[1] The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature: The order Erinaceomorpha contains a single family, Erinaceidae, which comprise the hedgehogs and gymnures.
The hedgehogs are easily recognised by their spines while gymnures look more like large rats.
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.
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.
