ÃŽle Aux Cochons
Île aux Cochons, or Pig Island, is an uninhabited island in the subantarctic Crozet Archipelago. With an area of it is the third largest island of the group. Administratively, it is part of the French Southern and Antarctic Lands. Description Île aux Cochons is the westernmost island of the archipelago, lying some 30 km north-west of Île des Pingouins and 15 km south-west of the Îlots des Apôtres. It is an eroded volcanic dome, scattered with inactive craters, and a coastline consisting partly of low cliffs. Introduced species include cats, rabbits and mice. The introduced pigs that gave the island its name have been eradicated. There is no human infrastructure and visits by researchers are rare. Important Bird Area The island has been identified as an Important Bird Area (IBA) by BirdLife International as a breeding site for seabirds, and notably for its large penguin populations. It held the world's largest king penguin colony, with about half a mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crozet Islands
The Crozet Islands (french: ÃŽles Crozet; or, officially, ''Archipel Crozet'') are a sub-Antarctic archipelago of small islands in the southern Indian Ocean. They form one of the five administrative districts of the French Southern and Antarctic Lands. History Discovery and early history The Crozet Islands were discovered on 24 January 1772, by the expedition of French explorer Marc-Joseph Marion du Fresne, aboard ''Le Mascarin''. His second-in-command Jules (Julien-Marie) Crozet landed on ÃŽle de la Possession, claiming the archipelago for France. The expedition continued east and landed in New Zealand, where Captain Marion and much of his crew were killed and cannibalized by Maori. Crozet survived the disaster, and successfully led the survivors back to their base in Mauritius. In 1776, Crozet met James Cook at Cape Town, at the start of Cook's third voyage. Crozet shared the charts of his ill-fated expedition, and as Cook sailed eastward, he stopped at the islands, naming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wandering Albatross
The wandering albatross, snowy albatross, white-winged albatross or goonie (''Diomedea exulans'') is a large seabird from the family Diomedeidae, which has a circumpolar range in the Southern Ocean. It was the last species of albatross to be described, and was long considered the same species as the Tristan albatross and the Antipodean albatross. A few authors still consider them all subspecies of the same species. The SACC has a proposal on the table to split this species, and BirdLife International has already split it. Together with the Amsterdam albatross, it forms the wandering albatross species complex. The wandering albatross is one of the two largest members of the genus ''Diomedea'' (the great albatrosses), being similar in size to the southern royal albatross. It is one of the largest, best known, and most studied species of bird in the world. It has the greatest known wingspan of any living bird, and is also one of the most far-ranging birds. Some individual wandering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uninhabited Islands Of France
The list of uninhabited regions includes a number of places around the globe. The list changes year over year as human beings migrate into formerly uninhabited regions, or migrate out of formerly inhabited regions. List As a group, the list of uninhabited places are called the "nonecumene". This is a special geography term which means the uninhabited area of the world. * Virtually all of the Ocean *Virtually all of Antarctica *Most of The Arctic *Most of Greenland *Most of The Sahara * Antipodes Islands * Ashmore and Cartier Islands * Bajo Nuevo Bank * Baker Island * Ball's Pyramid * Balleny Islands * Big Major Cay * Bouvet Island * Much of the interior of Brazil * Caroline Island * Clipperton Island * The semi-arid regions and deserts of Australia * Devon Island * Much of Eastern Oregon * Elephant Island * Elobey Chico * Ernst Thälmann Island * Much of Fiordland, New Zealand * Goa Island * Gough Island * Hans Island * Harmil * Hashima Island * Hatutu * Heard Island and ...

Volcanoes Of The French Southern And Antarctic Lands
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic ...

Important Bird Areas Of The Crozet Islands
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 ha ...

Islands Of The Crozet Islands
An island or isle is a piece of subcontinental land completely surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges Delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental islands and oceanic islands. There are also artificial islands (man-made islands). There are about 900,000 official islands in the world. This number consists of all the officially-reported islands of each country. The total number of islands in the world is unknown. There may be hundreds of thousands of tiny islands that are unknown and uncounted. The number of sea islands in the world is estimated to be more than 200,000. The to ...

Subantarctic Fur Seal
The subantarctic fur seal (''Arctocephalus tropicalis'') is found in the southern parts of the Indian, Pacific, and Atlantic Oceans. It was first described by Gray in 1872 from a specimen recovered in northern Australia—hence the inappropriate specific name ''tropicalis''. Description The subantarctic fur seal is medium in size compared with other fur seals. Males grow to 2m and 160 kg, whereas females are substantially smaller—1.4m and 50 kg. Both sexes are strongly sexually dimorphic, with creamy-orange chests and faces. Their bellies are more brownish. Males have a dark grey to black back, while females are a lighter grey. Pups are black at birth, but molt at about 3 months old. The snout is short and flat, and the flippers are short and broad. Subantarctic fur seals live for about 20–25 years. Distribution Subantarctic fur seals are geographically widespread. As their name implies, they generally breed in more northerly locations than the Antarctic ...

Antarctic Fur Seal
The Antarctic fur seal (''Arctocephalus gazella''), is one of eight seals in the genus '' Arctocephalus'', and one of nine fur seals in the subfamily Arctocephalinae. Despite what its name suggests, the Antarctic fur seal is mostly distributed in Subantarctic islands and its scientific name is thought to have come from the German vessel SMS Gazelle, which was the first to collect specimens of this species from Kerguelen Islands. Taxonomy Antarctic fur seals are member of the genus ''Arctocephalus''. Recently, a proposal was made to reassign this species to the resurrected genus ''Arctophoca''. Antarctic fur seals may be confused with southern otariids that share their range, like Subantarctic (''A. tropicalis''), New Zealand (''A. forsteri''), and South American fur seals (''A. australis''), and the Juan Fernandez fur seal (''A. phillippii''), as well as the South American (''Otaria flavescens'') and New Zealand sea lions (''Phocarctos hookeri'').

Southern Elephant Seal
The southern elephant seal (''Mirounga leonina'') is one of two species of elephant seals. It is the largest member of the clade Pinnipedia and the order Carnivora, as well as the largest extant marine mammal that is not a cetacean. It gets its name from its massive size and the large proboscis of the adult male, which is used to produce very loud roars, especially during the breeding season. A bull southern elephant seal is about 40% heavier than a male northern elephant seal (''Mirounga angustirostris''), twice as heavy as a male walrus (''Odobenus rosmarus''), and 6–7 times heavier than the largest living mostly-terrestrial carnivoran, the polar bear (''Ursus maritimus'') and the Kodiak bear (''Ursus arctos middendorffi''),. Taxonomy The southern elephant seal was one of the many species originally described by Swedish zoologist Carl Linnaeus in the landmark 1758 10th edition of his ''Systema Naturae'', where it was given the binomial name of ''Phoca leonina''.

Eaton's Pintail
Eaton's pintail (''Anas eatoni'') is a dabbling duck of the genus ''Anas''. It is also known as the southern pintail. The species is restricted to the island groups of Kerguelen and Crozet in the southern Indian Ocean. It resembles a small female northern pintail. It was named after the English explorer and naturalist Alfred Edmund Eaton. It is threatened by introduced species, particularly feral cats, which prey on it. There are two subspecies In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed.
