The lagomorphs comprise two families, Leporidae (hares and rabbits), and Ochotonidae (pikas).
There are over 260 species of carnivorans, the majority of which eat meat as their primary dietary item.
Walruses are the only local pinniped species to commonly consume warm-blooded prey.
There are about 220 noncetacean artiodactyl species, including many that are of great economic importance to humans.
They are the mammals most fully adapted to aquatic life with a spindle-shaped nearly hairless body, protected by a thick layer of blubber, and forelimbs and tail modified to provide propulsion underwater.
