Of the four living groups of reptiles, only one, the snakes and lizards is represented in Britain. Reptiles bodies are covered with scales. Lizards periodically shed their skins in flakes, while snakes cast off theirs as a single slough.


Which Types of Reptiles Live in Britain?

Our native reptiles include three lizard and three snake species. The common or viviparous lizard is widespread in Britain, and occurs on mountain slopes, woodland glades, and waste ground (especially where spiders - its principal food -
are found). In contrast, the more brightly coloured sand lizard is found only in a few isolated localities in southern England with a remnant population in coastal Lancashire.

Illustration of a Slow WormThe slow worm is a lizard which has evolved into a legless form with the development of a burrowing habit. Though widespread, it is seldom seen due to its burrowing and rather secretive habits. Although it favours dry country, it is found in a variety of moist micro-habitats in heathland, hedgerows and secluded country gardens.

The grass snake is our largest snake and is widespread in England and Wales. It is more commonly found near water where it hunts amphibians and fish. The adder, our only venomous snake and also the most common, is found in woodland, moorland, and mountain slopes from Land's End to northernmost regions of Scotland.
