Looking at Amphibians
Amphibians have a long name that you can say this way: am-fib-e-un. These animals are cold-blooded and spend a lot of time in the water, but are able to spend time on land, too. One type of amphibian that you have probably held or seen up close is a frog or a toad. Animals like these don't breathe the way people do. Instead, they are able to breathe through their skin.
Water is very important for amphibians. Even though they can come up on land, most amphibians can't stay away from the water for a very long time. Besides some frogs that live in tropical areas, places where there is lot of moisture in the air, amphibians need water to reproduce. Unlike
mammals, amphibians lay their eggs in water where the eggs stay until they hatch. The babies start their lives with gills, breathing the way
fish do, but eventually grow lungs that let them breathe.
