Ctenochaetus, or bristletooth tangs, is a genus of marine ray-finned fish belonging to the family Acanthuridae, which includes the surgeonfishes, unicornfishes and tangs. These fishes are found in the Indo-Pacific region. They have many, small flexible teeth and some species have the common name bristletooth.
Taxonomy
Ctenochaetus was first proposed as a genus in 1884 by the American biologist Theodore Gill with Acanthurus strigosus as its type species.[1] A. strigosus had originally been described in 1828 by Edward Turner Bennett from the Sandwich Islands.[2]
It has been proposed that this genus and Acanthurus should be merged as otherwise Acanthurus is paraphyletic.[3] The 5th edition of Fishes of the World recognises these two genera as valid and classifies them as the two genera in the tribe Acanthurini of the subfamily Acanthurinae within the family Acanthuridae.[4]
Species
There are currently nine recognized species in this genus:[5]
- Ctenochaetus binotatus J. E. Randall, 1955 (Twospot surgeonfish)
- Ctenochaetus cyanocheilus J. E. Randall & Clements, 2001 (Short-tail bristle-tooth)
- Ctenochaetus flavicauda Fowler, 1938 (whitetail bristletooth)
- Ctenochaetus hawaiiensis J. E. Randall, 1955 (Chevron tang)
- Ctenochaetus marginatus (Valenciennes, 1835) (Striped-fin surgeonfish)
- Ctenochaetus striatus (Quoy & Gaimard, 1825) (Striated surgeonfish)
- Ctenochaetus strigosus (E. T. Bennett, 1828) (Kole Tang)
- Ctenochaetus tominiensis J. E. Randall, 1955 (Tomini surgeonfish)
- Ctenochaetus truncatus J. E. Randall & Clements, 2001 (Indian gold-ring bristle-tooth)
