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 order Erinaceomorpha contains a single family, Erinaceidae, which comprise the hedgehogs and gymnures.
The shrews and solenodons closely resemble mice while the moles are stout-bodied burrowers.
The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals capable of flight.
