Their common English name derives from their elongated flexible snout, which is vaguely similar to the trunk of an elephant (to whom they are distantly related) and their resemblance to the true shrews.
The hyraxes are any of four species of fairly small, thickset, herbivorous mammals in the order Hyracoidea.
The order Primates contains humans and their closest relatives: lemurs, lorisoids, tarsiers, monkeys, and apes.
The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals capable of flight.
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.
