List of mammals of Grenada

Summary

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.[1]

The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:

EX Extinct No reasonable doubt that the last individual has died.
EW Extinct in the wild Known only to survive in captivity or as a naturalized populations well outside its previous range.
CR Critically endangered The species is in imminent risk of extinction in the wild.
EN Endangered The species is facing an extremely high risk of extinction in the wild.
VU Vulnerable The species is facing a high risk of extinction in the wild.
NT Near threatened The species does not meet any of the criteria that would categorise it as risking extinction but it is likely to do so in the future.
LC Least concern There are no current identifiable risks to the species.
DD Data deficient There is inadequate information to make an assessment of the risks to this species.

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:

LR/cd Lower risk/conservation dependent Species which were the focus of conservation programmes and may have moved into a higher risk category if that programme was discontinued.
LR/nt Lower risk/near threatened Species which are close to being classified as vulnerable but are not the subject of conservation programmes.
LR/lc Lower risk/least concern Species for which there are no identifiable risks.

Subclass: Theria edit

Infraclass: Metatheria edit

Order: Didelphimorphia (common opossums) edit

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 edit

Order: Sirenia (manatees and dugongs) edit

 
West Indian manatees

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) edit

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 edit

The order Primates includes the lemurs, monkeys, and apes, with the latter category including humans.

Order: Cingulata (armadillos) edit

 
Nine-banded armadillo

The armadillos are small mammals with a bony armored shell. There are around 20 extant species. They are native to the Americas.

Order: Lagomorpha (rabbits and hares) edit

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) edit

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) edit

 
Bryde's whale

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) edit

There are over 260 species of carnivorans, the majority of which feed primarily on meat. They have a characteristic skull shape and dentition.

Notes edit

  1. ^ This list is derived from the IUCN Red List which lists species of mammals and includes those mammals that have recently been classified as extinct (since 1500 AD). The taxonomy and naming of the individual species is based on those used in existing Wikipedia articles as of 21 May 2007 and supplemented by the common names and taxonomy from the IUCN, Smithsonian Institution, or University of Michigan where no Wikipedia article was available.
