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.
Salamanders live in rivers, swamps, forests and caves. Some spend their entire lives in water, while others migrate between water and soil for seasonal events like spawning. Different species of salamanders have varying habitat needs in captivity or in the wild, but all salamanders require moist environments to keep their skin from drying out. Active at night, they seek out cool and dark places to hide during the day.
