Balaenoptera Physalus
''Balaenoptera'' () is a genus of rorquals containing eight extant species. ''Balaenoptera'' comprises all but two of the extant species in its family (the humpback whale and gray whale); the genus is currently polyphyletic, with the two aforementioned species being phylogenetically nested within it. This genus is known in the fossil records from the Neogene to the Quaternary (13.65 million years ago to the present). Taxonomy and systematics The genus ''Balaenoptera'' contains the following extant species and subspecies: * Common minke whale (''Balaenoptera acutorostrata'') ** North Atlantic minke whale (''Balaenoptera acutorostrata acutorostrata'') ** North Pacific minke whale (''Balaenoptera acutorostrata scammoni'') * Antarctic minke whale (''Balaenoptera bonaerensis'') * Sei whale (''Balaenoptera borealis'') ** Northern sei whale (''Balaenoptera borealis borealis'') ** Southern sei whale (''Balaenoptera borealis schlegelii'') * Bryde's whale (''Balaenoptera edeni' ...

Fin Whale
The fin whale (''Balaenoptera physalus''), also known as finback whale or common rorqual and formerly known as herring whale or razorback whale, is a cetacean belonging to the parvorder of baleen whales. It is the second-longest species of cetacean on Earth after the blue whale. The largest reportedly grow to long with a maximum confirmed length of , a maximum recorded weight of nearly , and a maximum estimated weight of around . American naturalist Roy Chapman Andrews called the fin whale "the greyhound of the sea ... for its beautiful, slender body is built like a racing yacht and the animal can surpass the speed of the fastest ocean steamship." The fin whale's body is long and slender, coloured brownish-grey with a paler underside. At least two recognized subspecies exist, in the North Atlantic and the Southern Hemisphere. It is found in all the major oceans, from polar to tropical waters. It is absent only from waters close to the pack ice at the poles and relatively sma ...

Neogene
The Neogene ( ), informally Upper Tertiary or Late Tertiary, is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hörnes (1815–1868). During this period, mammals and birds continued to evolve into modern forms, while other groups of life remained relatively unchanged. The first humans (''Homo habilis'') appeared in Africa near the end of the period. Some continental movements took place, the most significant event being the connection of North and South America at the Isthmus of Panama, late in the Pliocene. This cut off the warm ocean currents from the Pacific to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pygmy Blue Whale
The pygmy blue whale (''Balaenoptera musculus brevicauda'') is a subspecies of the blue whale (''Balaenoptera musculus'') found in the Indian Ocean and the southern Pacific Ocean. Reaching lengths of up to 24 metres (79 ft) it is smaller than the other commonly recognized subspecies, ''B. m. musculus'' and ''B. m. intermedia'', the former reaching 28 m (92 ft) and the latter 30 m (98 ft), hence its common name. The pygmy blue whale is the only one of the three identifiable subspecies to be found regularly in tropical waters. It occurs from the sub-Antarctic zone to the southern Indian Ocean and southwestern Pacific Ocean, breeding in the Indian and South Atlantic oceans, and travelling south to above the Antarctic to feed, although they very rarely cross the Antarctic Convergence. A fourth subspecies, ''B. m. indica'', was identified by Blyth in 1859 in the northern Indian Ocean, but difficulties in identifying distinguishing features for this subs ...

Antarctic Blue Whale
The Antarctic ( or , American English also or ; commonly ) is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau and other list of Antarctic and Subantarctic islands, island territories located on the Antarctic Plate or south of the Antarctic Convergence. The Antarctic region includes the ice shelf, ice shelves, waters, and all the island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately wide varying in latitude seasonally. The region covers some 20 percent of the Southern Hemisphere, of which 5.5 percent (14 million km2) is the surface area of the Antarctica continent itself. All of the land and ice shelf, ice shelves south of 60th parallel south, 60°S latitude are administered under the Antarctic Treaty System. Biogeography, Biogeographically, the Antarctic realm is one of eight biogeographic realms of E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blue Whale
The blue whale (''Balaenoptera musculus'') is a marine mammal and a baleen whale. Reaching a maximum confirmed length of and weighing up to , it is the largest animal known to have ever existed. The blue whale's long and slender body can be of various shades of greyish-blue dorsally and somewhat lighter underneath. Four subspecies are recognized: ''B. m. musculus'' in the North Atlantic and North Pacific, ''B. m. intermedia'' in the Southern Ocean, ''B. m. brevicauda'' (the pygmy blue whale) in the Indian Ocean and South Pacific Ocean, ''B. m. indica'' in the Northern Indian Ocean. There is also a population in the waters off Chile that may constitute a fifth subspecies. In general, blue whale populations migrate between their summer feeding areas near the poles and their winter breeding grounds near the tropics. There is also evidence of year-round residencies, and partial or age/sex-based migration. Blue whales are filter feeders; their diet consists almost exclusivel ...

Eden's Whale
Bryde's whale ( Brooder's), or the Bryde's whale complex, putatively comprises three species of rorqual and maybe four. The "complex" means the number and classification remains unclear because of a lack of definitive information and research. The common Bryde's whale (''Balaenoptera brydei'', Olsen, 1913) is a larger form that occurs worldwide in warm temperate and tropical waters, and the Sittang or Eden's whale (''Balaenoptera edeni'', Anderson, 1879) is a smaller form that may be restricted to the Indo-Pacific. Also, a smaller, coastal form of ''B. brydei'' is found off southern Africa, and perhaps another form in the Indo-Pacific differs in skull morphology, tentatively referred to as the Indo-Pacific Bryde's whale. The recently described Omura's whale (''B. omurai'', Wada et al. 2003), was formerly thought to be a pygmy form of Bryde's, but is now recognized as a distinct species. Rice's whale (''B. ricei''), which makes its home solely in the Gulf of Mexico, was once cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Southern Sei Whale
The sei whale ( , ; ''Balaenoptera borealis'') is a baleen whale, the third-largest rorqual after the blue whale and the fin whale. It inhabits most oceans and adjoining seas, and prefers deep offshore waters. It avoids polar and tropical waters and semi-enclosed bodies of water. The sei whale migrates annually from cool, subpolar waters in summer to temperate, subtropical waters in winter with a lifespan of 70 years. Reaching in length and weighing as much as , the sei whale consumes an average of of food every day; its diet consists primarily of copepods, krill, and other zooplankton. It is among the fastest of all cetaceans, and can reach speeds of up to (27 knots) over short distances. The whale's name comes from the Norwegian word for pollock, a fish that appears off the coast of Norway at the same time of the year as the sei whale. Following large-scale commercial whaling during the late 19th and 20th centuries, when over 255,000 whales were killed, the s ...
