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 hedgehogs are easily recognised by their spines, while gymnures (who are not found in Mongolia) look more like large rats.
The lagomorphs comprise two families, Leporidae (hares and rabbits), and Ochotonidae (pikas).
The shrews and solenodons closely resemble mice while the moles are stout-bodied burrowers.
