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.
Fire salamanders are most active during the night and when they are out of direct light. They can grow to a size of 8 inches. Spotted Salamander. No surprise, the spotted salamander gets its name from the yellow spots that dot its dark blue or black body. In the wild, these salamanders spend most of their time underground, and they also like to hide under rocks. On average, the spotted salamander grows to a size of 6 to 7.5 inches.
