Both in water and on land, the newts are largely nocturnal. In their aquatic habitats, they hide under vegetation, and on land, they use structures such as logs, rocks, or small animal burrows for cover. They feed mainly on different invertebrates, but in the water may also prey on tadpoles and smaller newts. Predators include herons and other birds, snakes such as the grass snake, and various carnivorous mammals.
