List Of Penguins
Penguin, Penguins are birds in the Family (biology), family Spheniscidae in the Monotypic taxon, monotypic Order (biology), order Sphenisciformes. They inhabit high-productivity marine habitats, almost exclusively in the Southern Hemisphere; the only species to occur north of the Equator is the Galapagos penguin. The only group of birds other than the ratites to be entirely flightless, penguins are extremely adapted to their aquatic lifestyle, with a streamlined shape that minimizes drag, Countershading, countershaded dark-and-white plumage, dense bones, powerful flippers, and insulating feathers that allow them to withstand very low temperatures on land and in water. There are currently 18 extant species of penguins recognised by the International Ornithologists' Union, distributed among six genera. Many species of fossil penguins are known from the Paleocene onwards; however, their exact number and taxonomy are unsettled due to ongoing discoveries. Conventions Conservatio ...

George Robert Gray
George Robert Gray (8 July 1808 – 6 May 1872) was an English zoology, zoologist and author, and head of the Ornithology, ornithological section of the British Museum, now the Natural History Museum, London, Natural History Museum, London for forty-one years. He was the younger brother of the zoologist John Edward Gray and the son of the botanist Samuel Frederick Gray. George Gray's most important publication was his ''Genera of Birds'' (1844–49), illustrated by David William Mitchell and Joseph Wolf, which included 46,000 references. Biography He was bornon 8 July 1808 in Little Chelsea, London, to Samuel Frederick Gray, naturalist and pharmacologist, and Elizabeth (née Forfeit), his wife. He was educated at Merchant Taylor's School. Gray started at the British Museum as Assistant Keeper of the Zoology Branch in 1831. He began by cataloguing insects, and published an ''Entomology of Australia'' (1833) and contributed the entomogical section to an English edition of ...

Emperor Penguin
The emperor penguin (''Aptenodytes forsteri'') is the tallest and heaviest of all living penguin species and is Endemism in birds, 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 species of penguin, the emperor 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 Hemoglobin, 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 ...

Subantarctic
The sub-Antarctic zone is a physiographic region in the Southern Hemisphere, located immediately north of the Antarctic region. This translates roughly to a latitude of between 46th parallel south, 46° and 60th parallel south, 60° south of the Equator. The subantarctic region includes many List of Antarctic and subantarctic islands, islands in the southern parts of the Atlantic Ocean, Atlantic, Indian Ocean, Indian, and Pacific Ocean, Pacific oceans, especially those situated north of the Antarctic Convergence. Subantarctic glaciers are, by definition, located on islands within the subantarctic region. All glaciers located on the continent of Antarctica are by definition considered to be list of glaciers in the Antarctic, Antarctic glaciers. Geography The subantarctic region comprises two geographic zones and three distinct weather front, fronts. The northernmost boundary of the subantarctic region is the rather ill-defined subtropical front, Subtropical Front (STF), also r ...

King Penguin
The king penguin (''Aptenodytes patagonicus'') is the second largest species of penguin, smaller than but somewhat similar in appearance to the emperor penguin. King penguins mainly eat lanternfish, squid, and krill. On foraging trips, king penguins repeatedly dive to over , and have been recorded at depths greater than . Predators of the king penguin include giant petrels, skuas, the snowy sheathbill, the leopard seal, and the orca. The king penguin breeds on the subantarctic islands at the northern reaches of Antarctica, South Georgia Island, South Georgia, southern Argentina, and other temperate islands of the region. It also lives on Macquarie Island in the Southern Ocean and the Falkland Islands. This bird was exploited commercially in the past for its blubber, oil, meat, and feathers. Today it is fully protected. Taxonomy In 1778, the English illustrator John Frederick Miller included a hand-coloured engraving of the king penguin in his ''Icones animalium et plantarum''. ...

John Frederick Miller
John Frederick Miller (active 1772–1796) was an English illustrator, mainly of botanical subjects. Miller was the son of the artist Johann Sebastian Müller (1715 – c. 1790). Miller, along with his brother James, produced paintings from the sketches made by Sydney Parkinson on James Cook's first voyage. He accompanied Joseph Banks on his expedition to Iceland in 1772. Between 1776 and 1785 Miller published 60 hand-coloured engravings in his ''Icones animalium et plantarum'' or ''Various subjects of Natural History, wherein are delineated Birds, Animals and many curious Plants, &c''. Very few copies of this work survive. The plates include binomial names, some of which contain the oldest published specific epithet and therefore have priority over later scientific names. There are seven species of bird for which Miller's plate is the holotype; these include the king penguin, the secretarybird, the crested caracara and the extinct Tahiti crake. The plates were re-issued in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crested Penguin
''Eudyptes'' is a genus of penguins whose members are collectively called crested penguins. The exact number of species in the genus varies between four and eight depending on the authority, and a Chatham Islands species became extinct in recent centuries. All are black and white penguins with yellow crests, red bills and eyes, and are found on Subantarctic islands in the world's southern oceans. All lay two eggs, but raise only one young per breeding season; the first egg laid is substantially smaller than the second. Taxonomy The genus ''Eudyptes'' was introduced by the French ornithologist Louis Pierre Vieillot in 1816; the name is derived from the Ancient Greek words meaning "fine", and meaning "diver". The type species was designated as the western rockhopper penguin by George Robert Gray in 1840. The genus contains eight exant species: * Macaroni penguin, ''Eudyptes chrysolophus'' * Royal penguin, ''Eudyptes schlegeli'' * Northern rockhopper penguin, ''Eudyptes moseleyi' ...

Banded Penguin
The banded penguins are penguins that belong to the genus ''Spheniscus''. There are four living species, all with similar banded plumage-patterns. They are sometimes also known as "jack-ass penguins" due to their loud locator-calls sounding similar to a donkey braying. Common traits include a band of black that runs around their bodies bordering their black dorsal coloring, black beaks with a small vertical white band, distinct spots on their bellies, and a small patch of unfeathered or thinly feathered skin around their eyes and underdeveloped fluff sack that can be either white or pink. All members of this genus lay eggs and raise their young in nests situated in burrows or in natural depressions in the earth. Systematics Banded penguins belong to the genus ''Spheniscus'', which was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the African penguin (''Spheniscus demersus'') as the type species. The genus name ''Spheniscus'' is derived from the Anci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eudyptula
The genus ''Eudyptula'' ("good little diver") contains two species of penguin, found in southern Australia, Tasmania, and New Zealand (including the Chatham Islands). They are commonly known as the little penguin, little blue penguin, or, in Australia, fairy penguin. In the language of the Māori people of New Zealand, little penguins are known as . For many years, a white-flippered form of the little penguin found only in North Canterbury, New Zealand was considered either a separate species, '' Eudyptula albosignata'', or just a subspecies, ''Eudyptula minor albosignata''. Analysis of mtDNA revealed that ''Eudyptula'' falls instead into two groups: a western one, found along the southern coast of Australia and the Otago region of New Zealand, and another found in the rest of New Zealand. These two groups are now considered full species: ''Eudyptula novaehollandiae'' in Australia and Otago, and '' Eudyptula minor'' elsewhere. ''E. novaehollandiae'' probably arrived in New Zeal ...

Pygoscelis
The genus ''Pygoscelis'' ("rump-legged") contains three living species of penguins collectively known as "brush-tailed penguins". Taxonomy Mitochondrial and nuclear DNA evidence suggests the genus split from other penguins around 38 million years ago, about 2 million years after the ancestors of the genus '' Aptenodytes''. In turn, the Adelie penguins split off from the other members of the genus around 19 million years ago. ;Extant species A 2020 study found that the gentoo penguin may actually comprise a species complex of 4 similar but genetically distinct species: the northern gentoo penguin (''P. papua''), the southern gentoo penguin (''P. ellsworthi''), the eastern gentoo penguin (''P. taeniata''), and the newly-described South Georgia gentoo penguin (''P. poncetii''). However, in 2021 the International Ornithological Congress recognized these as being subspecies In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank b ...
