List of mammals of the U.S. Virgin Islands

This is a list of the mammal species recorded in the U.S. Virgin Islands. Of the native mammal species in the U.S. Virgin Islands, two are vulnerable and one species has been classified as extinct.[1]

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

EXExtinctNo reasonable doubt that the last individual has died.
EWExtinct in the wildKnown only to survive in captivity or as a naturalized populations well outside its previous range.
CRCritically endangeredThe species is in imminent risk of extinction in the wild.
ENEndangeredThe species is facing an extremely high risk of extinction in the wild.
VUVulnerableThe species is facing a high risk of extinction in the wild.
NTNear threatenedThe 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.
LCLeast concernThere are no current identifiable risks to the species.
DDData deficientThere 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/cdLower risk/conservation dependentSpecies which were the focus of conservation programmes and may have moved into a higher risk category if that programme was discontinued.
LR/ntLower risk/near threatenedSpecies which are close to being classified as vulnerable but are not the subject of conservation programmes.
LR/lcLower risk/least concernSpecies for which there are no identifiable risks.

Subclass: Theria

Order: Sirenia (manatees and dugongs)
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)

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: 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.

Humpback whale
Pygmy sperm whale
Spinner dolphins
Orcas

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. The order Carnivora is represented in the U.S. Virgin Islands by an introduced species, the small Asian mongoose (Herpestes javanicus), also known as the Indian mongoose, small Indian mongoose, or the Javan mongoose, which is a species of mongoose found in the wild in South and Southeast Asia. It has been introduced to various parts of the world, including the Caribbean. In addition, the Caribbean monk seal frequently hauled out on many of the islands, but is now classified as extinct.

Notes
  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.
