Mackerel is a common name applied to a number of different species of pelagic fish, mostly from the family Scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment.
Herring are forage fish, mostly belonging to the family Clupeidae.
"Sardine" and "pilchard" are common names that refer to various small, oily forage fish in the herring family Clupeidae. The term "sardine" was first used in English during the early 15th century and may come from the Mediterranean island of Sardinia, around which sardines were once abundant.
Carcharhiniformes, the ground sharks, with over 270 species, are the largest order of sharks. They include a number of common types, such as catsharks, swellsharks, and the sandbar shark.
The roosterfish, Nematistius pectoralis, is a game fish found in the warmer waters of the East Pacific from Baja California to Peru. It is the only species in the genus Nematistius and the family Nematistiidae. It is distinguished by its "rooster comb", seven very long spines of the dorsal fin.
Snipe eels are a family, Nemichthyidae, of eels that consists of nine species in three genera. They are pelagic fishes, found in every ocean, mostly at depths of 300–600 m but sometimes as deep as 4000 m. Depending on the species, adults may reach 1–2 m (39–79 in) in length, yet they weigh only 80-400 g. They are distinguished by their very slender jaws that separate toward the tips as the upper jaw curves upward. The jaws appear similar to the beak of the bird called the snipe. Snipe eels are oviparous, and the juveniles, called Leptocephali, do not resemble the adults but have oval, leaf-shaped and transparent bodies. Different species of snipe eel have different shapes, sizes and colors. The similarly named bobtail snipe eel is actually in a different family and represented by two species, the black Cyema atrum and the bright red Neocyema erythrosoma.
Percina austroperca, the southern logperch, is a small species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. They are highly resilient with a minimum population doubling time of less than 15 months. It is found in the Escambia and Choctawhatchee river systems in western Florida and southern Alabama.
Trematochromis benthicola is a ray-finned fish species in the cichlid family (Cichlidae), subfamily Pseudocrenilabrinae and the tribe Haplochromini. It is found throughout Lake Tanganyika in the Burundian, the Democratic Republic of the Congo, Tanzanian, and Zambian shoreline. Its preferred habitat are the hidden recesses of caves in shallow water.
Ctenochromis horei is a species of haplochromine cichlid which is found in East Africa.
Ctenochromis pectoralis, the Pangani haplo, is a species of fish in the family Cichlidae. It was originally characterized in the Pangani River of Tanzania, and may also be present in Kenya. It is listed as extinct by IUCN as a result of a 1996 evaluation, but this appears to be incorrect. A more recent IUCN publication stated that this species is not endangered in any way.
Fish are very diverse animals and can be categorised in many ways. This article is an overview of some of ways in which fish are categorised. Although most fish species have probably been discovered and described, about 250 new ones are still discovered every year. According to FishBase, 34,300 species of fish had been described as of September 2020. That is more than the combined total of all other vertebrate species: mammals, amphibians, reptiles and birds.
Several species of fish are claimed to produce hallucinogenic effects when consumed. For example, Sarpa salpa, a species of sea bream, is commonly claimed to be hallucinogenic. These widely distributed coastal fish are normally found in the Mediterranean and around Spain, and along the west and south coasts of Africa. Occasionally they are found in British waters. They may induce hallucinogenic effects similar to LSD if eaten. However, based on the reports of exposure they are more likely to resemble hallucinogenic effects of deliriants than the effects of serotonergic psychedelics such as LSD. In 2006, two men who apparently ate the fish experienced hallucinations lasting for several days. The likelihood of hallucinations depends on the season. Sarpa salpa is known as "the fish that makes dreams" in Arabic.
Labroides is a genus of wrasses native to the Indian and Pacific Oceans. This genus is collectively known as cleaner wrasses, and its species are cleaner fish.
Heckel’s Orontes barbel or Levantine barbel is a species of ray-finned fish in the genus Luciobarbus from the Orontes River basin in the Near East.
Ophiclinus pectoralis, the whiteblotch snakeblenny, is a species of clinid found in reefs around western Australia preferring weedy and sandy areas at depths of about 13 metres (43 ft). It can reach a maximum length of 6 centimetres (2.4 in) TL.
Dactyloscopus pectoralis, the whitesaddle stargazer, is a species of sand stargazer native to the Pacific coast of Baja California, Mexico and the Gulf of Mexico. It can reach a maximum length of 5.2 centimetres (2.0 in) TL.
Bathyonus is a genus of cusk-eels.
The Sawspine catfish, alternatively referred to as the Sawspined catfish, is a species of catfish in the family Ariidae. It was described by Patricia J. Kailola in 2000, originally under the genus Arius. It inhabits marine and brackish waters in Australia, Irian Jaya, and possibly also Papua New Guinea. It reaches a maximum fork length of 39.3 cm (15.5 in).
