The following is a list of native wild mammal species recorded in Antarctica. There are 23 mammal species in Antarctica, all of which are marine. Three are considered endangered, one is 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 ...
The largest marine algae are kelp species, which include bull kelp (Durvillaea antarctica), which can reach over 20 metres (66 ft) long and is thought to be the strongest kelp in the world. As many as 47 individual plants can live on 1 square metre (10.8 sq ft), and they can grow at 60 centimetres (24 in) a day.
Walrus live mostly in shallow waters above the continental shelves, spending significant amounts of their lives on the sea ice looking for benthic bivalve molluscs. Walruses are relatively long-lived, social animals, and are considered to be a "keystone species" in the Arctic marine regions.
Lists of mammals by region cover mammals found in different parts of the world. They are organized by continent, region, and country, and in some places by sub-national region. Most are full species lists, while those for Australia and the Caribbean have links to more specific species lists.
Most of Antarctica is covered with a thick layer of ice, with few species permanently living in the ice-covered areas. There are many species of penguins in the south polar region. Almost all animals in Antarctica find their food in the Southern Ocean surrounding the continent, and there is abundant marine life in the Southern Ocean. [2]
The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed.The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb).

Marsupials reached Australia via Antarctica during the Early Eocene, around 50 mya, shortly after Australia had split off. [n 1] [n 2] This suggests a single dispersion event of just one species, most likely a relative to South America's monito del monte (a microbiothere, the only New World australidelphian).
