This is a list of the mammal species recorded in Grenada. Of the mammal species in Grenada, one is vulnerable and one is considered extinct.
The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:
Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of near threatened and least concern categories:
Subclass: Theria.
Infraclass: Metatheria.
Order: Didelphimorphia (common opossums).
Didelphimorphia is the order of common opossums of the Western Hemisphere. Opossums probably diverged from the basic South American marsupials in the late Cretaceous or early Paleocene. They are small to medium-sized marsupials, about the size of a large house cat, with a long snout and prehensile tail.
Infraclass: Eutheria.
Order: Sirenia (manatees and dugongs).
Sirenia is an order of fully aquatic, herbivorous mammals that inhabit rivers, estuaries, coastal marine waters, swamps, and marine wetlands. All four species are endangered.
Order: Rodentia (Rodents).
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.
Order: Primates.
The order Primates includes the lemurs, monkeys, and apes, with the latter category including humans.
Order: Cingulata (armadillos).
The armadillos are small mammals with a bony armored shell. There are around 20 extant species. They are native to the Americas. There are around 20 extant species.
Order: Lagomorpha (rabbits and hares).
The lagomorphs comprise two families, Leporidae (hares and rabbits), and Ochotonidae (pikas). Though they can resemble rodents, and were classified as a superfamily in that order until the early 20th century, they have since been considered a separate order. They differ from rodents in a number of physical characteristics, such as having four incisors in the upper jaw rather than two.
Order: Chiroptera (bats).
The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals capable of flight. Bat species account for about 20% of all mammals.
Order: Cetacea (whales).
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.
Order: Carnivora (carnivorans).
There are over 260 species of carnivorans, the majority of which feed primarily on meat. They have a characteristic skull shape and dentition.
