Antarctic animals record, with footage and data. Uncover the wonderful animals that stay in one of many world’s harshest environments.
Introduction To Antarctic Animals
Antarctica is an enormous frozen continent on the far south of the world. It’s lined in a thick layer of ice, and surrounded by the icy waters of the Southern Ocean.
The Antarctic area contains the continent of Antarctica, along with the encircling sea, ice cabinets and island territories that fall inside the Antarctic Convergence – an space the place the chilly Antarctic seas meet the hotter subantarctic waters.
This record of Antarctic animals accommodates species discovered all through the Antarctic area.
The Antarctic is a chilly, inhospitable place. It has a low biodiversity, which implies that, in comparison with different elements of the world, solely a small variety of species are discovered right here.
On the continent of Antarctica itself, little or no life exists within the frozen inside. Most species are discovered on or across the coasts, significantly on the Antarctic Peninsula; the northernmost a part of Antarctica.
Life within the Antarctic is a continuing wrestle. Let’s meet among the animals who name this chilly polar area their dwelling …
Antarctic Animals Checklist
Albatross
Albatrosses are massive seabirds that spend most of their lives at sea. The Wandering Albatross (Diomedea exulans), and different albatross species such because the Gray-headed albatross (Thalassarche chrysostomsa) and Black-browed albatross (Thalassarche melanophris), are discovered within the Antarctic area.
The Wandering Albatross has a mean wingspan of three.1 m (10.2 ft.); the biggest of any chook. It spends most of its life within the air, and solely lands so as to feed and to breed.
Antarctic Krill (Euphausia superba)
It might be small, however the Antarctic Krill is likely one of the most necessary animals within the Antarctic meals chain. This small, shrimp-like crustacean is present in huge numbers within the Southern Ocean, forming teams referred to as swarms which will be seen from area.
Antarctic Krill develop to round 6 cm (2.4 in). Krill is eaten by many different Antarctic animals, together with whales, seals and seabirds.
The whole biomass (weight) of all the Antarctic Krill on this planet is regarded as bigger than that of another species.
Antarctic midge (Belgica antarctica)
The wingless Antarctic Midge grows as much as 6 mm (.25 in) in size. It’s the largest land animal (i.e. one which lives purely on land, and doesn’t fly or swim) in Antarctica. It is usually the one insect on mainland Antarctica.
Antarctic Springtail (Cryptopygus antarcticus)
This tiny, insect-like animal grows to solely 1-2 mm in size and may survive in temperatures as little as -30°C (-22°F). It has a pure chemical antifreeze in its physique to forestall it from freezing.
Antarctic Toothfish / Patagonian Toothfish
The Antarctic toothfish (Dissostichus mawsoni) is one in all two species of genus Dissostichus, the opposite being the Patagonian toothfish (Dissostichus eleginoides). Each toothfish produce pure antifreeze proteins of their blood and tissue that enable them to stay in water too chilly for different species to inhabit.
Arctic tern (Sterna paradisaea)
The Arctic Tern is a small seabird with primarily white plumage, brilliant orange legs and invoice, and a black ‘cap’.
This unimaginable animal travels additional than another chook in a single yr, and is thought to cowl distances of round 40,000 km (25,000 miles) every year.
The Arctic Tern breeds within the Arctic earlier than making its method south to the Antarctic. Because of this you’ll discover it in our Arctic Animals Checklist, in addition to on this Antarctic Animals record.
One other tern discovered within the Antarctic is the Antarctic Tern (Sterna vittata).
Colossal Squid (Mesonychoteuthis hamiltoni)
The Colossal Squid is also referred to as the Antarctic Squid. It grows as much as 14m (46 ft.) and is regarded as the world’s heaviest squid (and subsequently the world’s largest invertebrate).
Large Antarctic Octopus (Megaleledone Setebos)
The Antarctic Octopus grows to virtually 1 metre (3 ft.) in size, and has particular venom that doesn’t freeze at sub-zero temperatures.
Hourglass Dolphin (Lagenorhynchus cruciger)
The Hourglass Dolphin is a small dolphin that’s present in Antarctic and subantarctic areas. Its black and white markings make it appear like a mini orca. It is extremely hardly ever seen.
Icefish
The Icefishes are a household (Channichthyidae) of not less than 16 species discovered within the Southern Ocean. Icefish blood is colourless as a result of it lacks hemoglobin (the chemical that processes oxygen). It isn’t wanted by the Icefish, because the chilly Antarctic water accommodates extra oxygen than hotter waters. The dearth of hemoglobin makes the Icefish look white.
Imperial Shag (Leucocarbo bransfieldensis)
The Antarctic Shag lives on the Antarctic Peninsula of Antarctica, and on different islands within the Southern Ocean. It’s a massive chook, with a white chest and black wings and again.
Like a number of different shags of genus Leucocarbo, the Antarctic shag has distinctive rings of blue pores and skin round its eyes, a function that has given birds on this group the choice title of “blue-eyed shags”.
Kelp gull (Larus dominicanus)
The Kelp Gull is a mid-sized gull with black / darkish grey wings, white head and white chest. The species is discovered all through the southern hemisphere, with one subspecies, Larus dominicanus austrinus being present in Antarctica and surrounding islands.
Marbled Rockcod (Notothenia rossii)
The marbled rockcod belongs to the household Nototheniidae, a bunch of fish discovered within the Southern Ocean, whose members are generally known as “notothens” or “cod icefish”.
Cod icefishes have excessive quantities of fats for insulation, and their our bodies produce antifreeze proteins; each are diversifications for all times within the chilly Southern Ocean.
The Marbled Rockcod was a sufferer of overfishing within the twentieth century, which decimated its inhabitants.
Mites
Alaskozetes antarcticus is a microscopic mite that lives on Antarctica. It eats vegetation and may survive in sub-zero temperatures.
Nematodes
Nematodes are also referred to as roundworms. There are a lot of various kinds of nematodes, a few of which have tailored to life in Antarctica.
Orca / Killer Whale (Orcinus orca)
The orca, also referred to as a killer whale, is a toothed whale and member of the Oceanic Dolphin Household, Delphinidae. An apex predator, the orca sits on the very prime of the ocean meals chain.
The weight loss program of the orca contains seals, fish and even different whales. The species is present in all the world’s oceans, together with the Southern Ocean round Antarctica.

Penguins
No Antarctic animals record could be full with out penguins! Penguins are a household (Spheniscidae) of flightless birds discovered within the Southern Hemisphere. (Just one species, the Galápagos penguin, can also be discovered within the Northern Hemisphere).
Penguins have small, highly effective wings, which they use as flippers, “flying” by way of the water in pursuit of krill, fish, and different prey.
5 species of penguin breed on Antarctica. These are the: Emperor penguin, Chinstrap penguin, Adélie penguin, Gentoo penguin and Macaroni penguin.
Different penguin species, such because the King Penguin and the Rockhopper Penguin, are additionally discovered on subantarctic islands close to Antarctica.
Petrels
The phrase “petrel” seems within the names of a number of birds inside the order Procellariiformes. All petrels are seabirds that solely return to land to breed. A number of petrel species are discovered within the Antarctic, together with the Snow petrel (Pagodroma nivea), Antarctic petrel (Thalassoica antarctica), Antarctic big petrel (Macronectes giganteus), Cape petrel (Daption capense) and Antarctic prion (Pachyptila desolata).
The snow petrel breeds solely in Antarctica, and breeds additional south than another chook.
Phytoplankton
Phytoplankton are microscopic crops that drift within the higher layer of the ocean. They stay off carbon dioxide and procure power by photosynthesis. They’re a part of the necessary decrease degree of the Antarctic meals chain.
Rotifers
Rotifers are a bunch of over 2,000 largely microscopic animals that collectively make up the phylum Rotifera. Rotifers are discovered in lots of elements of the world, and are current in Antarctic water and soil.
Seals
A number of species of seal are discovered on Antarctica. These embody the southern elephant seal – the world’s largest seal, and the Crabeater Seal – the world’s commonest seal. Different Antarctic seals embody the Antarctic Fur Seal, Leopard Seal, Ross Seal and Weddell Seal.
Seals belong to a bunch of marine mammals generally known as pinnipeds. This group additionally accommodates sea lions and the walrus.
(Marine mammals are mammals that both stay within the sea, or whose way of life is reliant on the ocean.)

Spectacled Porpoise (Phocoena dioptrica)
(No picture accessible)
The spectacled porpoise is a rarely-seen porpoise present in sub-Antarctic and Antarctic waters. Markings round its eyes seem to provide the spectacled porpoise its “spectacles”.
Like many marine animals, the spectacled porpoise has a black again and white undersides. It is a type of camouflage generally known as “countershading” that conceals the animal from each above and beneath.
Skua
Skuas are seabirds discovered in lots of elements of the world. Many skuas are “kleptoparasites” – a time period given to animals that steal meals that has been caught by different animals. Skuas will even eat different seabirds and their chicks.
South Polar Skua (Stercorarius maccormicki)
South Polar Skuas are massive, highly effective birds that breed on the Antarctic coast throughout November and December and spend winter in hotter areas. (When it’s summer season within the Southern Hemisphere, it’s winter within the Northern Hemisphere.)
Brown Skua (Stercorarius antarcticus)
The brown skua, also referred to as the Antarctic Skua, is a big, highly effective chook that, like the opposite skuas, will steal meals from different birds.
The brown skua breeds in Antarctic areas and migrates north throughout different occasions of the yr.
Snowy Sheathbill (Chionis albus)
The Snowy Sheathbill is a pigeon-sized chook with white feathers and a pink face. It’s each a scavenger and a kleptoparasite. It’s the solely land chook native to Antarctica that isn’t a penguin.
Tardigrades
Tardigrades, or “water bears”, are microscopic animals with eight legs. Tardigrades are recognized for his or her potential to resist excessive situations, and have been discovered on mountains and within the deep sea, in addition to on Antarctica.
Whales
Whales are massive marine mammals belonging to the infraorder Cetacea, which additionally contains dolphins and porpoises.
Whales are interested in the chilly waters of the Antarctic area by the large swarms of Antarctic Krill (which you’ll be able to examine additional up this Antarctic animals record) which are current within the Southern Ocean.
Whales discovered within the Antarctic embody: Southern proper 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 likely one of the world’s commonest species of chook. Discovered throughout the Southern Hemisphere, and in lots of elements of the Northern Hemisphere, it spends its life at sea, solely returning to land to breed.
Different petrels present in Antarctica are the Black-bellied storm petrel (Fregetta tropica) and the Gray-backed storm petrel (Garrodia nereis).
Zooplankton
Zooplankton are animals that drift within the sea. The phrase “Zooplankton” is derived from the Greek phrases for “animal” and “drifter”. Most Zooplankton are very small, and eat microscopic crops referred to as phytoplankton.
Zooplankton embody the larvae of shrimps and crabs, and most are too small to be seen with the bare eye. Nevertheless, Zooplankton additionally contains bigger animals resembling Krill and Jellyfish.
Zooplankton kind an necessary a part of the Antarctic meals chain.
Antarctic Animals Checklist Conclusion
We hope that you’ve got loved studying in regards to the many alternative sorts of Antarctic animals. There are far fewer species discovered within the Antarctic than in different, extra biodiverse, areas resembling rainforests. Nevertheless, the species that do handle to exist on and round this freezing continent are particularly attention-grabbing, because of the particular diversifications they’ve needed to evolve.
If there may be an animal on this record that you’re significantly all for, why not be taught a bit extra about it? You would attempt to discover out its conservation standing, if it has any particular diversifications for Antarctic life, and what it eats … or what eats it!
