Melbourne Island
Qikiqtaryuaq, formerly Melbourne Island, is an island located in the Kitikmeot Region, Nunavut, Canada. It lies at the western end of Queen Maud Gulf and is dominated by lakes and marshlands. The island has a total area of and is uninhabited. Qikiqtaryuaq is made up of several small islands, including Kiillinnguyaq to the south and Victoria Island to the north. The region also includes numerous smaller islands that are home to a variety of wildlife such as polar bears, Arctic foxes, snow geese, walruses, seals, narwhals and beluga whales. The waters surrounding Qikiqtaryuaq are rich in fish species such as Arctic char, lake trout and whitefish. The island also serves as an important breeding ground for seabirds such as northern fulmars and kittiwakes. Inuit have inhabited the area around Qikiqtaryuaq since ancient times. They have traditionally hunted marine mammals such as seals Seals may refer to: * Pinniped, a diverse group of semi-aquatic marine mammals, many of whi ...

Northern Canada
Northern Canada, colloquially the North or the Territories, is the vast northernmost region of Canada variously defined by geography and politics. Politically, the term refers to the three Provinces_and_territories_of_Canada#Territories, territories of Canada: Yukon, Northwest Territories and Nunavut. This area covers about 48 per cent of Canada's total land area, but has less than 1 per cent of demographics of Canada, Canada's population. The terms "northern Canada" or "the North" may be used in contrast with ''the far north'', which may refer to the Canadian Arctic, the portion of Canada that lies north of the Arctic Circle, east of Alaska and west of Greenland. However, in many other uses the two areas are treated as a single unit. __TOC__ Definitions Subdivisions As a social rather than political region, the Canadian North is often subdivided into two distinct regions based on climate, the ''near north'' and the ''far north''. The different climates of these two regions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walrus
The walrus (''Odobenus rosmarus'') is a large pinniped, flippered marine mammal with a discontinuous distribution about the North Pole in the Arctic Ocean and subarctic seas of the Northern Hemisphere. The walrus is the only living species in the family (biology), family Odobenidae and genus ''Odobenus''. This species is subdivided into two subspecies: the Atlantic walrus (''O. r. rosmarus''), which lives in the Atlantic Ocean, and the Pacific walrus (''O. r. divergens''), which lives in the Pacific Ocean. Adult walrus are characterised by prominent tusks and whiskers, and their considerable bulk: adult males in the Pacific can weigh more than and, among pinnipeds, are exceeded in size only by the two species of elephant seals. Walruses live mostly in shallow waters above the continental shelves, spending significant amounts of their lives on the sea ice looking for benthic zone, benthic bivalvia, bivalve mollusks to eat. Walruses are relatively long-lived, social animals, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inuit
Inuit (; iu, ᐃᓄᐃᑦ 'the people', singular: Inuk, , dual: Inuuk, ) are a group of culturally similar indigenous peoples inhabiting the Arctic and subarctic regions of Greenland, Labrador, Quebec, Nunavut, the Northwest Territories, and Alaska. Inuit languages are part of the Eskimo–Aleut languages, also known as Inuit-Yupik-Unangan, and also as Eskaleut. Inuit Sign Language is a critically endangered language isolate used in Nunavut. Inuit live throughout most of Northern Canada in the territory of Nunavut, Nunavik in the northern third of Quebec, Nunatsiavut and NunatuKavut in Labrador, and in various parts of the Northwest Territories, particularly around the Arctic Ocean, in the Inuvialuit Settlement Region. With the exception of NunatuKavut, these areas are known, primarily by Inuit Tapiriit Kanatami, as Inuit Nunangat. In Canada, sections 25 and 35 of the Constitution Act of 1982 classify Inuit as a distinctive group of Aboriginal Canadians wh ...

Kittiwake
The kittiwakes (genus ''Rissa'') are two closely related seabird species in the gull family Laridae, the black-legged kittiwake (''Rissa tridactyla'') and the red-legged kittiwake (''Rissa brevirostris''). The epithets "black-legged" and "red-legged" are used to distinguish the two species in North America, but in Europe, where ''Rissa brevirostris'' is not found, the black-legged kittiwake is often known simply as kittiwake, or more colloquially in some areas as tickleass or tickleace. The name is derived from its call, a shrill 'kittee-wa-aaake, kitte-wa-aaake'. The genus name ''Rissa'' is from the Icelandic name ''Rita'' for the black-legged kittiwake. Description The two species are indeed physically very similar. They have a white head and body, grey back, grey wings tipped solid black and a bright yellow bill. Black-legged kittiwake adults are somewhat larger (roughly in length with a wingspan of ) than red-legged kittiwakes ( in length with a wingspan around ). Other diff ...

Northern Fulmar
The northern fulmar (''Fulmarus glacialis''), fulmar, or Arctic fulmar is a highly abundant seabird found primarily in subarctic regions of the North Atlantic and North Pacific oceans. There has been one confirmed sighting in the Southern Hemisphere, with a single bird seen south of New Zealand. Fulmars come in one of two color morphs: a light one, with white head and body and gray wings and tail, and a dark one, which is uniformly gray. Though similar in appearance to gulls, fulmars are in fact members of the family Procellariidae, which include petrels and shearwaters. The northern fulmar and its sister species, the southern fulmar (), are the extant members of the genus . The fulmars are in turn a member of the order Procellariiformes, and they all share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns; however, nostrils on albatrosses are on the sides of the bill, as opposed to the rest of the order, including fulm ...

Whitefish (fisheries Term)
Whitefish or white fish is a fisheries term for several species of demersal fish with fins, particularly Atlantic cod (''Gadus morhua''), whiting (''Merluccius bilinearis''), haddock (''Melanogrammus aeglefinus''), hake (''Urophycis''), pollock (''Pollachius''), and others. Whitefish ( Coregonidae) is also the name of several species of Atlantic freshwater fish. Whitefish live on or near the seafloor, and can be contrasted with the oily or pelagic fish which live away from the seafloor. Whitefish do not have much oil in their tissue, and have flakier white or light-coloured flesh. Most of the oil found in their bodies is concentrated in the organs, e.g. cod liver oil. Whitefish can be divided into benthopelagic fish (round fish which live ''near'' the sea bed, such as cod and coley) and benthic fish (which live ''on'' the sea bed, such as flatfish like plaice). Whitefish is sometimes eaten straight but is often used reconstituted for fishsticks, gefilte fish, lutefisk, surimi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Trout
The lake trout (''Salvelinus namaycush'') is a freshwater char living mainly in lakes in northern North America. Other names for it include mackinaw, namaycush, lake char (or charr), touladi, togue, and grey trout. In Lake Superior, it can also be variously known as siscowet, paperbelly and lean. The lake trout is prized both as a game fish and as a food fish. Those caught with dark coloration may be called ''mud hens''. Taxonomy It is the only member of the subgenus ''Cristovomer'', which is more derived than the subgenus '' Baione'' (the most basal clade of ''Salvelinus'', containing the brook trout (''S. fontinalis'') and silver trout (''S. agasizii'')) but still basal to the other members of ''Salvelinus''. Range From a zoogeographical perspective, lake trout have a relatively narrow distribution. They are native only to the northern parts of North America, principally Canada, but also Alaska and, to some extent, the northeastern United States. Lake trout have been wide ...

Arctic Char
The Arctic char or Arctic charr (''Salvelinus alpinus'') is a cold-water fish in the family Salmonidae, native to alpine lakes and arctic and subarctic coastal waters. Its distribution is Circumpolar North. It spawns in freshwater and populations can be lacustrine, riverine, or anadromous, where they return from the ocean to their fresh water birth rivers to spawn. No other freshwater fish is found as far north; it is, for instance, the only fish species in Lake Hazen which extend up to on Ellesmere Island in the Canadian Arctic. It is one of the rarest fish species in Great Britain and Ireland, found mainly in deep, cold, glacial lakes, and is at risk there from acidification. In other parts of its range, such as the Nordic countries, it is much more common, and is fished extensively. In Siberia, it is known as ''golets'' () and it has been introduced in lakes where it sometimes threatens less hardy endemic species, such as the small-mouth char and the long-finned char ...

Beluga Whale
The beluga whale () (''Delphinapterus leucas'') is an Arctic and sub-Arctic cetacean. It is one of two members of the family Monodontidae, along with the narwhal, and the only member of the genus ''Delphinapterus''. It is also known as the white whale, as it is the only cetacean to regularly occur with this colour; the sea canary, due to its high-pitched calls; and the melonhead, though that more commonly refers to the melon-headed whale, which is an oceanic dolphin. The beluga is adapted to life in the Arctic, with anatomical and physiological characteristics that differentiate it from other cetaceans. Amongst these are its all-white colour and the absence of a dorsal fin, which allows it to swim under ice with ease. It possesses a distinctive protuberance at the front of its head which houses an animal echolocation, echolocation organ called the Melon (whale), melon, which in this species is large and deformable. The beluga's body size is between that of a dolphin and a true ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narwhal
The narwhal, also known as a narwhale (''Monodon monoceros''), is a medium-sized toothed whale that possesses a large "tusk" from a protruding canine tooth. It lives year-round in the Arctic waters around Greenland, Canada and Russia. It is one of two living species of whale in the family Monodontidae, along with the beluga whale, and the only species in the genus ''Monodon''. The narwhal males are distinguished by a long, straight, helical tusk, which is an elongated upper left canine. The narwhal was one of many species described by Carl Linnaeus in his publication ''Systema Naturae'' in 1758. Like the beluga, narwhals are medium-sized whales. For both sexes, excluding the male's tusk, the total body size can range from ; the males are slightly larger than the females. The average weight of an adult narwhal is . At around 11 to 13 years old, the males become sexually mature; females become sexually mature at about 5 to 8 years old. Narwhals do not have a dorsal fin and thei ...

Pinniped
Pinnipeds (pronounced ), commonly known as seals, are a widely distributed and diverse clade of carnivorous, fin-footed, semiaquatic, mostly marine mammals. They comprise the extant families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals). There are 34 extant species of pinnipeds, and more than 50 extinct species have been described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular evidence supports them as a monophyletic lineage (descended from one ancestral line). Pinnipeds belong to the order Carnivora; their closest living relatives are musteloids (weasels, raccoons, skunks, and red pandas), having diverged about 50 million years ago. Seals range in size from the and Baikal seal to the and southern elephant seal male, which is also the largest member of the order Carnivora. Several species exh ...

Snow Goose
The snow goose (''Anser caerulescens'') is a species of goose native to North America. Both white and dark morphs exist, the latter often known as blue goose. Its name derives from the typically white plumage. The species was previously placed in the genus ''Chen'', but is now typically included in the "gray goose" genus ''Anser''. Snow geese breed north of the timberline in Greenland, Canada, Alaska, and the northeastern tip of Siberia, and spend winters in warm parts of North America from southwestern British Columbia through parts of the United States to Mexico. Snow goose populations increased dramatically in the 20th century. Taxonomy In 1750 the English naturalist George Edwards included an illustration and a description of the snow goose in the third volume of his ''A Natural History of Uncommon Birds''. He used the English name "The blue-winged goose". Edwards based his hand-coloured etching on a preserved specimen that had been brought to London from the Hudson Bay a ...
