Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilot Fish
The pilot fish (''Naucrates ductor'') is a carnivorous fish of the trevally, or jackfish family, Carangidae. It is widely distributed and lives in warm or tropical open seas. Description The pilot fish congregates around sharks, rays, and sea turtles, where it eats ectoparasites on, and leftovers around the host species; younger pilot fish are usually associated with jellyfish and drifting seaweeds. They are also known to follow ships, sometimes for long distances; one was found in County Cork, Ireland, and many pilot fish have been sighted on the shores of England. Their fondness for ships led the ancients to believe that they would navigate a ship to its desired course. The pilot fish's color is between dark blue and blackish-silver, with the belly being lighter in color.Eschmeyer & Herald 1999, p. 208. The pilot fish is also known to have a temporary variation of color when excited; its dark-colored bars disappear, and its body turns silvery-white, with three broad blue patc ...

Yellowtail Horse Mackerel
The yellowtail horse mackerel (''Trachurus novaezelandiae''), also known as the yellowtail scad, is a jack in the family Carangidae found around Australia and New Zealand at depths to 500 m. Its length is up to . The yellowtail scad is the only member of the monotypic genus ''Atule'' and is distinguished from similar species by a well-developed adipose eyelid and finlet-like extensions of the last rays of the dorsal and anal fins. It inhabits coastal areas such as bays and coral reefs, preying on small fishes and crustaceans. The yellowtail scad is an important component of fisheries throughout its range, taken by a number of netting and hook-and-line methods. It is a prized food fish in some regions and is cooked or preserved by a variety of methods. Description The body profile of the yellowtail horse mackerel is a moderately compressed, oval shape body. The yellowtail horse mackerel is very similar to the greenback horse mackerel, but has 68 to 73 lateral line scutes, compared ...

Japanese Horse Mackerel
The Japanese jack mackerel (''Trachurus japonicus''), also known as the Japanese horse mackerel or Japanese scad, is a species named after its resemblance to mackerel but which is in the family Carangidae, the jacks, pompanos, trevallies and scads. Their maximum reported length is with a common length of . They have a maximum reported weight of and a maximum reported age of 12 years. They are found around the coast of Japan, apart from Okinawa Island, usually on sandy bottoms of deep. They feed mainly on small crustaceans such as copepods, and shrimps and small fish. They are similar to the yellowtail horse mackerel around New Zealand and Australia, apart from having more gill rakers and larger eyes. The Japanese name for the horse mackerel is ''aji'' (あじ), and by default generally implies the species ''Trachurus japonicus'' (which can be more specifically referred to as ''ma-aji'' (まあじ), literally "true ''aji''"). The name is most commonly written in hiragana; alth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenback Horse Mackerel
The greenback horse mackerel or greenback scad (''Trachurus declivis'') is a species of jack in the family Carangidae, found around western and southern Australia, and around New Zealand, from the surface to depths of 460 m. Its length is up to 64 cm. Its common name derives from the legend that other smaller species of fish could ride on its back over great distances. It is an important commercial fish and sports fishing quarry although it has strong tasting flesh.

Bigeye
The Priacanthidae, the bigeyes, are a family of 18 species of marine ray-finned fishes. " Catalufa" is an alternate common name for some members of the Priacanthidae. The etymology of the scientific name (, to bite + , thorn) refers to the family's very rough, spined scales. The common name of "bigeye" refers to the member species' unusually large eyes, suited to their carnivorous and nocturnal lifestyles. Priacanthidae are typically colored bright red, but some have patterns in silver, dusky brown, or black. Most species reach a maximum total length of about , although in a few species lengths of over are known. Most members of this family are native to tropical and subtropical parts of the Indian and Pacific Oceans, but four species (''Cookeolus japonicus'', ''Heteropriacanthus cruentatus'', ''Priacanthus arenatus'', and ''Pristigenys alta'') are found in the Atlantic. They tend to live near rock outcroppings or reefs, although a few are known to inhabit open waters. Many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saurel
Jack mackerels or saurels are marine fish in the genus ''Trachurus'' of the family Carangidae. The name of the genus derives from the Greek words ''trachys'' ("rough") and ''oura'' ("tail"). Some species, such as ''T. murphyi'', are harvested in purse seine nets, and overfishing (harvesting beyond sustainable levels) has sometimes occurred. It is often used in Japanese cuisine, where it is called ''aji'', in Turkish cuisine, where it is called ''istavrit'', and in Portuguese Cuisine, where it is called ''carapau''.

Torpedo Scad
The torpedo scad (''Megalaspis cordyla''), also known as the hardtail scad, finny scad, finletted mackerel scad or cordyla scad, is a species of moderately large marine fish classified in the jack and horse mackerel family, Carangidae. The torpedo scad is distributed throughout the tropical Indo-Pacific region, ranging from South Africa in the west to Tonga in the east, extending to Japan in the north and Australia in south. It is a schooling pelagic fish which occupies the surface layers of both inshore and offshore oceanic waters. The torpedo scad is easily identified by both its 'torpedo' shaped body and a series of detached finlets at the rear of both the dorsal and anal fins. The largest recorded individual was 80 cm long and weighed 4 kg, although it is more common at lengths less than 40 cm. It is a predatory species, taking a variety of fish, cephalopods and crustaceans by both active and filter feeding. There is a shift in diet as the species grow; howeve ...

Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Crevalle Jack
The crevalle jack (''Caranx hippos''), also known as the common jack, black-tailed trevally, couvalli jack, black cavalli, jack crevale, or yellow cavalli is a common species of large marine fish classified within the jack family, Carangidae. The crevalle jack is distributed across the tropical and temperate waters of the Atlantic Ocean, ranging from Nova Scotia, Canada to Uruguay in the western Atlantic and Portugal to Angola in the eastern Atlantic, including the Mediterranean Sea. It is distinguishable from similar species by its deep body, fin colouration and a host of more detailed anatomical features, including fin ray and lateral line scale counts. It is one of the largest fish in the genus ''Caranx'', growing to a maximum known length of 124 cm and a weight of 32 kg, although is rare at lengths greater than 60 cm. The crevalle jack inhabits both inshore and offshore waters to depths of around 350 m, predominantly over reefs, bays, lagoons and occasionally estuar ...
