About the common slow worm
The common slow worm (Anguis fragilis) is a non-venomous species of legless lizard native to Europe. It is also called a deaf adder, blindworm, or regionally, a long-cripple, steelworm, and hazelworm.
Despite its name, the common slow worm is neither a worm nor a snake.
Common slow worms are semifossorial (burrowing) lizards that spend much of their time hiding underneath objects. The skin of slow worms is smooth, with scales that do not overlap.
