Branchiostegus is a genus of marine ray-finned fishes, tilefishes belonging to the family Malacanthidae. They are found in the eastern Atlantic Ocean through the Indian Ocean to the western Pacific Ocean. [3] Here they create burrows in soft substrates in the comparatively deep waters of the continental shelf and slope. [4]
Branchiostegus tilefishes have a rectangular body shape with a square profile to the head. They have a raised seam situated to the anterior of the dorsal fin, this can be reduced but it is always there. They have a body which is around four times as long as it is deep. There are fine serrations on the preopercular upper arm while its lower arm has very few or no serrations and there is no spine at its angle. The operculum has a single flexible, blunt spine. The mouth is slightly angled and extend to the front of the eye. The dorsal and anal fins are long and unbroken. The dorsal fin has 6 to 8 spines, typically 7 and 14 to 16, normally 15, soft rays. The anal fin contains 2 spines and 11 to 13, typically 12, soft rays. The caudal fin is rounded, truncate, or double emarginate and sometimes has elongated tips. They have pelagic larvae which have many spines on their heads and serrated ridges. [5]
There are currently 18 recognized species in this genus: [3]
Branchiostegus was created by the French naturalist Constantine Samuel Rafinesque (1783-1840) in 1815, with Lacépède's Coryphaenoides hottuynii (now recognised as a synonym of Branchiostegus japonicus) as its type species. [2] The genus name is a compound of branchios meaning "gill" and stegos meaning "cover". Rafinesque put this name forward without explanation but he placed the genus in a subfamily of Lophionota, an unavailable name for a grouping which approximates to the currently recognised Coryphaenidae, in which he put dolphinfishes, sailfishes and many other marine fishes and which were distinguished by the possession of branchiostegal membranes. [1] The genus is currently placed in the subfamily Latilinae. [8]
Tilefishes are mostly small perciform marine fish comprising the family Malacanthidae. They are usually found in sandy areas, especially near coral reefs.
Hoplolatilus starcki, Stark's tilefish, purple-headed sand tilefish or bluehead tilefish, is a species of marine ray-finned fish, a tilefish belonging to the family Malacanthidae. This species is native to the central Indo-Pacific.
Caulolatilus cyanops, the blackline tilefish or ocean whitefish, is a species of marine ray-finned fish, a tilefish belonging to the family Malacanthidae. It is found in the western Atlantic Ocean.
The Gulf bareye tilefish, also known as the anchor tilefish, is a species of marine ray-finned fish, a tilefish belonging to the family Malacanthidae. It occurs in the western Atlantic Ocean.
Branchiostegus japonicus, the horsehead tilefish, Japanese horsehead tilefish, red amadai or the red tilefish, is a species of marine ray-finned fish, a tilefish belonging to the family Malacanthidae. It is native to the western Pacific Ocean.
The blue blanquillo, Malacanthus latovittatus, also known as the banded blanquillo, striped blanquillo, false whiting, sand tilefish or eye of the sea, is a species of marine ray-finned fish, a tilefish belonging to the family Malacanthidae. It is found in the Indo-Pacific.
Caulolatilus is a genus of tilefishes native to the Pacific and Atlantic coasts of the Americas. This genus is regarded as the least specialised and the most basal of the tilefishes.
Malacanthus brevirostris, the quakerfish, flagtail blanquillo, false whiting or stripetail tilefish, is a species of marine ray-finned fish, a tilefish belonging to the family Malacanthidae. It has a wide Indo-Pacific distribution.
Caulolatilus chrysops, the Atlantic goldeneye tilefish or gold face tilefish, is a species of marine ray-finned fish, a tilefish belonging to the family Malacanthidae. It occurs in the western Atlantic Ocean.
Caulolatilus hubbsi, the Hubbs's tilefish, is a species of marine ray-finned fish, a tilefish belonging to the family Malacanthidae. It occurs in the eastern Pacific Ocean. Its specific name honours the American ichthyologist Carl Leavitt Hubbs (1894-1979). Studies have shown that this taxon is not readily distinguishable from Caulolatilus princeps and should be treated as a junior synonym of C. princeps.
