Salamanders are nocturnal and come out from their hiding places during moist nights to hunt for prey. Most species eat large amounts of invertebrates such as worms, insects and snails. A few species, like spring and red salamanders, will even eat other salamanders. Salamanders are equally important as food for many other animals, such as raccoons, opossums, bears, mink, river otter, frogs and snakes. In some places they are the most abundant vertebrate animals in the forest.
