List of mammals of Romania

The lagomorphs comprise two families, Leporidae (hares and rabbits), and Ochotonidae (pikas).

They differ from rodents in a number of physical characteristics, such as having four incisors in the upper jaw rather than two.

The order Erinaceomorpha contains a single family, Erinaceidae, which comprise the hedgehogs and gymnures.

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.
