Malthopsis gnoma Bradbury, 1998 | |
Malthopsis gnoma, the Atlantic triangular batfish, gnome seabat or grotesque seabat, is a species of marine ray-finned fish belonging to the family Ogcocephalidae, the deep-sea batfishes. The grotesque seabat is found in the Western Atlantic Ocean, in the Gulf of Mexico and Caribbean.
Malthopsis gnoma was first formally described in 1998 by the American ichthyologist Margaret G. Bradbury with its type locality given as off the northern coast of Cuba at 22°44'N, 78°41'W from a depth between 274 and 329 m (899 and 1,079 ft). [2] This species is a member of the genus Malthopsis , the most basal genus in the "Indo-Pacific" clade in the family Ogcocephalidae. [3] The family Ogcocephalidae is classified in the monotypic suborder Ogcocephaloidei within the order Lophiiformes, the anglerfishes in the 5th edition of Fishes of the World . [4]
Malthopsis gnoma has the genus name Malthopsis which suffixes opsis, meaning "resembles", onto Malthe, a synonym of Ogcocephalus , although this genus has two gills on either side. The specific name, gnoma, means "gnome-like", an allusion to its small size and rather grotesque appearance. [5]
Mathopsis gnoma has a flattened head which is higher than the rest of the body disc, which is triangular in shape. It has a long tail. The mouth is small and the illicial cavity is also small. The esca is a bulb with no other lobes. Overhanging the mouth is the small, obviously upturned, cone-shaped rostrum. The eyes are not protected by a transparent cover. The scales at the angle of the operculum resemble bucklers and have a well-developed backwards directed spine at their ends. The small gill opening are situated to the rear of the upper base of the pectoral fin, which are clearly separate from the body. The small dorsal and anal fins are located towards the rear of the body disc, the pelvic fins are not reduced. The scales on the body take the form of bucklers and spines with the lower body being densely covered in scales and the lower side of the tail being desnely covered in spines apart from 2 scale rows of large conical scales. [6] The small mouth is terminal and has simple teeth on the jaws, tongue, palate and vomer. [7] The dorsal fin is supported by 4 or 5 soft rays. This species has a maximum published standard length of 6.1 cm (2.4 in). [8] There are dark reticulated lines on the body and tail with a dark stripe through the middle of the dorsal fin. [6]
Malthopsis gnoma found in the western Atlantic Ocean where its has been recorded from the Bahamas, the Campeche Bank to northwestern Cuba in the southern Gulf of Mexico, in the Caribbean Sea from Cuba through both the Greater and Lesser Antilles as far as Barbados. It also occurs along the eastern coast of Central Americafrom Quintana Roo, Mexico to Curaçao. This is a bathydemersal fish which is found on the upper continental slope on soft substrates at depths between 91 and 475 m (299 and 1,558 ft), typically 275 to 475 m (902 to 1,558 ft). [1]
Malthopsis gnoma is a carnivorous species feeding on crustaceans, molluscs and worms. The eggs and larvae are pelagic. [6]
The pancake batfish, Atlantic pancake batfish, Louisiana pancake batfish or spiny batfish, is a species of marine ray-finned fish belonging to the family Ogcocephalidae, the deep sea batfishes or seabats. This species is found in the Western Atlantic Ocean.
Ogcocephalidae is a family of anglerfish specifically adapted for a benthic lifestyle of crawling about on the seafloor. Ogcocephalid anglerfish are sometimes referred to as batfishes, deep-sea batfishes, handfishes, and seabats. They are found in tropical and subtropical oceans worldwide. They are mostly found at depths between 200 and 3,000 m, but have been recorded as deep as 4,000 m (13,000 ft). A few species live in much shallower coastal waters and, exceptionally, may enter river estuaries.
The starry handfish, starry seabat or minipizza batfish, is species of marine ray-finned fish belonging to the family Ogcocephalidae, the deep-sea batfishes or seabats. This fish is found on the continental shelves of the Indo-Pacific oceans at depths of between 50 and 400 m. They are up to 30 cm long.
Ogcocephalus parvus, the roughback batfish, is a species of marine ray-finned fish belonging to the family Ogcocephalidae, the batifishes. This species has a wide distribution in the Western Atlantic Ocean.
Halieutichthys is a genus of marine ray-finned fishes belonging to the family Ogcocephalidae, the deep-sea batfishes or sea bats. The fishes in this genus are found in the western Atlantic Ocean.
Malthopsis, the gnome batfishes or triangular batfishes, is a genus of marine ray-finned fishes belonging to the family Ogcocephalidae, the deep sea batfishes. The triangular batfishes are distributed throughout the warmer waters of the world, although they are absent from the Eastern Atlantic Ocean. The genus was originally proposed in 1891 by the British naturalist Alfred W. Alcock.
Dibranchus is a genus of marine ray-finned fishes belonging to the family Ogcocephalidae, the deep sea batfishes. The fishes in this genus are widely distributed in the Atlantic, Indian and Pacific Oceans.
Ogcocephalus is a genus of marine ray-finned fishes belonging to the family Ogcocephalidae, the deep sea batfishes. The species in this genus are found in the Eastern Pacific Ocean and Western Atlantic Ocean, with most species in the eastern Atlantic Ocean where they live at shallower depths than the other ogcocephalid genera.
Ogcocephalus corniger, the longnose batfish, is a species of ray-finned fish belonging to the family Ogcocephalidae, the deep sea batfishes. This fish is found at depths between 29 and 230 m in the Atlantic Ocean, ranging from North Carolina to the Gulf of Mexico and the Bahamas. Like other members of the family Ogcocephalidae, it has a flat triangular body with coloring varying from yellowish to purple with pale, round spots. The lips are orange-red. Projecting from its head is a characteristic structure that is shared by other anglerfish.
Halieutichthys bispinosus, the two-spine batfish or spiny batfish, is a species of marine ray-finned fish belonging to the family Ogcocephalidae, the deep sea batfishes or seabats. This species is found in the Western Atlantic Ocean.

Ogcocephalus porrectus, the rosy-lipped batfish, is endemic to Cocos Island off the Pacific coast of Costa Rica. Though members of Ogcocephalidae occur in tropical, warm waters in both the Western Atlantic and Eastern Pacific. Rosy-lipped batfish generally reside in shallow to deep water benthic zones with a bathymetric range of 35 – 150 m. The syntypic series was collected at 120 m on a rocky bottom. What makes this fish distinctive are its rosy red lips, specialized pectoral fins used for "walking", and an illicium used for attracting prey.
