistaken for snakes, a number of features differentiate them. The most important one is that they have small eyes with eyelids that, like other lizards, blink. Unlike snakes, they may also have visible ears. They shed their skin in patches, whereas most snakes shed their whole skin. Slow worms may also shed their tails (autotomy) as a defence mechanism, by breaking one of their tail vertebrae in half. Also, the pattern of their ventral scales is totally different from that of snakes. 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「anguis fragilis」の詳細全文を読む スポンサード リンク
