"Sardine" and "pilchard" are common names for 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 Italian island of Sardinia, around which sardines were once abundant.
The Gonostomatidae are a family of mesopelagic marine fish, commonly named bristlemouths, lightfishes, or anglemouths. It is a relatively small family, containing only eight known genera and 32 species. However, bristlemouths make up for their lack of diversity with relative abundance, numbering in the hundreds of trillions to quadrillions. Two genera in the family, Cyclothone and Vinciguerria are thought to be the most abundant vertebrate genera in the world.
Poecilia sphenops is a species of fish, of the genus Poecilia, known under the common name molly; to distinguish it from its congeners, it is sometimes called short-finned molly or common molly. They inhabit fresh water streams and coastal brackish and marine waters from Mexico to Colombia. The wild-type fishes are dull, silvery in color. The molly can produce fertile hybrids with many Poecilia species, most importantly the sailfin molly. The male mollies generally tend to be mildly aggressive.
The garfish, also known as the garpike or sea needle, is a pelagic, oceanodromous needlefish found in brackish and marine waters of the Atlantic Ocean and the Mediterranean, Caribbean, Black, and Baltic Seas.
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.
The Atlantic pomfret, also known as Ray's bream, is a species of marine ray-finned fish, a pomfret of the family Bramidae. It is found in the Atlantic, Indian, and South Pacific Oceans, at depths down to 1,000 m (3,300 ft).
Thunnus is a genus of ocean-dwelling, ray-finned bony fish from the mackerel family, Scombridae. More specifically, Thunnus is one of five genera which make up the tribe Thunnini – a tribe that is collectively known as the tunas. Also called the true tunas or real tunas, Thunnus consists of eight species of tuna, divided into two subgenera. The word Thunnus is the Middle Latin form of the Greek thýnnos – which is in turn derived from thynō. The first written use of the word was by Homer.
An anchovy is a small, common forage fish of the family Engraulidae. Most species are found in marine waters, but several will enter brackish water, and some in South America are restricted to fresh water.
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.
Barilius shacra is a fish in genus Barilius of the family Cyprinidae.
The marlin sucker or spear-fish remora is a species of remora found all over the world in tropical and temperate seas. It can reach up to 40 cm (16 in) in standard length. It normally lives attached to a larger fish; its host preference is for marlins and sailfishes, but it will attach to other large fish.
Ichthyoelephas is a genus of South American freshwater fish from the family Prochilodontidae.
Atherinopsis californiensis, the jack silverside or jacksmelt, is a species of neotropical silverside native to the Pacific coast of North America from Oregon, United States to southern Baja California, Mexico. This species grows to 45 cm (18 in) in total length and is important commercially as a source of human food. It is the only known member of its genus. The adults occur in inshore areas, such as bays. They form schools. This species is a demersal spawners in inshore habitats, it is oviparous and the larvae are planktonic, living at the very surface of the water and feeding on phytoplankton. The eggs are attached to one another and to the substrate by adhesive filaments in the chorion.
Priapichthys is a genus of poeciliid fishes native to Costa Rica, Panama and Colombia.
the African leaffish is a species of African leaffish native to fresh waters of western Africa. Although placed in the family Nandidae by FishBase and by the 5th Edition of Fishes of the World many recent authorities place Polycentropsis in Polycentridae.
