Slow-worm Anguis fragilis

Slow-worms are lizards, though they are often mistaken for snakes. Unlike snakes they have eyelids, a flat forked tongue and can drop their tail to escape from a predator. Slow-worms rarely bask in the open, instead preferring to hide under logs or in compost heaps. Image: Paul Kitchener (Flickr).
