Did you know…?

  • It is not a snake although it looks like one: it has movable eyelids and can blink, it has external ear openings and it keeps tiny vestiges of hind legs beside the cloaca, three features no snake has.

    From European Glass Lizard

  • Its body is covered in stiff osteoderms, and a flexible groove along each side lets it expand in order to breathe and to digest large prey, which its armour would otherwise not allow.

    From European Glass Lizard

  • It eats snails, shell and all, crushing them with blunt teeth and powerful jaws, and it also preys on eggs and rodents.

    From European Glass Lizard

  • It is a legless lizard often mistaken for a snake, able to shed its tail to escape a predator as many other lizards do.

    From Slow Worm
