WArgyripnus is an oceanic ray-finned fish genus which belongs in the family Sternoptychidae. They are commonly known as bristle-mouth fishes, but that may also refer to the related bristlemouth family (Gonostomatidae). A. iridescens is called "pearlside", which usually refers to the closely related genus Maurolicus.
WArgyropelecus is an oceanic ray-finned fish genus in the deep sea hatchetfish family Sternoptychidae. A collective name is "silver hatchetfishes", but this can also refer to a species of the freshwater hatchetfishes which are not particularly closely related to. The large pupils of these marine hatchetfishes enable them to see dim objects in the deep sea, where light barely penetrates.
WThe lovely hatchetfish or Atlantic silver hatchetfish is a species of fish in the family Sternoptychidae. It may exceed 70 millimetres (2.8 in) standard length (SL). It lives in the mesopelagic zone of all oceans and performs diel vertical migration. A. aculeatus feeds on a large range of prey items; in the Gulf of Mexico ostracods and copepods dominated the diet of small individuals and euphausiids, molluscs, and fish the diet of larger ones. The silvery coloration and bioluminescence of the lovely hatchetfish allows it to hide from predators and prey in the down-welling light of the twilight zone.
WArgyropelecus hemigymnus, the half-naked hatchetfish, short silver hatchetfish or spurred hatchetfish, is a deep-sea hatchetfish of the genus Argyropelecus found mesopelagically in the Atlantic, Indian, and Pacific Oceans as well as in the Mediterranean Sea. It is a small species rarely exceeding 38 millimetres (1.5 in) standard length. It feeds on zooplankton, particularly ostracods and copepods. Sexual maturation occurs at length of about 22 mm, and adult males have more developed olfactory organs than females, i.e. the species is sexually dimorphic.
WBathophilus is a genus of barbeled dragonfishes native to the ocean depths of the Pacific, Atlantic and Indian oceans.
WBonapartia pedaliota, the longray fangjaw, is a species of bristlemouth found in the Atlantic and Indian Oceans. It is the only described species in its genus. This species grows to a length of 7.2 centimetres (2.8 in) SL.
WChauliodus danae, or dana viperfish, is a species of viperfish in the family Stomiidae. The Dana Viperfish is mostly found in the bathyal zone. The species was first caught and recognised on the Dana expeditions 1920-1922 and named after the research vessel Dana.
WCyclothone is a genus containing 13 extant species of bioluminescent fish, commonly known as 'bristlemouths' or 'bristlefishes' due to their shared characteristic of sharp, bristle-like teeth. These fishes typically grow to around 1-3 inches. They are most commonly found in the mesopelagic zone of the ocean, and are mostly found at depths of over 300 meters.
WGonostoma is a genus of bristlemouths.
WThe giant hatchetfish or greater silver hatchetfish, is a marine fish of the genus Argyropelecus. It is found in every ocean except the north Pacific in the mesopelagic zone of tropical and subtropical waters. "Giant" in relative terms only, this is the largest species of marine hatchetfishes, often exceeding 110 millimetres (4.3 in) standard length.
WIchthyococcus are a genus of lightfishes. It is one of seven genera in the family Phosichthyidae.
WIchthyococcus ovatus is a lightfish of the genus Ichthyococcus.
WIdrissia is a primitive genus of the order Stomiiformes, and is an extinct relative of marine hatchetfish and viperfish. Idrissia's position in the order is in doubt, however, as scientists have not studied enough fossil specimens to determine exactly which stomiiforms the genus is most closely related to.
WMalacosteus niger is a species of fish in the family Stomiidae, the barbeled dragonfishes. It is known by the common names northern stoplight loosejaw, lightless loosejaw, black loosejaw, and black hinged-head. It lives in oceans around the world from tropical to subarctic waters.
WMargrethia is a genus of bristlemouths.
WMargrethia obtusirostra, the Bighead portholefish, is a bristlemouth of the family Gonostomatidae, found in the tropical and subtropical Indo-Pacific and Atlantic oceans, at depths of between 100 and 600 m. Its length is between 5 and 8 cm.
WMaurolicus is an oceanic ray-finned fish genus which belongs in the marine hatchetfish family Sternoptychidae. They are commonly known as pearlsides, but the brilliant pearlside is the related Argyripnus iridescens. Occasionally, "bristle-mouth fishes" is used as a common name, but that usually refers to the genus Argyripnus or the family Gonostomatidae.
WMueller's pearlside or Mueller's bristle-mouth fish, Maurolicus muelleri, a marine hatchetfish of the genus Maurolicus, is found in deep tropical, subtropical and temperate waters of the Pacific Ocean and the Atlantic Ocean, from the surface to depths of 1,500 metres (4,900 ft). Its can grow up to 8 centimetres (3.1 in) at maximum.
WLightfishes are small stomiiform fishes in the family Phosichthyidae
WPhotostomias is a genus of barbeled dragonfishes.
WPolyipnus is a genus of oceanic ray-finned fish in the family Sternoptychidae. This is the largest genus of the marine hatchetfishes subfamily Sternoptychinae and indeed of the entire Sternoptychidae. It is not quite as apomorphic as their relatives; it may be that the genus is actually a paraphyletic assemblage of less advanced Sternoptychinae and would need to be split.
WPolymetme is a genus of lightfishes.
WSigmops is a genus of bristlemouths.
WSnaggletooths or stareaters are any of a number of small, deep-sea stomiid fish in the genus Astronesthes. They possess a bioluminescent red chin barbel that the fish use as a lure to attract small prey into striking distance.
WThe stareye lightfish is a species in the monotypic genus of Pollichthys. They are small stomiiform fishes found in oceans throughout the world. The maximum length is 6 cm. The genus is named after the Belgian ichthyologist Max Poll who described the species in 1953, originally placing it in the genus Yarrella. The species is named after Günther Maul.
WSternoptyx is an oceanic ray-finned fish genus which belongs in the family Sternoptychidae. This is the type genus of the Sternoptychidae, as well as the marine hatchetfish subfamily Sternoptychinae.
WStomias is a genus of barbeled dragonfishes. They live in the mesopelagic zone of all oceans and show diel vertical migration and sexual dimorphism (males are smaller, have larger eyes and larger postorbital photophores than females.
