Gempylidae
The Gempylidae are a family of scombriform ray-finned fishes commonly known as snake mackerels or escolars. The family includes about 25 species. They are elongated fishes with a similar appearance to barracudas, having a long dorsal fin, usually with one or finlets trailing it. The largest species, including the Thyrsites, snoek (''Thyrsites atun''), grow up to 2 m long, and the oilfish (''Ruvettus pretiosus'') can reach 3 m, though they rarely surpass 150 cm. Like the barracudas, they are predators, with fang-like teeth.

Oilfish
Oilfish (''Ruvettus pretiosus'') are a species of snake mackerel with a cosmopolitan distribution in tropical and temperate oceans. They can be found at depths from , but most often between . Oilfish can grow to a length of , though most do not exceed . It is the only known member of its genus. Description Oilfish are large, fusiform fish which often grow to and a maximum of . Other distinctive features of this fish include the large fangs, rough scales, two pairs of finlets, and a uniformly brown coloration. Oilfish meat is extremely oily, containing high lipid concentrations. Though edible, the oil mainly consists of wax esters, which makes the meat act as a laxative if consumed in large quantities. Habitat and ecology Oilfish are distributed throughout tropical and temperate waters across the world, being recorded in the Atlantic, Indian, and Pacific oceans, including the Mediterranean Sea. They are found in the deep water benthic environments of continental slopes an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thyrsitoides
The blacksail snake mackerel (''Thyrsitoides marleyi''), known also as the black snoek, is a species of snake mackerel found in the Indo-Pacific from shallow water to a depth of at least where they appear to prefer slopes on seamounts and ridges. They are known for making diel vertical migrations to near-surface waters at night, feeding on fish, squid and crustaceans. This species reaches a total length of though most are around . This species is of minor importance to local commercial fisheries. It is at the only member of the genus ''Thyrsitoides'', making the genus monotypic. However, a second extinct species, '' T. zarahoustrae'' Arambourg, 1967, is known from the Late Eocene-aged Pabdeh Formation of Iran and potentially the Early Oligocene of Romania Romania is a country located at the crossroads of Central Europe, Central, Eastern Europe, Eastern and Southeast Europe.

Thyrsites Atun
''Thyrsites atun'' (Bengt Anders Euphrasén, Euphrasén, 1791), known as the snoek in South Africa and as the barracouta in Australasia, is a long, thin species of Gempylidae, snake mackerel found in the seas of the Southern Hemisphere, and a popular food fish in South Africa, particularly along the west and southwest coast. Despite its Australasian name, it is not closely related to the barracuda. Description The fish can reach a length of fish measurement, SL though most do not exceed SL. The maximum recorded weight for this species is . It is very important to commercial fisheries and is also a popular game fish. It is currently the only known member of its genus. ''T. atun'' has 19 to 21 dorsal spines and about 113 dorsal rays, 1 anal spine and 10 to 13 anal rays, 35 vertebrae.

Gempylus Serpens
The snake mackerel (''Gempylus serpens'') is the sole species of fish in the monotypic genus ''Gempylus'', belonging to the family Gempylidae (which is also referred to generally as "snake mackerels"). It is found worldwide in tropical and subtropical oceans between the latitudes of 42°N and 40°S; adults are known to stray into temperate waters. It is found to a depth of . Populations of the snake mackerel from the Atlantic and the Indo-Pacific differ in vertebral count (51–55 versus 48–50) and number of first dorsal fin spines (30–32 versus 26–30), and so may represent separate species. Description The snake mackerel has a very long, slender, laterally compressed body. It has a long, pointed head, measuring 17–18% of the standard length, and a large mouth with the lower jaw protruding beyond the upper. Both jaws are densely packed with sharp teeth; the first few teeth in the upper jaw are enlarged into fangs. The pectoral fins contain 12–15 rays; the pelvic fi ...

Nealotus Tripes
The black snake mackerel (''Nealotus tripes'') is a species of snake mackerel found worldwide in both tropical and temperate waters where they are found at depths of from making diel vertical migrations from mesopelagic depths to the surface at night. It can reach a length of SL though most do not exceed SL. It is important to local peoples as a food fish. This species is currently the only known member of its genus, ''Nealotus''.
