Three things to know
- It is a lizard rather than a snake.
- It has movable eyelids.
- Slugs and earthworms are important prey.
Habitat and range
Slow worms occupy parts of western and central Europe. Cool, sheltered woodland, grassland, heath and gardens provide places to hide under stones, vegetation and surface debris.
Appearance and adaptations
The elongated body is often coppery, grey-brown or golden. Females and juveniles commonly have darker sides and lengthwise markings. Unlike snakes, slow worms have movable eyelids.
Diet and behaviour
Slugs and earthworms are principal prey. Much time is spent beneath cover or underground, which makes the species easy to overlook. Cold weather is usually spent in sheltered winter refuges.
