This is a list of the native wild mammal species recorded in Antarctica. There are 23 mammal species in Antarctica, all of which are marine. Three of these species are considered to be endangered, one to be vulnerable, eight are listed as data deficient and one has not yet been evaluated.[1] Domesticated species, such as the dogs formerly present,[2] are not included.

The following tags are used to highlight each species' conservation status as assessed by the IUCN:

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 population well outside its historic range.
CR Critically Endangered The species is in imminent danger of extinction in the wild.
EN Endangered The species is facing a very 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 qualify as being at high risk of extinction but is likely to do so in the future.
LC Least Concern The species is not currently at risk of extinction in the wild.
DD Data Deficient There is inadequate information to assess the risk of extinction for this species.
NE Not Evaluated The conservation status of the species has not been studied.

Subclass: Theria[edit]

Infraclass: Eutheria[edit]

Superorder Laurasiatheria[edit]

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. The southern elephant seal is believed to be the largest carnivoran of all time. The lobodontine seals comprise about 80% of the global biomass of pinnipeds, a reflection of the high productivity of the Southern Ocean; all have circumpolar distributions surrounding Antarctica and breed on pack ice or shore-fast ice. Antarctic fur seals and southern elephant seals, in contrast, while doing much of their feeding at the edge of the continent, breed on subantarctic islands, such as South Georgia. Warmblooded prey makes up a significant proportion of the leopard seal's diet, and is occasionally taken by Antarctic fur seals.

Order: Artiodactyla (even-toed ungulates and cetaceans)[edit]
Infraorder: Cetacea (whales, dolphins and porpoises)[edit]

The infraorder 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. Their closest extant relatives are the hippos, which are artiodactyls, from which cetaceans descended; cetaceans are thus also artiodactyls.
