List of Antarctica Animals

Scientists estimate that there are more than six million species of land animals living on Earth and over two million more in the oceans. The planet's continents are teeming with life, or six of the seven are, at least. With its harsh environment and limited food sources, there are only a few animals that live in Antarctica.

About Antarctica Wildlife

The southernmost of the continents, and home to the South Pole, Antarctica is perhaps the harshest climate on Earth. It is, without question, the coldest, driest and windiest of the continents. It is almost entirely covered with a thick layer of ice that averages more than a mile deep. Life is undoubtedly a continual struggle for animals that live in Antarctica.

Penguins, Penguins, and More Penguins

Think of Antarctica wildlife, and the first animals likely to come to mind are penguins. These creatures are superbly adapted to extreme Antarctic climate. The frozen continent is home to numerous types of penguins, including:

  • Emperor penguin
  • Gentoo penguin
  • Adelie penguin
  • Chinstrap penguin

The chinstrap penguin and Adelie penguin are the most numerous birds in Antarctica, with 5 million and 2.5 million breeding pairs of birds, respectively. Some of the populations do not live in Antarctica proper, but are instead found in nearby islands. Another dozen or so species of penguins live close to Antarctica in similarly harsh conditions.

Antarctic Seals

Like penguins, there are a variety of seal species that call Antarctica home, at least for part of their life cycle. These are the only large mammals on the continent. Among the types of seals are:

  • Southern elephant seal
  • Crabeater seal
  • Antarctic fur seal
  • Leopard seal
  • Ross seal
  • Weddell seal

Visiting Birds

Antarctica is too harsh for most birds to make it a year-round home, but a number of bird species are visitors for part of the year, including:

  • Albatross
  • Arctic tern
  • Imperial shag
  • Kelp gull
  • Petrels
  • South polar skua
  • Brown skua
  • Snowy sheathbill

Sea Life

A greater variety of animals can be found in the ocean surrounding Antarctica. Large animals include dolphins, whales, orcas, giant squid and dozens of types of fish. Smaller animals, like krill and other zooplankton, are plentiful.

Last but Not Least

A few other critters make Antarctica home, including some invertebrates such as mites, tardigrades, midges and nematodes. At the larger end of the scale, a small number of humans, chiefly researchers, live in Antarctica, and some of them have brought along their dogs for companionship and to do some helpful work.
