The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals capable of flight.
The order Erinaceomorpha contains a single family, Erinaceidae, which comprise the hedgehogs and gymnures.
The lagomorphs comprise two families, Leporidae (hares and rabbits) and Ochotonidae (pikas).
They have two incisors in the upper and lower jaw which grow continually and must be kept short by gnawing.
The shrews and solenodons closely resemble mice, while the moles are stout-bodied burrowers.
