What Makes an Amphibian? Amphibians are animals that live part of their lives in water and part on land. They usually have soft, moist skin that is protected by a slippery layer of mucus. They also tend to live in moist places or near water to keep their bodies from drying out. There are three main groups of amphibians: caecilians; salamanders, newts, and mudpuppies; and frogs and toads. All amphibians:- *.Are vertebrates (which means they have abackboneorspine) *.Are ectothermic. Also known as “cold-blooded,”ectothermic animals cannot regulate their own body heat, so they depend on warmth from sunlight to become warm and active. If they get too hot, they have to find shade or aburrowto help them cool down. *.Breathe through their skin. *.Go throughmetamorphosis. Young amphibians hatch from eggs, but do not look like their parents. As they develop, their body shape changes. Hope that helped alot.
