Kloa Point
Kloa Point is a prominent coastal point projecting from the east side of Edward VIII Plateau, north of Cape Gotley, Antarctica. It was mapped by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition, 1936–37, and called by them Kloa ('claw'). Important Bird Area A 289 ha site on fast ice off the southern shore of the point has been designated an Important Bird Area (IBA) by BirdLife International because it supports about 3,300 breeding pairs of emperor penguins (''Aptenodytes forsteri''), based on 2009 satellite imagery. Other birds observed in the vicinity of Kloa Point include the Adélie penguin (''Pygoscelis adeliae''), Antarctic tern (''Sterna vittata''), South polar skua (''Stercorarius maccormicki''), Southern fulmar (''Fulmarus glacialoides''), Snow petrel (''Pagodroma nivea''), Weddell seal (''Leptonychotes weddellii''), and Wilson's storm petrel Wilson's storm petrel (''Oceanites oceanicus''), also known as Wilson's petre ...

Penguin In Antarctica Jumping Out Of The Water
Penguins (order Sphenisciformes , family Spheniscidae ) are a group of aquatic flightless birds. They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator. Highly adapted for life in the water, penguins have countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch with their bills and swallow it whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey. They spend roughly half of their lives on land and the other half in the sea. The largest living species is the emperor penguin (''Aptenodytes forsteri''): on average, adults are about tall and weigh . The smallest penguin species is the little blue penguin (''Eudyptula minor''), also known as the fairy penguin, which stands around tall and weighs . Today, larger penguins generally inhabit colder regions, and smaller penguins inh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctic Tern
The Antarctic tern (''Sterna vittata'') is a seabird in the family Laridae. It ranges throughout the southern oceans and is found on small islands around Antarctica as well as on the shores of the mainland. Its diet consists primarily of small fish and crustaceans. It is very similar in appearance to the closely related Arctic tern, but it is stockier, and it is in its breeding plumage in the southern summer, when the Arctic tern has shed old feathers to get its non-breeding plumage. The Antarctic tern does not migrate like the Arctic tern does, but it can still be found on a very large range. This tern species is actually more closely related to the South American tern. Gulls, skuas and jaegers are the primary predators of the bird's eggs and young. The Antarctic tern can be further divided into six subspecies. The total global population of this bird is around 140,000 individuals. Taxonomy The Antarctic tern was formally described in 1789 by the German naturalist Johann Fri ...

Important Bird Areas Of Antarctica
Importance is a property of entities that matter or make a difference. For example, World War II was an important event and Albert Einstein was an important person because of how they affected the world. There are disagreements in the academic literature about what type of difference is required. According to the causal impact view, something is important if it has a big causal impact on the world. This view is rejected by various theorists, who insist that an additional aspect is required: that the impact in question makes a value difference. This is often understood in terms of how the important thing affects the well-being of people. So on this view, World War II was important, not just because it brought about many wide-ranging changes but because these changes had severe negative impacts on the well-being of the people involved. The difference in question is usually understood counterfactually as the contrast between how the world actually is and how the world would have bee ...

Wilson's Storm Petrel
Wilson's storm petrel (''Oceanites oceanicus''), also known as Wilson's petrel, is a small seabird of the austral storm petrel family Oceanitidae. It is one of the most abundant bird species in the world and has a circumpolar distribution mainly in the seas of the southern hemisphere but extending northwards during the summer of the northern hemisphere. The world population was estimated in 2022 as stable at 8 to 20 million birds. In 2010 it had been estimated at 12-30 million. A 1998 book had estimated more than 50 million pairs. The name commemorates the Scottish-American ornithologist Alexander Wilson. The genus name ''Oceanites'' refers to the mythical Oceanids, the three thousand daughters of Tethys. The species name is from Latin ''oceanus'', "ocean". Taxonomy Originally described in the genus ''Procellaria'' it has been placed under the genus ''Oceanites''. Two or three subspecies are recognized and one population ''maorianus'' from New Zealand may be extinct. The nomin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weddell Seal
The Weddell seal (''Leptonychotes weddellii'') is a relatively large and abundant true seal with a circumpolar distribution surrounding Antarctica. The Weddell seal was discovered and named in the 1820s during expeditions led by British sealing captain James Weddell to the area of the Southern Ocean now known as the Weddell Sea. The life history of this species is well documented since it occupies fast ice environments close to the Antarctic continent and often adjacent to Antarctic bases. This is the only species in the genus ''Leptonychotes''. Description Weddell seals measure about 2.5–3.5 m (8 ft 2 in–11 ft 6 in) long and weigh 400–600 kg (880–1,320 lb). They are amongst the largest seals, with a rather bulky body and short fore flippers relative to their body length. Males weigh less than females, usually about 500 kg (1,100 lb) or less. Male and female Weddell seals are generally about the same length, though females can be slightly l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Petrel
The snow petrel (''Pagodroma nivea'') is the only member of the genus ''Pagodroma.'' It is one of only three birds that has been seen at the Geographic South Pole, along with the Antarctic petrel and the south polar skua, which have the most southerly breeding sites of any bird, inland in Antarctica. Taxonomy The snow petrel was described in 1777 by the German naturalist Georg Forster in his book ''A Voyage Round the World''. He had accompanied James Cook on Cook's second voyage to the Pacific. We particularly observed a petrel, about the size of a pigeon, entirely white, with a black bill and blueish feet; it constantly appeared about the icy masses, and may be looked upon as a sure fore-runner of ice. Forster placed the snow petrel in the genus ''Procellaria'' that had been erected for the petrels by Carl Linnaeus in 1758 and coined the binomial name ''Procellaria nivea''. The snow petrel is now the only species placed in the genus ''Pagodroma'' that was introduced for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Fulmar
The southern fulmar (''Fulmarus glacialoides'') is a seabird of the Southern Hemisphere. Along with the northern fulmar, ''F. glacialis'', it belongs to the fulmar genus ''Fulmarus'' in the family Procellariidae, the true petrels. It is also known as the Antarctic fulmar or silver-grey fulmar. It is largely pale grey above and white below with a distinctive white patch on the wing. It breeds on the coast of Antarctica and on surrounding islands, moving north in winter. It nests in colonies on cliffs, laying a single egg on a ledge or crevice. Its diet includes krill, fish and squid picked from the water's surface. Taxonomy The southern fulmar formally described and illustrated in 1840 by the Scottish zoologist Andrew Smith in his major work ''Illustrations of the Zoology of South Africa''. He placed it with all the other petrels in the genus ''Procellaria'' and coined the binomial name ''Procellaria glacialoides''. The southern fulmar is now placed with the northern fulmar in ...

South Polar Skua
The south polar skua (''Stercorarius maccormicki'') is a large seabird in the skua family, Stercorariidae. An older name for the bird is MacCormick's skua, after explorer and naval surgeon Robert McCormick, who first collected the type specimen. This species and the other large skuas, such as the great skua, are sometimes placed in a separate genus ''Catharacta''. Description The south polar skua is a large bird (though small compared to other skuas sometimes placed in ''Catharacta'') that measures around in length. Adults are greyish brown above, and have a whitish (pale morph) or straw-brown (intermediate morph) head and underparts, and the contrast between head and body makes it easy to separate from similar species with good views. Juveniles and adult dark morphs are harder to distinguish from their relatives, and more subjective or difficult-to-observe criteria, such as the colder brown plumage and blue bill base, must be used. Identification Distinguishing this skua from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adélie Penguin
The Adélie penguin (''Pygoscelis adeliae'') is a species of penguin common along the entire coast of the Antarctic continent, which is the only place where it is found. It is the most widespread penguin species, and, along with the emperor penguin, is the most southerly distributed of all penguins. It is named after Adélie Land, in turn named for Adèle Dumont d'Urville, who was married to French explorer Jules Dumont d'Urville, who first discovered this penguin in 1840. Adélie penguins obtain their food by both predation and foraging, with a diet of mainly krill and fish. Taxonomy and systematics The first Adélie penguin specimens were collected by crew members of French explorer Jules Dumont d'Urville on his expedition to Antarctica in the late 1830s and early 1840s. Jacques Bernard Hombron and Honoré Jacquinot, two French surgeons who doubled as naturalists on the journey, described the bird for science in 1841, giving it the scientific name ''Catarrhactes adelià ...

Edward VIII Plateau
The Edward VIII Plateau is a dome-shaped, ice-covered peninsula between Magnet Bay and Edward VIII Bay in Antarctica. It was probably seen by personnel on the RSS ''William Scoresby'' in 1936, and mapped from aerial photos taken by the Lars Christensen Expedition, 1936-37, and named Gulfplataet (the gulf plateau). It was renamed "King Edward Plateau" by ANCA, but the form Edward VIII Plateau has been approved by the Advisory Committee on Antarctic Names (US-ACAN) to be consistent with the names of nearby Edward VIII Bay and Ice Shelf An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The ....

Emperor Penguin
The emperor penguin (''Aptenodytes forsteri'') is the tallest and heaviest of all living penguin species and is endemic to Antarctica. The male and female are similar in plumage and size, reaching in length and weighing from . Feathers of the head and back are black and sharply delineated from the white belly, pale-yellow breast and bright-yellow ear patches. Like all penguins, it is flightless, with a streamlined body, and wings stiffened and flattened into flippers for a marine habitat. Its diet consists primarily of fish, but also includes crustaceans, such as krill, and cephalopods, such as squid. While hunting, the species can remain submerged around 20 minutes, diving to a depth of . It has several adaptations to facilitate this, including an unusually structured haemoglobin to allow it to function at low oxygen levels, solid bones to reduce barotrauma, and the ability to reduce its metabolism and shut down non-essential organ functions. The only penguin species t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
