Reptiles

The adder (Vipera berus) is the UK’s only venomous snake. However, their secretive nature and camouflaged markings mean they often go unnoticed.

The common lizard is most frequently seen on commons, heaths, moorland, dry stone walls, embankments and sea cliffs around the British Isles.

Grass snakes (Natrix natrix) are found throughout England and Wales. Feeding primarily on fish and amphibians.

These spectacular reptiles are seasonal visitors to UK seas, migrating from their tropical nesting beaches.

Due to vast habitat loss the sand lizards (Lacerta agilis) now only occurs naturally in Surrey, Dorset, Hampshire and Merseyside. 

The slow-worm (Anguis fragilis) is often found in gardens and is widespread throughout the British Isles; it is naturally absent from Ireland.

The smooth snake (Coronella austriaca) is Britain's rarest reptile, found only on heathlands in Dorset and Hampshire and on one or two heaths in Surrey and West Sussex.
