Atlantic White-sided Dolphin
The Atlantic white-sided dolphin (''Lagenorhynchus acutus'') is a distinctively coloured dolphin found in the cool to temperate waters of the North Atlantic Ocean. Description The Atlantic white-sided dolphin is a relatively small dolphin. At birth, calves measure just over a meter long; adult males grow to about , and females to about , weighing between 180–230 kg (400- 510 lb) once fully grown. Females reach sexual maturity between the ages of 6 and 12 years, and males between 7 and 11 years old. The gestation period is 11 months and lactation lasts for about 18 months — both typical figures for dolphins. Atlantic white-sided dolphins are known to live for at least 17 years. The key distinguishing feature is the dolphin's coloration—a white to pale-yellow patch is found behind the dorsal fin on both sides of the body. The white-sided dolphin's color variations are unique amongst the standard hues of white, grey, black and blue seen on other pelagic cetaceans. ...

John Edward Gray
John Edward Gray (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Celtic Sea
The Celtic Sea is the area of the Atlantic Ocean off the southern coast of Ireland bounded to the north by St George's Channel, Saint George's Channel; other limits include the Bristol Channel, the English Channel, and the Bay of Biscay, as well as adjacent portions of Wales, Cornwall, parts of Devon and Brittany. The continental shelf, which drops away sharply, delimits the southern and western boundaries. The Iroise Sea off Brittany is entirely included within it. The Isles of Scilly are an archipelago of small islands in the sea. History The Celtic Sea receives its name from the Celts, Celtic heritage of the bounding lands to the north and east. Ernest William Lyons Holt, E. W. L. Holt proposed the name at a 1921 meeting of fisheries experts from Great Britain, France, and Republic of Ireland, Ireland in Dublin. This sea's northern portion was considered part of Saint George's Channel, and the southern portion was an undifferentiated part of the "Southwest Approach ...

Lagenorhynchus Acutus 3d Scan Natural History Museum University Of Pisa C 290
''Lagenorhynchus'' is a genus of oceanic dolphins in the infraorder Cetacea, presently containing six extant species. However, there is consistent molecular evidence that the genus is polyphyletic and several of the species are likely to be moved to other genera. In addition, the extinct species '' Lagenorhynchus harmatuki'' is also classified in this genus. Etymology The name ''Lagenorhynchus'' derives from the Greek ''lagenos'' meaning "bottle" and ''rhynchus'' meaning "beak". Indeed, the "bottle-nose" is a characteristic of this genus. However, the dolphins popularly called bottlenose dolphins belong in the genus '' Tursiops''. Taxonomy There is compelling phylogenetic molecular evidence that the genus ''Lagenorhynchus'' is polyphyletic, in that it currently contains several species that are not closely related. found that white-beaked and Atlantic white-sided dolphins are phylogenetically isolated within the Delphinidae, where they are believed to be rather basal m ...

Bottlenose Dolphin
The bottlenose dolphin is a toothed whale in the genus ''Tursiops''. They are common, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. Molecular studies show the genus contains three species: the common bottlenose dolphin (''Tursiops truncatus''), the Indo-Pacific bottlenose dolphin (''Tursiops aduncus''), and Tamanend's bottlenose dolphin (''Tursiops erebennus''). Others, like the Burrunan dolphin (''Tursiops (aduncus) australis''), may be alternately considered their own species or be subspecies of ''T. aduncus''. Bottlenose dolphins inhabit warm and temperate seas worldwide, being found everywhere except for the Arctic and Antarctic Circle regions. Their name derives from the Latin ''tursio'' (dolphin) and ''truncatus'' for the truncated teeth (the type specimen was old and had worn down teeth; this is not a typical characteristic of most members of the species). Numerous investigations of bottlenose dolphin intelligence have bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harbor Porpoise
The harbour porpoise (''Phocoena phocoena'') is one of eight extant species of porpoise. It is one of the smallest species of cetacean. As its name implies, it stays close to coastal areas or river estuaries, and as such, is the most familiar porpoise to whale-watching, whale watchers. This porpoise often ventures up rivers, and has been seen hundreds of kilometres from the sea. The harbour porpoise may be Polytypic taxon, polytypic, with geographically distinct populations representing distinct races: ''P. p. phocoena'' in the North Atlantic and West Africa, ''Black sea harbour porpoise, P. p. relicta'' in the Black Sea and Sea of Azov, an unnamed population in the northwestern Pacific and ''P. p. vomerina'' in the northeastern Pacific. Taxonomy The English word porpoise comes from the French (Old French , 12th century), which is from Medieval Latin , which is a compound of ''porcus'' (pig) and (fish). The old word is probably a loan-translation of a Germanic word, compare D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long-finned Pilot Whale
The long-finned pilot whale, or pothead whale (''Globicephala melas'') is a large species of oceanic dolphin. It shares the genus ''Pilot whale, Globicephala'' with the short-finned pilot whale (''Globicephala macrorhynchus''). Long-finned pilot whales are known as such because of their unusually long pectoral fins. Taxonomy and naming Etymology Pilot whales get their name from the original belief that there was a "pilot" or lead individual in their groups.Olson, P.A. (2008).

Melon-headed Whale
The melon-headed whale (''Peponocephala electra''), also known less commonly as the electra dolphin, little killer whale, or many-toothed blackfish, is a toothed whale of the oceanic dolphin family (Delphinidae). The common name is derived from the head shape. Melon-headed whales are widely distributed throughout deep tropical and subtropical waters worldwide, but they are rarely encountered at sea. They are found near shore mostly around oceanic islands, such as Hawaii, French Polynesia, and the Philippines. Taxonomy The melon-headed whale is the only member of the genus ''Peponocephala''. First recorded from a specimen collected in Hawaiʻi in 1841, the species was originally described as a member of the dolphin family and named ''Lagenorhynchus electra'' by John Edward Gray in 1846. The melon-headed whale was later determined to be sufficiently distinct from other ''Lagenorhynchus'' species to be accorded its own genus. A member of the subfamily Globicephalinae, melon-headed w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
