Gigantactis elsmani | |
Gigantactis elsmani, Elsman's whipnose, is a species of marine ray-finned fish belonging to the family Gigantactinidae, the whipnose anglers. This species is found in the deeper waters of the Atlantic and Pacific Oceans.
Gigantactis elsmani was first formally described in 1981 by Erik Bertelsen, Theodore W. Pietsch and Robert J. Lavenberg with its type locality given as the South Atlantic at 10°57'S, 11°20'W, Walther Herwig station 459/71, from a depth of 0–1,900 m (0–6,234 ft). [2] This species is placed within the genus Gigantactis which the 5th edition of Fishes of the World classifies within the family Gigantactinidae, a family within the suborder Ceratioidei, the deep sea anglerfishes of the order Lophiiformes, the anglerfishes. [3]
Gigantactis elsmani is a member of the genus Giganactis, the name of which is a combination of gigantos, meaning "giant", with actis, which means "ray", an allusion to the unusually long illicium of the genus's type species, G. vanhoeffeni . The specific name honours Kai L. Elsman, who illustrated the review of the whipnose anglers the species was first described in. [4]
Gigantactis elsmani has relatively large metamorphosed females, which are black and have a comparatively short illicium, which has a length equivalent to 93-126% of the fish's standard length. It does not have an elongated bulb on the esca, which has a single filamentous appendage on its base and two near its tip. There are no papillae on the bulb of the esca. There is no cluster of white filaments at the base of the illicium. There are 5 soft rays in the dorsal fin and 4 or 5 in the anal fin. The teeth on the dentary are comparatively short and arranged in 5 or 6 rows. [5] This species has a maximum published standard length of 43.5 cm (17.1 in). [6]
Giganticis elsmani has been recorded in the southern Atlantic and Pacific oceans, where it has been reported to occur from the surface down to depths of 3,000 m (9,800 ft). [1]
Certaiidae, the warty sea devils, caruncled seadevils or seadevils, are a family of marine ray-finned fishes belonging to the suborder Ceratioidei, the deep-sea anglerfishes, in the anglerfish order Lophiiformes. The warty sea devils are sexually dimorphic with the small males being obligate sexual parasites of the much larger females. The fishes in this family are widely distributed from polar to tropical seas around the world.
Fanfins or hairy anglerfish are a family, Caulophrynidae, of marine ray-finned fishes within the order Lophiiformes, the anglerfishes. The fishes in this family are found almost around the world in the deeper, aphotic waters of the oceans.
Oneirodidae, the dreamers are a family of marine ray-finned fishes belonging to the order Lophiiformes, the anglerfishes. These fishes are deepwater fishes found in the Atlantic, Indian and Pacific Oceans and it is the most diverse family of fishes in the bathypelagic zone.
Thaumatichthyidae, the wolftrap anglers, is a small family of marine ray-finned fishes, also called the wolftrap seadevils, classified within the suborder Ceratioidei, the deep-sea anglerfishes. They have distinctive upper jaws with movable premaxillaries that can be lowered to form a cage-like trap around the much shorter lower jaw.
Gigantactis is a genus of marine ray-finned fish belonging to the family Gigantactinidae, the whipnose anglers. The fishes in this genus have a circumglobal distribution in the deep waters of the tropical and temperate zones of the Atlantic, Indian and Pacific Oceans.
The whipnose anglers are a family, the Gigantactinidae, of marine ray-finned fishes which is classified within the suborder Ceratioidei, the deep sea anglerfishes. These fishes are found in the Atlantic, Indian and Pacific Oceans.
Bufoceratias wedli is a species of deep sea marine ray-finned fish belonging to the family Diceratiidae, the double anglers. This anglerfish is found in deep water over the continental shelf in the tropical and subtropical areas of the Eastern and Western Atlantic Oceans. It is the type species of the genus Bufoceratias and like other members of that genus is known only from adult females, the unknown males are thought to be free living rather than sexual parasites of the females like those of some other deep sea anglerfishes.
Himantolophus groenlandicus, the Atlantic footballfish or Atlantic football-fish, is a species of marine ray-finned fish belonging to the family Himantolophidae, the footballfishes. This fish is found primarily in mesopelagic depths of the ocean. Despite its name, this species might not be restricted to the Atlantic Ocean, with its range possibly extending into the Indian Ocean and to the Pacific Ocean. It is found in tropical and temperate regions.
Caulophryne polynema is a species of marine ray-finned fish belonging to the family Caulophrynidae, the fanfins. This species is a deepwater species which is found in the Atlantic and Pacific Oceans. Like other deepwater anglerfishes it shows extreme sexual dimorphism with the males being much smaller than the females and acting as sexual parasites of the females.
Ceratias is a genus of marine ray-finned fish belonging to the family Ceratiidae, the warty sea devils. This fishes in this genus are found throughpuit the world's oceans.
Chirophryne is a monospecific genus of marine ray-finned fish belonging to the family Oneirodidae, the dreamers, a family of deep sea anglerfishes. The only species in the gneus is Chirophryne xenolophus, the longhand dreamer. This species is known from a few locations in the Atlantic and Pacific Oceans.
Dolopichthys is a genus of marine ray-finned fish belonging to the family Oneirodidae, the dreamers, a family of deep sea anglerfishes. These predatory, deep-sea fishes are found in the tropical and subtropical oceans around the world.
Microlophichthys is a genus of marine ray-finned fish belonging to the family Oneirodidae, the dreamers, a family of deep sea anglerfishes. The species in this genus are found in the tropical and subtropical parts of the Atlantic, Indian and Pacific Oceans.
Caulophryne pelagica is a species of marine ray-finned fish belonging to the family Caulophrynidae, the fanfins. This species is a deepwater species which is found in the eastern Atlantic, Indian Ocean, Pacific Ocean and Southern Ocean. Its biology is little known but similar species show extreme sexual dimorphism with the very small makes seeking out and attaching themselves to the much larger females and becoming parasites of the females.
Ceratias tentaculatus, the southern seadevil, is a species of marine ray-finned fish belonging to the family Ceratiidae, the warty seadevils. This is bathydemersal species which can be found at depths ranging from 100 to 2,900 metres. It is restricted to the Southern Hemisphere.
Ceratias uranoscopus, the stargazing seadevil, is a species of marine ray-finned fish belonging to the family Ceratiidae, the warty sea devils. The fish is both bathypelagic and mesopelagic and can typically be found at depths ranging from 500 to 1,000 metres. It is endemic to tropical waters and can be found in the Atlantic, Pacific, and Indian Oceans.
