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.
All plethodonid salamanders are territorial, and will fight aggressively for territory. Their preferred habitat is in moist soil or leaf litter beneath stones, rotting logs, or other debris near a permanent water source. They will sometimes make use of other animals' burrows. Their diets consist primarily of ants, beetles, sow bugs, and earthworms, but they will consume most kinds of insect.
