Scombridae
The mackerel, tuna, and bonito family, Scombridae, includes many of the most important and familiar food fishes. The family consists of 51 species in 15 genera and two subfamilies. All species are in the subfamily Scombrinae, except the butterfly kingfish, which is the sole member of subfamily Gasterochismatinae. Scombrids have two dorsal fins and a series of finlets behind the rear dorsal fin and anal fin. The caudal fin is strongly divided and rigid, with a slender, ridged base. The first (spiny) dorsal fin and the pelvic fins are normally retracted into body grooves. Species lengths vary from the of the island mackerel to the recorded for the immense Atlantic bluefin tuna. Scombrids are generally predators of the open ocean, and are found worldwide in tropical and temperate waters. They are capable of considerable speed, due to a highly streamlined body and retractable fins. Some members of the family, in particular the tunas, are notable for being partially en ...

Gasterochismatinae
The butterfly kingfish (''Gasterochisma melampus'') is an ocean-dwelling ray-finned bony fish in the mackerel family, Scombridae – a family which it shares with the tunas, mackerels, Spanish mackerels, and bonitos. It, however, represents a lineage distinct from all other scombrids and has therefore been placed in its own genus ''Gasterochisma'' and subfamily Gasterochismatinae. Although taxonomists and the Food and Agriculture Organization of the United Nations have accepted the name "butterfly kingfish", this fish has had many common names, including big-scaled mackerel, bigscale mackerel, butterfly mackerel, butterfly tuna, scaled tunny, scaly tuna, and others. In 1993, the U.S. Food and Drug Administration gave approval for this fish to be marketed simply as "mackerel". Description The juveniles of the butterfly kingfish are characterized by enormous pelvic fins that are longer than the length of its head, and that become more proportional as the fish grows. At any size, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellowfin Tuna
The yellowfin tuna (''Thunnus albacares'') is a species of tuna found in pelagic waters of tropical and subtropical oceans worldwide. Yellowfin is often marketed as ahi, from the Hawaiian , a name also used there for the closely related bigeye tuna (''Thunnus obesus''). The species name, ''albacares'' ("white meat") can also lead to confusion: in English, the albacore (''Thunnus alalunga'') is a different species, while yellowfin is officially designated ''albacore'' in French and referred to as ''albacora'' by Portuguese fishermen. Description The yellowfin tuna is among the larger tuna species, reaching weights over , but is significantly smaller than the Atlantic and Pacific bluefin tunas, which can reach over , and slightly smaller than the bigeye tuna and the southern bluefin tuna. The second dorsal fin and the anal fin, as well as the finlets between those fins and the tail, are bright yellow, giving this fish its common name. The second dorsal and anal fins can be ...

Endothermy
An endotherm (from Greek ἔνδον ''endon'' "within" and θέρμη ''thermē'' "heat") is an organism that maintains its body at a metabolically favorable temperature, largely by the use of heat released by its internal bodily functions instead of relying almost purely on ambient heat. Such internally generated heat is mainly an incidental product of the animal's routine metabolism, but under conditions of excessive cold or low activity an endotherm might apply special mechanisms adapted specifically to heat production. Examples include special-function muscular exertion such as shivering, and uncoupled oxidative metabolism, such as within brown adipose tissue. Only birds and mammals are considered truly endothermic groups of animals. However, Argentine black and white tegu, leatherback sea turtles, lamnid sharks, tuna and billfishes, cicadas, and winter moths are mesothermic. Unlike mammals and birds, some reptiles, particularly some species of python and tegu, possess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scomberomorini
Scomberomorini is a tribe of ray-finned, saltwater, bony fishes that is commonly known as Spanish mackerels, seerfishes, or seer fish. This tribe is a subset of the mackerel family (Scombridae), which it shares with four sister tribes, the tunas, mackerels, bonitos, and butterfly kingfish. Scomberomorini comprises 21 species across three genera. They are pelagic fish, fast swimmers and predatory in nature, that fight vigorously when caught. They are mainly caught using hooks and lines. Taxonomy The following cladogram shows the most likely evolutionary relationships between the Spanish mackerels and the tunas, mackerels, bonitos, and butterfly kingfish. This tribe comprises 21 species in three genera: * '' Acanthocybium'' (Gill, 1862) ** '' A. solandri'' ( Cuvier, 1832), wahoo * '' Grammatorcynus'' (Gill, 1862) ** '' G. bicarinatus'' ( Quoy & Gaimard, 1825), shark mackerel ** '' G. bilineatus'' ( Rüppell, 1836), double-lined mackerel * '' Scomberomorus'' ( Lac ...

Scomber
''Scomber'' is a genus of ray-finned fish in the family Scombridae living in the open ocean found in Atlantic, Indian and Pacific Ocean. The genus ''Scomber'' and the genus ''Rastrelliger'' comprise the tribe Scombrini, known as the "true mackerels". These fishes have an elongated body, highly streamlined, muscular and agile. The eyes are large, the head is elongated, with a big mouth provided with teeth. They have two triangular dorsal fins, with some stabilizing fins along the caudal peduncle. The basic color is blue-green with a silvery white belly and a darker back, usually black mottled. Species There are currently 5 recognized species in this genus: * ''Scomber australasicus'' G. Cuvier, 1832 (Blue mackerel) * '' Scomber colias'' J. F. Gmelin, 1789 (Atlantic chub mackerel) * ''Scomber indicus'' E. M.

Rastrelliger
''Rastrelliger'' is a mackerel genus in the family Scombridae. The three species of ''Rastrelliger'' together with the four species of ''Scomber'' comprise the tribe (biology), tribe Scombrini, known as the "true mackerels".

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxa ranked above species are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoological Society Of London
The Zoological Society of London (ZSL) is a charity and organization devoted to the worldwide animal conservation, conservation of animals and their habitat conservation, habitats. It was founded in 1826. Since 1828, it has maintained London Zoo, and since 1931 Whipsnade Zoo. History On 29 November 1822, the birthday of John Ray, "the father of modern zoology", a meeting held in the Linnean Society in Soho Square led by Rev. William Kirby (entomologist), William Kirby, resolved to form a "Zoological Club of the Linnean Society of London". Between 1816 and 1826, discussions between Stamford Raffles, Humphry Davy, Joseph Banks and others led to the idea that London should have an establishment similar to the Jardin des Plantes in Paris. It would house a zoological collection "which should interest and amuse the public." The society was founded in April 1826 by Stamford Raffles, Sir Stamford Raffles, the Henry Petty-Fitzmaurice, 3rd Marquess of Lansdowne, Marquess of Lansdo ...
