Introduction To Antarctic Animals
Antarctica is a vast frozen continent at the far south of the world. It is covered in a thick layer of ice, and surrounded by the icy waters of the Southern Ocean.
The Antarctic region includes the continent of Antarctica, together with the surrounding sea, ice shelves and island territories that fall within the Antarctic Convergence – an area where the cold Antarctic seas meet the warmer subantarctic waters.
This list of Antarctic animals contains species found throughout the Antarctic region.
The Antarctic is a cold, inhospitable place. It has a low biodiversity, which means that, compared to other parts of the world, only a small number of species are found here.
On the continent of Antarctica itself, very little life exists in the frozen interior. Most species are found on or around the coasts, particularly on the Antarctic Peninsula; the northernmost part of Antarctica.

Life in the Antarctic is a constant struggle. Let’s meet some of the animals who call this cold polar region their home …
Antarctic Animals List
Albatross
Albatrosses are large seabirds that spend most of their lives at sea. The Wandering Albatross (Diomedea exulans), and other albatross species such as the Grey-headed albatross (Thalassarche chrysostomsa) and Black-browed albatross (Thalassarche melanophris), are found in the Antarctic region.
The Wandering Albatross has an average wingspan of 3.1 m (10.2 ft.); the largest of any bird. It spends most of its life in the air, and only lands in order to feed and to breed.
Antarctic Krill (Euphausia superba)
It may be small, but the Antarctic Krill is one of the most important animals in the Antarctic food chain. This small, shrimp-like crustacean is found in vast numbers in the Southern Ocean, forming groups called swarms which can be seen from space.
Antarctic Krill grow to around 6 cm (2.4 in). Krill is eaten by many other Antarctic animals, including whales, seals and seabirds.
The total biomass (weight) of all of the Antarctic Krill in the world is thought to be larger than that of any other species.
Antarctic midge (Belgica antarctica)
The wingless Antarctic Midge grows up to 6 mm (.25 in) in length. It is the largest land animal (i.e. one that lives purely on land, and doesn’t fly or swim) in Antarctica. It is also the only insect on mainland Antarctica.
Antarctic Springtail (Cryptopygus antarcticus)
This tiny, insect-like animal grows to only 1-2 mm in length and can survive in temperatures as low as -30°C (-22°F). It has a natural chemical antifreeze in its body to prevent it from freezing.
Antarctic Toothfish / Patagonian Toothfish
The Antarctic toothfish (Dissostichus mawsoni) is one of two species of genus Dissostichus, the other being the Patagonian toothfish (Dissostichus eleginoides). Both toothfish produce natural antifreeze proteins in their blood and tissue that allow them to live in water too cold for other species to inhabit.
Arctic tern (Sterna paradisaea)
The Arctic Tern is a small seabird with mainly white plumage, bright orange legs and bill, and a black ‘cap’.
This incredible animal travels further than any other bird in one year, and is known to cover distances of around 40,000 km (25,000 miles) each year.
The Arctic Tern breeds in the Arctic before making its way south to the Antarctic. This is why you’ll find it in our Arctic Animals List, as well as in this Antarctic Animals list.
Another tern found in the Antarctic is the Antarctic Tern (Sterna vittata).
Colossal Squid (Mesonychoteuthis hamiltoni)
The Colossal Squid is also known as the Antarctic Squid. It grows up to 14m (46 ft.) and is thought to be the world’s heaviest squid (and therefore the world’s largest invertebrate).
Giant Antarctic Octopus (Megaleledone Setebos)
The Antarctic Octopus grows to almost 1 metre (3 ft.) in length, and has special venom that doesn’t freeze at sub-zero temperatures.
Hourglass Dolphin (Lagenorhynchus cruciger)
The Hourglass Dolphin is a small dolphin that is found in Antarctic and subantarctic regions. Its black and white markings make it look like a mini orca. It is very rarely seen.
Icefish
The Icefishes are a family (Channichthyidae) of at least 16 species found in the Southern Ocean. Icefish blood is colourless because it lacks hemoglobin (the chemical that processes oxygen). It isn’t needed by the Icefish, as the cold Antarctic water contains more oxygen than warmer waters. The lack of hemoglobin makes the Icefish look white.
Imperial Shag (Leucocarbo bransfieldensis)
The Antarctic Shag lives on the Antarctic Peninsula of Antarctica, and on other islands in the Southern Ocean. It is a large bird, with a white chest and black wings and back.
Like several other shags of genus Leucocarbo, the Antarctic shag has distinctive rings of blue skin around its eyes, a feature that has given birds in this group the alternative name of “blue-eyed shags”.
Kelp gull (Larus dominicanus)
The Kelp Gull is a mid-sized gull with black / dark gray wings, white head and white chest. The species is found throughout the southern hemisphere, with one subspecies, Larus dominicanus austrinus being found in Antarctica and surrounding islands.
Marbled Rockcod (Notothenia rossii)
The marbled rockcod belongs to the family Nototheniidae, a group of fish found in the Southern Ocean, whose members are known as “notothens” or “cod icefish”.
Cod icefishes have high amounts of fat for insulation, and their bodies produce antifreeze proteins; both are adaptations for life in the cold Southern Ocean.
The Marbled Rockcod was a victim of overfishing in the 20th century, which decimated its population.
Mites
Alaskozetes antarcticus is a microscopic mite that lives on Antarctica. It eats vegetation and can survive in sub-zero temperatures.
Nematodes
Nematodes are also known as roundworms. There are many different types of nematodes, some of which have adapted to life in Antarctica.
Orca / Killer Whale (Orcinus orca)
The orca, also known as a killer whale, is a toothed whale and member of the Oceanic Dolphin Family, Delphinidae. An apex predator, the orca sits at the very top of the ocean food chain.
The diet of the orca includes seals, fish and even other whales. The species is found in all of the world’s oceans, including the Southern Ocean around Antarctica.
- You can read more about the orca on this page: Orca Facts.
Penguins
No Antarctic animals list would be complete without penguins! Penguins are a family (Spheniscidae) of flightless birds found in the Southern Hemisphere. (Only one species, the Galápagos penguin, is also found in the Northern Hemisphere).
Penguins have small, powerful wings, which they use as flippers, “flying” through the water in pursuit of krill, fish, and other prey.
Five species of penguin breed on Antarctica. These are the: Emperor penguin, Chinstrap penguin, Adélie penguin, Gentoo penguin and Macaroni penguin.
Other penguin species, such as the King Penguin and the Rockhopper Penguin, are also found on subantarctic islands near Antarctica.

Petrels
The word “petrel” appears in the names of several birds within the order Procellariiformes. All petrels are seabirds that only return to land to breed. Several petrel species are found in the Antarctic, including the Snow petrel (Pagodroma nivea), Antarctic petrel (Thalassoica antarctica), Antarctic giant petrel (Macronectes giganteus), Cape petrel (Daption capense) and Antarctic prion (Pachyptila desolata).
The snow petrel breeds exclusively in Antarctica, and breeds further south than any other bird.
Phytoplankton
Phytoplankton are microscopic plants that drift in the upper layer of the sea. They live off carbon dioxide and obtain energy by photosynthesis. They are part of the important lower level of the Antarctic food chain.
Rotifers
Rotifers are a group of over 2,000 mostly microscopic animals that together make up the phylum Rotifera. Rotifers are found in many parts of the world, and are present in Antarctic water and soil.
Seals
Several species of seal are found on Antarctica. These include the southern elephant seal – the world’s largest seal, and the Crabeater Seal – the world’s commonest seal. Other Antarctic seals include the Antarctic Fur Seal, Leopard Seal, Ross Seal and Weddell Seal.
Seals belong to a group of marine mammals known as pinnipeds. This group also contains sea lions and the walrus.
(Marine mammals are mammals that either live in the sea, or whose lifestyle is reliant on the sea.)

Spectacled Porpoise (Phocoena dioptrica)
(No image available)
The spectacled porpoise is a rarely-seen porpoise found in sub-Antarctic and Antarctic waters. Markings around its eyes appear to give the spectacled porpoise its “spectacles”.
Like many marine animals, the spectacled porpoise has a black back and white undersides. This is a form of camouflage known as “countershading” that conceals the animal from both above and below.
Skua
Skuas are seabirds found in many parts of the world. Many skuas are “kleptoparasites” – a term given to animals that steal food that has been caught by other animals. Skuas will also eat other seabirds and their chicks.
South Polar Skua (Stercorarius maccormicki)
South Polar Skuas are large, powerful birds that breed on the Antarctic coast during November and December and spend winter in warmer regions. (When it’s summer in the Southern Hemisphere, it’s winter in the Northern Hemisphere.)
Brown Skua (Stercorarius antarcticus)
The brown skua, also known as the Antarctic Skua, is a large, powerful bird that, like the other skuas, will steal food from other birds.
The brown skua breeds in Antarctic regions and migrates north during other times of the year.
Snowy Sheathbill (Chionis albus)
The Snowy Sheathbill is a pigeon-sized bird with white feathers and a pink face. It is both a scavenger and a kleptoparasite. It is the only land bird native to Antarctica that isn’t a penguin.
Tardigrades
Tardigrades, or “water bears”, are microscopic animals with eight legs. Tardigrades are known for their ability to withstand extreme conditions, and have been found on mountains and in the deep sea, as well as on Antarctica.
Whales
Whales are large marine mammals belonging to the infraorder Cetacea, which also includes dolphins and porpoises.
Whales are attracted to the cold waters of the Antarctic region by the huge swarms of Antarctic Krill (which you can read about further up this Antarctic animals list) that are present in the Southern Ocean.
Whales found in the Antarctic include: Southern right whale, Antarctic minke whale, Blue Whale, Humpback whale, Sperm whale, and the Southern Bottlenose whale.

Wilson’s storm petrel (Oceanites oceanicus)
Wilson’s storm petrel is one of the world’s commonest species of bird. Found all around the Southern Hemisphere, and in many parts of the Northern Hemisphere, it spends its life at sea, only returning to land to breed.
Other petrels found in Antarctica are the Black-bellied storm petrel (Fregetta tropica) and the Grey-backed storm petrel (Garrodia nereis).
Zooplankton
Zooplankton are animals that drift in the sea. The word “Zooplankton” is derived from the Greek words for “animal” and “drifter”. Most Zooplankton are very small, and eat microscopic plants called phytoplankton.
Zooplankton include the larvae of shrimps and crabs, and most are too small to be seen with the naked eye. However, Zooplankton also includes larger animals such as Krill and Jellyfish.
Zooplankton form an important part of the Antarctic food chain.
Antarctic Animals List Conclusion
We hope that you have enjoyed learning about the many different kinds of Antarctic animals. There are far fewer species found in the Antarctic than in other, more biodiverse, areas such as rainforests. However, the species that do manage to exist on and around this freezing continent are especially interesting, due to the special adaptations they have had to evolve.
If there is an animal on this list that you are particularly interested in, why not learn a bit more about it? You could try to find out its conservation status, if it has any special adaptations for Antarctic life, and what it eats … or what eats it!
