The Atlantic batfish (Dibranchus atlanticus) [3] is a species of marine ray-finned fish belonging to the family Ogcocephalidae, the deep-sea batfishes. It is found in deep water in the Atlantic Ocean where it lives on the seabed, feeding on small invertebrates.
Dibranchus atlanticus was first formally described in 1872 by the German zoologist Wilhelm Peters with its type locality given as near the coast of Western Africa at a depth of 360 fathoms (2,160 ft; 660 m). [4] When he described D. atlanticus Peters proposed the new monospecific genus Dibranchus for it, it is now the type species of Dibranchus by monotypy. [5] The genus Dibranchus is classified within the "Indo-Pacific clade" of the family Ogcocephalidae. [6] 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 . [7]
Dibranchus atlanticus is the type species of the genus Dibranchus, a name which prefixes di, meaning "two", on to branchus, meaning "gills", a reference to the only the second and third gill arches having gills, the fourth having no gill filaments. The specific epithet atlanticus, means "of the Atlantic". [8]
D. atlanticus has a disc-shaped, vertically compressed body with a flat ventral surface, and grows to a standard length of 145 mm (6 in). The dorsal fin, which is set far back near the tail, has no spines and five to seven soft rays, and the anal fin has no spines and four soft rays. The pectoral fins are robust and held at right angles to the body; they are limb-like and are used to "walk" over the seabed, and the more slender pelvic fins serve the same purpose. [9] Under the operculum there is a sturdy multi-pointed spine. The bases of the fins, apart from the dorsal fin, are decorated with tubercles (cone-shaped scales) and the ventral surface of the disc is covered by distinct scales. The dorsal surface of the fish is usually a uniform reddish-grey, but specimens in the eastern Atlantic sometimes have reticulated markings. The ventral surface is paler. [3] [9] [10]
D. atlanticus is found in both the western and eastern Atlantic Ocean. Its range extends from the coasts of Canada and the United States, southwards through the Caribbean Sea and Gulf of Mexico to South America, as far south as Rio de Janeiro. In the eastern Atlantic its range includes northwestern Ireland and extends southwards to the Gulf of Guinea and Angola. Its depth range is from 45 to 1,300 m (150 to 4,270 ft), but it is most common between 300 and 823 m (1,000 and 2,700 ft). It is a bathypelagic species found on the seabed on muddy and sandy sediments. [3]
This fish may be bioluminescent, as there has been a report that in the laboratory, its skin can emit flashes of light when stimulated with peroxidase, but this effect has not been observed in living specimens. [11] It lures prey to the vicinity of its mouth; [1] its diet consists of small invertebrates such as polychaete worms, amphipods, clams, starfish, brittle stars and sea spiders. [3]
This deep sea fish is of no interest to commercial fisheries but it is often caught in deep water trawl surveys and appears to be common. The International Union for Conservation of Nature has listed it as being a "least-concern species". [1]
The orbicular batfish, also known as the cooper batfish, circular batfish, orbiculate batfish, round batfish, narrow-banded batfish or orbic batfish is a species of marine ray-finned fish belonging to the family Ephippidae, the spadefishes and batfishes. This species is found in the Indo-Pacific but has been recorded outside its native range in the western Atlantic Ocean.
Members of the genus Lophius, also sometimes called monkfish, fishing-frogs, frog-fish, and sea-devils, are various species of lophiid anglerfishes found in the Atlantic and Indian Oceans. Lophius is known as the "monk" or "monkfish" to the North Sea and North Atlantic fishermen, a name which also belongs to Squatina squatina, the angelshark, a type of shark. The North European species is Lophius piscatorius, and the Mediterranean species is Lophius budegassa.
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 sargassum fish, anglerfish, or frog fish is a species of marine ray-finned fish belonging to the family Antennariidae, the frogfishes, the only species in the genus Histrio. It lives among Sargassum seaweed which floats in subtropical oceans. The scientific name comes from the Latin histrio meaning a stage player or actor and refers to the fish's feeding behaviour.
The spotfin frogfish, also known as the big-spot angler, coin-bearing frogfish, darkspot frogfish, ocellated angler, ocellated fringed fishing frog, opulent frogfish, spotfin angler or white-finger anglerfish, is a species ray-finned fish belonging to the family Antennariidae, the frogfishes. The spotfin frogfish is found in scattered locations the eastern Atlantic, Indian and western Pacific Oceans.
The ocellated frogfish is a species of marine ray-finned fish belonging to the family Antennariidae, the frogfishes. This fish is found in the Western Atlantic Ocean.

Ogcocephalus radiatus or the polka-dot batfish is an arrow-shaped fish in the family Ogcocephalidae with an elongated thin tail. It is dorso-ventrally flattened with round pectoral fins that sit flat on the bottom of the sea floor. It uses its pectoral fins and pelvic fins to "walk" along the bottom in a side-to-side shuffling motion.

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.
