Animal environments are classified as either aquatic (water), terrestrial (land), or amphibious (water and land). Terrestrial animals require a land habitat, but do not necessarily have to live entirely on land. Some animals are partly arboreal (tree-dwelling). Terrestrial locomotion in animals is typically on legs.

Animals using mixed habitats

Amphibious and amphibiotic animals, like frogs (the order Anura), while they do require land, are separated into their own environmental classification. The majority of amphibians (class Amphibia) have an aquatic larval stage, like a tadpole, but then live as terrestrial adults, and may return to the water to mate.
