Spheniscus
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 An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spheniscus Humboldti
The Humboldt penguin (''Spheniscus humboldti'') is a medium-sized penguin. It resides in South America, along the Pacific Ocean, Pacific coast of Peru and Chile. Its nearest relatives are the African penguin, the Magellanic penguin and the Galápagos penguin. The Humboldt penguin and the Humboldt Current, cold water current it swims in both are named after the explorer Alexander von Humboldt. The species is listed as vulnerable by the IUCN with no population recovery plan in place. The current wild population is composed of roughly 23,800 mature individuals and is declining. It is a Migration (ecology), migrant species. Humboldt penguins nest on islands and rocky coasts, burrowing holes in guano and sometimes using Bird nest#Scrape, scrapes or caves. In South America the Humboldt penguin is found only along the Pacific coast, and the range of the Humboldt penguin overlaps that of the Magellanic penguin on the central Chilean coast. It is vagrant in Ecuador and Colombia. The Humbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

African Penguin
The African penguin (''Spheniscus demersus''), also known as Cape penguin or South African penguin, is a species of penguin confined to southern African waters. It is the only penguin found in the Old World. Like all penguins, it is flightless, with a streamlined body and wings stiffened and flattened into flippers for a marine habitat. Adults weigh an average of and are tall. The species has distinctive pink patches of skin above the eyes and a black facial mask. The body's upper parts are black and sharply delineated from the white underparts, which are spotted and marked with a black band. The African penguin is a pursuit diver and feeds primarily on fish and squid. Once extremely numerous, the African penguin is now the rarest species of penguin classified as critically endangered, with its population declining rapidly due to a combination of several threats. It is a charismatic species and is popular with tourists. Other vernacular names of the species include black-foo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spheniscus Muizoni
''Spheniscus muizoni'' is an extinct species of banded penguins that lived during the early Late Miocene in what is now Peru, South America. The species, the earliest member of the extant genus, was described in 2007 by Ursula B. Göhlich based on fossils found in the fossiliferous Pisco Formation of the Pisco Basin, southwestern Peru. Discovery and naming Fossils of ''Spheniscus muizoni'' were found by French paleontologist Christian de Muizon in sediments belonging to the Pisco Formation at the locality Cerro la Bruja in the middle of the Pisco Basin. The material is owned by the Muséum National d'Histoire Naturelle in Paris.Göhlich, 2007, p.286 The species epithet was chosen in honour of De Muizon, who has greatly contributed to the faunal descriptions of the Pisco Formation and other areas in Peru. Description The holotype material consists of a partial postcranial skeleton, subcomplete left and right coracoid, subcomplete right scapula, a subcomplete left and right ...

Spheniscus Mendiculus
The Galápagos penguin (''Spheniscus mendiculus'') is a penguin endemic to the Galápagos Islands of Ecuador. It is the only penguin found north of the equator. Most inhabit Fernandina Island and the west coast of Isabela Island. The cool waters of the Humboldt and Cromwell Currents allow it to survive despite the tropical latitude. The Galápagos penguin is one of the banded penguins, the other species of which live mostly on the coasts of Africa and mainland South America. Due to their warm environment, Galápagos penguins have developed techniques to stay cool. The feathers on their back, flippers, and head are black, and they have a white belly and a stripe looping from their eyes down to their neck and chin. Each penguin keeps only one mate, and breeds year-round. Because there is no soft areas to nest, their nests are typically in caves and crevices which also provide protection against predators and the harsh environment. The Galápagos penguin has a lifespan of 20 ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penguin
Penguins are a group of aquatic flightless birds from the family Spheniscidae () of the order Sphenisciformes (). They live almost exclusively in the Southern Hemisphere. Only one species, the Galápagos penguin, is equatorial, with a small portion of its population extending slightly north of the equator (within a quarter degree of latitude). Highly adapted for life in the ocean 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 whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey. They spend about 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 pen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spheniscus Chilensis
''Spheniscus chilensis'' is an extinct species of penguin that lived during the Late Pliocene in Chile. The first fossil record of the penguin was discovered on the coast of Antofagasta in 1980, when coastal erosion exposed the first fossilized bone. Discovery and naming ''Spheniscus chilensis'' was discovered in 1980 at the site Cuenca del Tiburón near Antofagasta, Chile, which is part of the Late Pliocene Caleta Herradura Formation. This is the only locality from which it is known to occur. The fossil remains of ''S. chilensis'' consisted of dozens of disarticulated bones from different individuals that had eroded from a nearby rock formation. The specific name "Chilensis" references Chile, the country where it was discovered. See "Spheniscus" for the etymology of the generic name. The name ''Diomedea chilensis'' Molina was published in 1782 in his ''Saggio sulla storia naturale del Chili'' (pp. 238--239). This is an available scientific name which has been construed as a s ...

Spheniscus Magellanicus
The Magellanic penguin (''Spheniscus magellanicus'') is a South American penguin, breeding in coastal Patagonia, including Argentina, Chile, and the Falkland Islands, with some migrating to Brazil and Uruguay, where they are occasionally seen as far north as Espírito Santo. Vagrants have been found in El Salvador, the Avian Island in Antarctica, Australia, and New Zealand. It is the most numerous of the ''Spheniscus'' banded penguins. Its nearest relatives are the African penguin, the Humboldt penguin, and the Galápagos penguins. The Magellanic penguin was named after Portuguese explorer Ferdinand Magellan, who spotted the birds in 1520. The species is listed as being of Least Concern by the IUCN. Description Magellanic penguins are medium-sized penguins which grow to be tall and weigh between . The males are larger than the females, and the weight of both drops while the parents raise their young. Adults have black backs and white abdomens. There are two black bands bet ...

Spheniscus Megaramphus
''Spheniscus megaramphus'' (from Greek; ''megas'', 'large', and ''ramphos'', 'beak') is an extinct species of penguin that lived during the Late Miocene (present Peru) South America. It is notable for being the largest known species of banded penguin, along with having a proportionally large beak. Taxonomy The species was described in 2003 by Marcelo Stucchi based on fossils found in the fossiliferous Pisco Formation of the Pisco Basin, southwestern Peru. At about three feet in height, ''Spheniscus megaramphus'' was significantly larger and more robust than any living banded penguin. The beak of ''S. megaramphus'' is also proportionally much larger compared to extant banded penguins; the beak of ''S. megaramphus'' exceeds the length of its cranium, whereas the Humboldt penguin's beak and cranium are roughly equal in length. ''S. megaramphus'' is one of many extinct penguin species found in the Pisco Formation, along with other extinct banded penguins such as '' S. muizoni'' and ...

Spheniscus Anglicus
''Spheniscus anglicus'' is an extinct species of banded penguin that lived during the Late Miocene in what is now Chile, South America. The species was described in 2015 by Richard D. Benson based on a fossil found in the Bahia Inglesa Formation in northern Chile. Description The holotype material consists of a fossil penguin skull, without a beak. The species is described as smaller than the emperor penguin or the king penguin, but larger than any other in the genus. Discovery and naming The only known current fossil of ''Spheniscus anglicus'' was recovered from the Bahia Inglesa Formation at an unknown date, and later sold at the 2001 Tucson Gem & Mineral Show to Mark Rasmussen, who later donated it to the Science Museum of Minnesota The Science Museum of Minnesota is a museum in Saint Paul, Minnesota, Saint Paul, Minnesota, focused on topics in technology, natural history, physical science, and mathematics education.
