Reptiles and Amphibians in Jersey

There are four species of reptiles found in Jersey.


Grass snakes up to 100cm long can sometimes be seen in the heathland areas. Jersey is the only one of the Channel Islands to have Grass Snakes. There are no Adders in the Island.

Slow Worms

Slow Worms are legless lizards often mistaken for snakes. Unlike the grass snake it has eyelids, and like lizards it can shed its tail if caught by a predator. Slow Worms are seldom seen out on hot days as they hide under stones or leaves, coming out after dark or in damp weather to feed.


Among the dunes of Les Blanches Banques, and the sandy heathlands of Les Landes, Les Creux, Noirmont Point and Portelet Common, Green Lizards thrive, feeding on the prolific insect life. The bright green colour distinguishes this lizard from the olive green and brown Wall Lizard which is found in only three places in the Island: Gorey Castle, St Aubin's fort and Elizabeth Castle. These lizards have become used to people so it isn't too difficult to spot them, especially in the early mornings when they soak up the sun.

Frogs and Toads

The Agile Frog is common on the continent but Jersey is the only part of the British Isles where it is found. It is a threatened species in Jersey due to habitat loss and pollution. There is believed to be only one remaining site at Ouaisne Common where the frogs can still be found.

There are conservation projects to try and increase the numbers, and the Durrell Wildlife Conservation Trust have an enclosure alongside the reptile house where they breed agile frogs. You can read more about Durrell WIldlife Conservation Trust's work to save the local agile frog population here.

The Common Toad is found in Jersey alone of the Channel Islands. The Jersey-French name for a toad is Crapaud (pronounced Crap-o) and Crapaud therefore became the name given to Jersey people by the other Channel Islanders.

Common Toads gather to breed in spawning grounds during February. In 2007 they were found in some numbers on one of the beaches and many were saved from the incoming tide by walkers! They are seen mostly in the heathlands, and are common visitors to many gardens.
