Upper surfaces are beige, light brown or olive brown sometimes with darker blotches, underneath it is white or cream and variably spotted. Long head with pointed nose with a dark brown band that becomes progressively broader as it runs back from the nose through the eye. Eyes have large horizontal pupils and the rear legs have darker horizontal bands.

It is found in all regions of France where there is water, which it seldom moves far from, making existing habitat conservation where its presence is known extremely important. Diet is mainly earth worms, small slugs and insects. It can be active around dawn and dusk but during hotter weather it tends to be nocturnal. The male has no voice sacs and the females chant is rather subdued. Hibernation takes place from October until the end of January, but is not the same for the two sexes, males spend the winter in the silt at the bottom of pools, females seek out a hole in the ground or some other cavity on land. When in danger it is capable of leaping as far as two metres.

The fact that it can be found in almost all of the regions of France has a tendency to be misleading as populations are localised and often numerically weak. Overall decline, particularly in the north of its range. Berne convention, Annexe 2. Habitats directive, Annexe 4. National protection, Art.1.
