Carnivore, feeding on 90% toads and frogs, but also earthworms, small fish, tadpoles and salamanders. Occasionally it consumes small birds, rodents, insects and spiders.
From 2 or 3 years old, mating takes place between the end of March and May and sometimes even into the autumn. Ovoviviparous, the female births between 3 to 80 babies (usually 11 to 26) between July and September which are independent as soon as being born.
Up to 10 years in the wild.
Raccoons, skunks, red fox and lynx, as well as certain birds like buzzards, herons and crows. In water, it can also be the prey of certain fish and bullfrogs.
Least concern, populations are stable.
