Antarctica is the most isolated continent on Earth and the only one to have almost no human habitation. [18] The most species-rich family are the snailfish (Liparidae), followed by the cod icefish (Nototheniidae)[19] and eelpouts (Zoarcidae). [60], Macrolichens (e.g., Usnea sphacelata, U. antarctica, Umbilicaria decussate, and U. aprina) and communities of weakly or non-nitrophilous lichens (e.g., Pseudephebe minuscula, Rhizocarpon superficial, and R. geographicum, and several species of Acarospora and Buellia) are relatively widespread in coastal ice-free areas. It is mostly seen in cold waters and mostly seen in Antarctica and New Zealand, however, sometimes it is also seen in areas of Africa. [70] Illegal fishing remains an issue,[21] as overfishing poses a great threat to krill and toothfish populations. [12] Invertebrates, such as beetle species, have also been introduced. It has webbed feet that are pink in color. [62] The Mount Melbourne fumarole supports the only Antarctic population of Campylopus pyriformis, which is otherwise found in Europe and South Africa. [21], Another abundant icefish group is the genus Notothenia, which like the Antarctic toothfish have antifreeze in their bodies. They might be too small for very young children to play with. [3], The non-lichenised species come from 416 different genera, representing all major fungi phyla. Comment Report abuse. It can reach a height of 2 m (6.5 ft) and is an important habitat for several smaller organisms. Skuas are brownish – grey birds and have large wings and very powerful flight. [1], Subantarctic flora is dominated by the coastal tussock grass, that can grow up to 2 metres (7 ft). However, the more stable nanoenvironments inside the rocks allow microbial populations to develop. These methods increase the bycatch of animals such as albatrosses. The famous emperor penguin is the largest species of penguins in the world and is endemic to Antarctica. [27] Crabeater seals have a population of around 15 million, making them one of the most numerous large animals on the planet. The Antarctic Treaty System is a global treaty designed to preserve Antarctica as a place of research, and measures from this system are used to regulate human activity in Antarctica. The former is small, at 16 cm (6.3 in) in diameter, while the latter can have |1 metre bell diameter and 5-metre-long tentacles. [13], The mainland of Antarctica has no macro-arthropods. Jellyfish are also found there, with 2 examples being the Ross Sea jellyfish and the cobweb jellyfish or giant Antarctic jellyfish. Also Read: Top 10 Endangered Animals In The World. The first fungi identified from the sub-antarctic islands was Peziza kerguelensis, which was described in 1847. Lichens account for 400 of these,[3] while 750 are non-lichenised. Although individual Antarctic krill are small (with a body length of around 6 cm / 2.36 in. The depth of the seafloor in this area ranges from 50 to 800 metres (164 to 2,625 ft), with an average of 500 metres (1,640 ft). The Wildlife of Antarctica’s Islands and Peninsula Known as “the great white desert,” Antarctica doesn’t provide the most hospitable environment for life forms to survive. Polar and deep-sea gigantism, where invertebrates are considerably larger than their warmer-water relatives, is common in this habitat. Many of these species are migratory, and travel to tropical waters during the Antarctic winter. [43][44] Although a few specimens of the non-native great spider crab (Hyas araneus) were captured at the South Shetland Islands in 1986, there have been no further records from the region. They migrate to the North Pacific Ocean in the winter but use the same nest throughout their lives. [29] Out of all permanent mammalian residents, the Weddell seals live the furthest south. They are sensitive to environmental changes due to the specificity of the symbiotic microbial communities within them. The largest, the elephant seal (Mirounga leonina), can reach up to 4,000 kilograms (8,818 lb), while females of the smallest, the Antarctic fur seal (Arctocephalus gazella), reach only 150 kilograms (331 lb). Talking about the appearance, it has a black head and back, however, the belly is white with pale yellow breasts and yellow ear patches. [45] Roughly 20% of the sea spider species in the world are from Antarctic waters. (H. Broch 1961). Also Read: Top 10 Animals That Mate For Life. This small, shrimp-like crustacean is found in vast numbers in the Southern Ocean, forming groups called swarms which can be seen from space. We use cookies to ensure that we give you the best experience on our website. Far more terrestrial species have been identified than marine species. Individual niches, determined by environmental factors, are filled by very few species. There are very few terrestrial invertebrates on the mainland, although the species that do live there have high population densities. Killer Whales (Orcas) The killer whale is the biggest species of dolphin, and they are also called … They live in all coastal regions of this continent and are part of large colonies that show cooperative behaviour like huddling together to escape the cold winds. These two species live north of the sea ice, and breed in harems on beaches. This initially led to fears (frequently quoted in the mainstream media) that they were invading from more northern regions because of global warming and possibly could cause serious damage to the native fauna, but more recent studies show they too are native and formerly simply had been overlooked. Crabeater seals are some of the most numerous animals found in the Antarctic with a population of over 15 million individuals. It is a small, swimming crustacean that lives in large schools, called swarms, sometimes reaching densities of 10,000–30,000 individual animals per cubic metre. The female cares for a pup for a long time and feeds it till it can dive for itself. Many species are shared with areas of the Arctic. The rising global temperatures are melting the packed ice in this region, which is where most of these animals live. The Weddell seal features a large, robust body with a small head. The Peninsula and the islands are far more habitable; some areas of the peninsula can receive 900 mm (35.4 in) of precipitation a year, including rain, and the northern Peninsula is the only area on the mainland where temperatures are expected to go above 0 °C (32 °F) in summer. The average lifespan of Emperor penguin is approximately 15 to 20 years in the wild. If strictly counting fish species of the Antarctic continental shelf and upper slope, there are more than 220 species and notothenioids dominate, both in number of species (more than 100) and biomass (more than 90%). The furthest south a lichen has been identified is 86°30'. In particular, the Antarctic seas are teeming with life, ranging from microscopic plankton to the biggest animal that ever lived on Earth, the Blue whale. Part of this system, the Convention for the Conservation of Antarctic Marine Living Resources, regulates fishing and protects marine areas.[68]. [11], Compared to other major oceans, there are few fish species in few families in the Southern Ocean. Ducks, the South Georgia pintail and Eaton's pintail, inhabit South Georgia, Kerguelen and Crozet. [48] Squid makes up most of the diet of some animals, such as grey-headed albatrosses and sperm whales, and the warty squid (Moroteuthis ingens) is one of the subantarctic's most preyed upon species by vertebrates. Some mosses and lichens however can be found even in the dry interior. Antarctica supports a complex web of life due to the nutrient-rich waters surrounding the continent. As the seafloor environment is very similar all around the Antarctic, hundreds of species can be found all the way around the mainland, which is a uniquely wide distribution for such a large community. [19][20] In addition to the relatively species-rich families, the region is home to a few species from other families: hagfish (Myxinidae), lamprey (Petromyzontidae), skates (Rajidae), pearlfish (Carapidae), morid cods (Moridae), eel cods (Muraenolepididae), gadid cods (Gadidae), horsefish (Congiopodidae), Antarctic sculpins (Bathylutichthyidae), triplefins (Tripterygiidae) and southern flounders (Achiropsettidae). These are broad-winged birds that are found on the Antarctic coast and live near the open sea. The dusky dolphin is the smallest member of the dolphin family and is only 2 metres in length. [3] Coastal algal blooms can cover up to 2 square kilometres (0.77 sq mi) of the peninsula. [3] They are highly adapted, and can be divided into three main types; crustose lichens, forming thin crusts on the surface, foliose lichens, forming leaf-like lobes, and fructicose lichens, which grow like shrubs. They live near the coastal regions and spend a lot of time in the water hunting for food. [4], The four species that inhabit sea ice are thought to make up 50% of the total biomass of the world's seals. [61] Well-adapted moss and lichen can be found in rocks throughout the continent. The subantarctic islands are a more favourable environment for plant growth than the mainland. [23][24], There are two icefish species from the genus Dissostichus, the Antarctic toothfish (D. mawsoni) and the Patagonian toothfish (D. eleginoides), which by far are the largest fish in the Southern Ocean. Terrestrial vertebrates are limited to sub-antarctic islands, and even then they are limited in number. [56][57] However, more recent observations have revealed a highly variable growth rate where individuals seemingly could lack any visible growth for decades, but another was observed to increase its size by almost 30% in only two years and one reached a weight of 76 kg (168 lb) in about 20 years or less.[57]. [34] Insects endemic to Antarctica include: Springtail species identified in recent research:[35], Mite species identified in recent research:[35], Five species of krill, small free-swimming crustaceans, are found in the Southern Ocean. Some areas receive as little as 50 mm (2.0 in) of precipitation annually. Most fungi are thought to have arrived in Antarctica via airborne currents or birds. [65] These blooms can reach about 106 cells per mL. Tens of undescribed species also occur in the region, especially among the snailfish. Animals of Antarctica Get Antarctic animal pictures (including penguins, seals, and whales) in this photo gallery from National Geographic. Do post your comments. [3] While not being as widespread as lichens, they remain ubiquitous wherever plants can grow, with Ceratodon purpureus being found as far south as 84°30' on Mount Kyffin. PUBLISHED November 16, 2009 In all these areas, 90% of the seafloor is made up of soft sediments, such as sand, mud, and gravel. The site is also to cover things that are related to the world. Plants are similarly restricted mostly to the subantarctic islands, and the western edge of the Peninsula. Additionally, they are also monogamous and stay with the same mate. To access air, Weddell seals make and maintain holes in the sea ice with their teeth. [58] The genus Thelebolus for example, arrived on birds some times ago, but have since evolved local strains. By Matt Long Published on Saturday, August 30, 2014. They lay only one egg a year and care for it very meticulously. Today, there is some evidence to support it since the remains of the colossal squid have been found in the digestive tracts of sperm whales. Lichen species identified in recent research:[35], The greatest plant diversity is found on the western edge of the Antarctic Peninsula. [12] Several thousand individuals from various mite and springtail species can be found in 1 square metre (10.8 sq ft). [12] Antarctica, including the subantarctic islands, has no natural fully terrestrial mammals, reptiles, or amphibians. [31] Orcas, which do not migrate, nonetheless regularly travel to warmer waters, possibly to relieve the stress the temperature has on their skin. Although these species hunt underwater, they breed on land or ice and spend a great deal of time there, as they have no terrestrial predators. Because of the enormous size, it is believed that they eat a big volume of large fish out there in the ocean. These are the 10 most beautiful Antarctic Animals in the world.

[12] Many invertebrates on the subantarctic islands can live in subzero temperatures without freezing, whereas those on the mainland can survive being frozen. 600 million years ago, the ancient supercontinent of Gondwana formed, incorporating the present-day continents of the Middle East, India, Africa, Australia, South America and Antarctica. [1], The bryophytes of Antarctica consist of 100 species of mosses, and about 25 species of liverworts. [28] The New Zealand sea lion (Phocarctos hookeri), one of the rarest and most localised pinnipeds, breeds almost exclusively on the subantarctic Auckland Islands, although historically it had a wider range. These penguins are also called bearded penguins or ringed penguins. Their bodies are very adept at storing energy and they can go for up to two months without any food. Some of these groups are migratory and have different feeding grounds in the summer and winter while some groups choose to remain the in the Antarctic throughout the year. Parasitic species have been found in ecological situations different from the one they are associated with elsewhere, such as infecting a different type of host. [3], Some plant communities exist around fumaroles, vents emitting steam and gas that can reach 60 °C (140 °F) at around 10 centimetres (3.9 in) below the surface. Colossal Squid is one of the species where males have a penis for reproduction. Froese, Rainer and Pauly, Daniel, eds. Human activity has however led to the introduction in some areas of foreign species, such as rats, mice, chickens, rabbits, cats, pigs, sheep, cattle, reindeer, and various fish. This is because of the extremely harsh weather conditions, almost no food and no cultivable land. Less than 2-3% of species are thought to be endemic. Around 98% of continental Antarctica is covered in ice up to 4.7 kilometres (2.9 mi) thick. [13], Mites and springtails make up most terrestrial arthropod species, although various spiders, beetles, and flies can be found. Until very recently, this whale was considered a subspecies of the common minke whale but it has slight differences in size and colouration and so has been classified as a separate species. [33], Many terrestrial earthworms and molluscs, along with micro-invertebrates, such as nematodes, tardigrades, and rotifers, are also found. [5] The continental shelf surrounding the mainland is from 60 to 240 kilometres (37 to 149 mi) wide. [21][25] The Antarctic toothfish lives close to the Antarctic mainland, whereas the Patagonian toothfish lives in the relatively warmer subantarctic waters. Read more. Antarctic Fur Seal Micro-arthropods are restricted to areas with vegetation and nutrients provided by the presence of vertebrates,[12] and where liquid water can be found. It is found in cold oceans in the north and south and migrates each year searching for food. [21][22] Antifreeze proteins are also known from Southern Ocean snailfish and eelpouts. They are hexapods and have … They share these areas with seven pinniped species. [64], A wide variety of algae are found in Antarctica, often forming the base of food webs. Everybody who has worked in Antarctic waters has been struck by the peculiar absence of crabs, lobsters, shrimps.....in shallow waters. You can find Chinstrap Penguins across the Antarctic Peninsula and in the South Shetland Islands. [58] Roughly 1150 fungi species have been identified. https://themysteriousworld.com/top-10-animals-that-lives-in-antarctica Illegal fishing also brings further risks through the use of techniques banned in regulated fishing, such as gillnetting[71] and longline fishing. At least 235 marine species are found in both Antarctica and the Arctic, ranging in size from whales and birds to small marine snails, sea cucumbers, and mud-dwelling worms. The Antarctic krill is a swimming crustacean that lives in the Southern Ocean around the continent of Antarctica. Among these are several "giants", such as the iconic epimeriids that are up to 8 cm (3.1 in) long. The oceans themselves are a more stable environment for life, both in the water column and on the seabed. Each individual is 6 centimetres (2.4 in) long and weighs over 1 gram (0.035 oz). You must also know about beautiful pink animals in the world. Although there are very few species, those that do inhabit Antarctica have high population densities. [12], The flightless penguins are almost all located in the Southern Hemisphere (the only exception is the equatorial Galapagos penguin), with the greatest concentration located on and around Antarctica. Only two flowering plants inhabit continental Antarctica, the Antarctic hair grass (Deschampsia antarctica) and the Antarctic pearlwort (Colobanthus quitensis). Some of these native mammals of Antarctica are looked at below. Antarctic animals have to adapt to extreme dryness, high exposure, and bitterly cold temperatures. In this episode we meet an unexpected array of smaller species that each have their own peculiar but no less entertaining strategies for surviving in this brutal environment. Among fish found south of the Antarctic Convergence, almost 90% of the species are endemic to the region. This is because of the extremely harsh weather conditions, almost no food and no cultivable land. They are known to choose breeding grounds close to penguin colonies because this makes it easier to find food and they are also protected from predators. This is the second most numerous species of penguins and has a population of over 11 million individuals. Due to their low nutritional value, they are normally only eaten by fish, with larger animals such as birds and marine mammals only eating them when other food is scarce. Icefish are an important food for many seabirds, seals and large fish. Unlike most bryophytes, a majority of Antarctic bryophytes do not enter a diploid sporophyte stage, instead they reproduce asexually or have sex organs on their gametophyte stage. Springtails are another interesting Antarctic creature. Some - Huddling together in large or small groups is a good way of … It is also one of the world’s amazing animals. A history of overfishing and hunting has left many species with greatly reduced numbers. In summer algal blooms can cause snow and ice to appear red, green, orange, or grey. [59] Of the non-lichenised species of fungi and closer relatives of fungi discovered, 63% are ascomycota, 23% are basidiomycota, 5% are zygomycota, and 3% are chytridiomycota. Other sea creatures include animals as big as whales and as small as krill. Antarctica is the most isolated continent on Earth and the only one to have almost no human habitation. Larger species are restricted to the sub-antarctic islands and the Antarctic Peninsula. During this time, the male survives with almost no food and the female goes out into the ocean in search of food, returning after over 2 months with plenty of food for the family. The Chinstrap Penguin is the most iconic and abundant of animals in Antarctica. [63] They have also been found deep under the ice, in Lake Whillans, part of a network of subglacial lakes that sunlight does not reach.
