There are over 500 different species of salamanders, and they come in many different shapes and sizes. They're classified as amphibians because they're cold-blooded, which means they don't produce any body heat. Salamanders, like all amphibians, depend on the environment to change the temperature of their body.
Salamanders live in wet areas or near small bodies of water, like brooks or streams, because their skin must be kept moist. This is the prime environment for reproduction because salamanders lay their eggs in the water. Salamander species vary in length. Most are small, but some grow up to be five feet long. They also have long tails, round heads, slim bodies and short legs.
Salamanders have the ability to re-grow lost limbs, toes and tails. This regenerative ability allows them to survive encounters with predators without impairment. Salamanders are nocturnal creatures, meaning they are most active at night and sleep during the day. Some salamanders have tongues that are nearly ten times the length of their body. Although most species are harmless, some of them can be dangerous and even poisonous.
Salamanders are most commonly found in the Americas. In fact, the Americas have more species of salamanders than the rest of the world combined.
