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.
This article on nocturnal animals list will help you understand the insects, birds, and animals that can hunt and survive in the dark. Indeed mother nature has intrigued us in various ways. Similar to the presence of thorns in desert plants to grow in less water or arid soil, there are some bird and animal species that are adapted to remain active in the darkness as well. Such animal behavior is known as nocturnality. And nocturnal animals are those belonging to this behavioral group. Likewise, plant varieties with the flowers open during night and closed at daytime are called nocturnal plants.
