List of mammals of Vietnam

Sirenia is an order of fully aquatic, herbivorous mammals that live in rivers and marine wetlands.

It includes four extant species, three manatees and the dugong, and the extinct Stellar's sea cow.

Shrews and solenodons resemble mice, hedgehogs carry spines, gymnures look more like large rats, while 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.
