   thumb|250px|closeup of the head of a slow-worm __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.  slow worms are semifossorial (burrowing) lizards, spending much of the time hiding underneath objects. the skin of the varieties of slow worms is smooth with scales that do not overlap one another. like many other lizards, slow worms autotomize, meaning they have the ability to shed their tails to escape predators. the tail regrows, but remains smaller. 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 from snakes. the most important one is that they have small eyes with eyelids that blink like lizards'; this feature is not found in snakes. they may also have visible ears as do lizards, which snakes do not have. they shed their skin in patches like other lizards, rather than the whole skin as most snakes do. slow worms also shed tails (autotomy) by breaking one of their tail vertebrae in half, as a defence mechanism, as lizards do. also, the pattern of their ventral scales is totally differ
