Amphibians are cold-blooded animals that have backbones (vertebrates) but what sets them apart from reptiles is the fact that they don’t have scales. Amphibians are adapted to living in the water and on land. Amphibians include frogs, toads, salamanders, and many more.
Many amphibians spend time on the land and in the water while needing to stay moist in order to absorb oxygen.
Amphibians inhabit a variety of habitats that include arboreal, fossorial, freshwater, and terrestrial ecosystems.
