List of mammals of the U.S. Virgin Islands

Rodentia is an order of mammals characterised by two continuously growing incisors in the upper and lower jaws which must be kept short by gnawing.

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.

In addition, the Caribbean monk seal frequently visited many of the islands, but is now classified as extinct.
