Amphibians are four-legged, cold-blooded vertebrates who generally spend part of their time on land. Their skin must be kept moist, so they live close to water. Amphibians do have lungs, but are also able to "breath" through their skin. They do not have amniotic eggs. Amniotic means that the sac that the embryo is in is not filled with serous fluid.
An amphibian starts its life as an aquatic animal, breathing under water. It changes, develops legs and the ability to breathe out of the water. By that time it looks like a small version of the terrestrial/land dwelling form of the amphibian.
