List of mammals of Réunion

This is a list of the mammal species recorded in Réunion.

[1] The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature: The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals capable of flight.

The order Cetacea includes whales, dolphins and porpoises.

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.

Rules of whale watching activities have been situated by OMAR (Observatoire Marin de la Réunion) and Globice (Groupe local d'observation et d'identification des cétacés).
