This is a list of the mammal species recorded in the Falkland Islands. There are 28 mammal species in and around the Falkland Islands, of which two are endangered and two are vulnerable. The Falkland Island wolf is the only species on the islands which has gone extinct.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.

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.

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.

Family: Molossidae Genus: Tadarida Mexican free-tailed bat, T. brasiliensis

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.

Suborder: Caniformia Family: Canidae (dogs, foxes) Genus: Dusicyon Falkland Island wolf, D. australis EX Genus: Lycalopex South American grey fox, L. griseus LR/lc introduced Family: Otariidae (eared seals, sealions) Genus: Arctophoca South American fur seal, Arctophoca australis LR/lc Genus: Otaria South American sea lion, Otaria flavescens LR/lc Family: Phocidae (earless seals) Genus: Hydrurga Leopard seal, Hydrurga leptonyx LR/lc Genus: Leptonychotes Weddell seal, Leptonychotes weddellii LR/lc Genus: Lobodon Crabeater seal, Lobodon carcinophagus LR/lc Genus: Mirounga Southern elephant seal, Mirounga leonina LR/ Family: Mustelidae Genus: Lontra (otters) Marine otter, Lontra felina, EX (occasional vagrant sightings from Patagonia.)

Order: Artiodactyla (even-toed ungulates) The even-toed ungulates are ungulates whose weight is borne about equally by the third and fourth toes, rather than mostly or entirely by the third as in perissodactyls. There are about 220 artiodactyl species, including many that are of great economic importance to humans.

Family: Cervidae (deer) Subfamily: Capreolinae Genus: Rangifer Reindeer, R. tarandus introduced Family: Bovidae (bovids) Genus: Ovis Feral sheep, O. aries introduced Family: Camelidae (camelids) Genus: Lama Guanaco, L. guanicoe introduced
