Tetrabrachiidae, or the four-armed frogfishes or doublefin frogfishes, is a small family of marine ray-finned fishes belonging to the suborder Antennarioidei in the order Lophiiformes, the anglerfishes. These fishes are found in relatively shallow waters of the eastern Indian Ocean and western Pacific Ocean.
Tetrabrachiidae was first proposed as a subfamily, the Tetrabrachiinae, of the family Antennariidae in 1912 by the English ichthyologist Charles Tate Regan with only a single genus included, Tetrabrachium, a monospecific genus which had been proposed by Albert Günther in 1880. [2] In 2009 a second monospecific genus, Dibrachichthys , was added to the family when it was described by Theodore Wells Pietsch III, Jeffery W. Johnson and Rachel J. Arnold. [3] The Tetrabrachiidae is classified within the suborder Antennarioidei within the order Lophiiformes, the anglerfishes. [4] This family is regarded, with its sister taxon the Antennariidae, as the most derived clade within the suborder Antennarioidei. [5]
Tetrabrachiidae is derived from its type genus Tetrabrachium, which means "four armed", a reference to the pectoral fins having their upper parts separate, giving the impression of there being two pectoral fins on either side of the body. [6]
Tetrabrachiidae contains the following two monospecific genera: [7] [8]
Tetrabrachiidae frogfishes have an elongate and strongly compressed body with a small mouth and a convex nape. They have no swimbladder. The soft dorsal fin is supported by 16 or 17 soft rays while the anal fin is supported by 11 soft rays. There are no teeth on the palatine. [4] The small, closely set eyes are set high on the head and protrude above the dorsal profile. The illicium, or fishing rod, has no esca, or lure. [9] It was thought that the pectoral fin being divided was a characteristic of the family but Dibrachichthys has undivided pectoral fins. [3] Four-armed frogfishes are small fishes, the largest species is Tetrabrachium ocellatum which has a maximum published standard length of 7 cm (2.8 in). [7]
Tetrabrachiidae frogfishes are found in the western Pacific and eastern Indian Oceans around northern Australia, New Guinea and Indonesia. [4] These fishes occur in areas of soft substrate in inshore waters and the continental shelf. [10]
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 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.
Glauert's anglerfish is species of marine ray-finned fish belonging to the subfamily Histiophryninae in the family Antennariidae, the frogfishes. This species is the only species in the monospecific genus Allenichthys. This species is endemic to southern Australia.
Histiophryne is a genus of marine ray-finned fishes belonging to the subfamily Histiophryninae in the family Antennariidae, the frogfishes. These fishes are found in waters ranging from Taiwan to South Australia. There are currently five known species. These fishes are easily distinguished from other anglerfishes as having a reduced luring appendage, a highly evolved form of the first dorsal fin spine.
Fowlerichthys is a genus of marine ray-finned fishes belonging to the family Antennariidae, the frogfishes. The fishes in this genus are found the Atlantic, Indian and Pacific Oceans.
Kuiterichthys is a genus of marine ray-finned fishes belonging to the subfamily Histiophryninae in the family Antennariidae, the frogfishes. These fishes are endemic to Australia.
Lophiocharon is a genus of marine ray-finned fishes belonging to the subfamily Histiophryninae in the family Antennariidae, the frogfishes. These fishes are found in the eastern Indian Ocean and Western Pacific Ocean.
Nudiantennarius is a monospecific genus of marine ray-finned fish belonging to the family Antennariidae, the frogfishes. The only species in the genus is Nudiantennarius subteres, the deepwater frogfish. This fish is found in the Western Pacific Ocean.
Phyllophryne is a monospecific genus of marine ray-finned fish belonging to the subfamily Histiophryninae in the family Antennariidae, the frogfishes. The only species in the genus is Phyllophryne scortea, the white-spotted anglerfish, smooth anglerfish or smooth frogfish, which is endemic to southern Australia.
Rhycherus is a genus of marine ray-finned fishes belonging to the subfamily Histiophryninae in the family Antennariidae, the frogfishes. The fishes in this genus are endemic to the waters off Australia. This genus is classified in the monogeneric family Rhycheridae, the Balrog frogfishes, by some authorities.
Dibrachichthys is a monospecific genus belonging to the family Tetrabrachiidae, the four-armed frogfishes. The only species in the genus is Dibrachichthys melanurus, the twoarm humpback anglerfish, which is found in the eastern Indian and western Pacific Oceans.
Porophryne is a monospecific genus of marine ray-finned fish belonging to the subfamily Histiophryninae in the family Antennariidae, the frogfishes. The only species in the genus is Porophryne erythrodactylus, the red-fingered anglerfish, red-footed frogfish, Bare Island anglerfish or Sydney anglerfish, which is endemism to the waters off New South Wales in eastern Australia. Both the species and the genus were first described in 2014.
Antennarius indicus, the Indian frogfish, is a species of marine ray-finned fish belonging to the family Antennariidae, the frogfishes. The Indian frogfish is found in the Indian Ocean.
Fowlerichthys avalonis, the roughbar frogfish or roughjaw frogfish, is a species of marine ray-finned fish belonging to the family Antennariidae, the frogfishes. This fish is found in the Eastern Pacific Ocean, where it is the most widespread frogfish species.
Echinophryne crassispina, the prickly anglerfish, prickly frogfish or thick-spined anglerfish, is a species of marine ray-finned fish belonging to the subfamily Histiophryninae in the family Antennariidae, the frogfishes. These fishes are endemic to the temperate waters of southern Australia.
Echinophryne mitchellii, the long-spined frogfish, bristly frogfish, Mitchell's anglerfish, Mitchell's frogfish, prickly angler fish or spinycoat anglerfish, is a species of marine ray-finned fish belonging to the subfamily Histiophryninae in the family Antennariidae, the frogfishes. These fishes are endemic to the temperate waters of southern Australia.
Lophiocharon trisignatus, the spot-tail anglerfish, rough anglerfish or three-spot frogfish, is a species of marine ray-finned fish belonging to the subfamily Histiophryninae in the family Antennariidae, the frogfishes. This fish is found in the Indo-Pacific region.
Antennarioidei is a suborder of marine ray-finned fishes belonging to the order Lophiiformes, the anglerfishes.
Abantennarius is a genus of marine ray-finned fishes belonging to the family Antennariidae, the frogfishes. The fishes in the genus are found in the Indian, Pacific and, one species, in the Western Atlantic Oceans.
