Salamanders live both in freshwater and on land. Some species spend more time in the water, while others spend more time on land, but since they are amphibians, all salamanders do require water for survival. Various salamander species can be found throughout North America, South America and Asia.
Most species of salamanders, including the common salamanders in the Plethodontidae family, live mostly in streams that run through wooded areas. They can often be found under rocks and fallen trees during the daytime. Salamanders are nocturnal, which means that they sleep during the day and are active at night.
Various species of salamanders are adapted to feeding on the prey available in their individual habitats. Larger species that spend a lot of time on land may eat small mammals, insects, earthworms and even other salamanders. Those that spend more time in the water may feed on crabs, water bugs and small fish. A particular species of salamander, known as the blackbelly salamander, feeds on the adults and young of other smaller salamander species. Even their larvae are cannibalistic, sometimes eating one another before developing into adults. Salamanders, unlike frogs, have teeth in the back of their mouths and are capable of grasping their prey rather than simply catching it on their tongues.Learn More
