Ctenochaetus flavicauda, the whitetail bristletooth or redspotted tang, is a species of marine ray-finned fish belonging to the family Acanthuridae which includes the surgeonfishes, unicornfishes and tangs. It is found in the western central Pacific Ocean.
Taxonomy
[edit]Ctenochaetus flavicauda was first formally described in 1938 by the American zoologist Henry Weed Fowler with its type locality given as Takaroa in the Tuamotu Islands of French Polynesia.[2] The type specimen was collected on the George Vanderbilt South Pacific Expedition of 1937.[3] The genera Ctenochaetus and Acanthurus make up the tribe Acanthurini which is one of three tribes in the subfamily Acanthurinae which is one of two subfamilies in the family Acanthuridae.[4]
Etymology
[edit]Ctenochaetus flavicauda has the specific name flavicauda, meaning "yellow tail", which is a reference to what Fowler described as its "brilliant yellow caudal fin", although subsequent authors have described the caudal fin as pure white.[5]
Description
[edit]Ctenochaetus flavicauda has its dorsal fin supported by 8 spines and between 26 and 28 soft rays while its anal fin is supported by 3 spines and 23 to 26 soft rays. This species has a maximum published total length of 16 cm (6.3 in).[6] The overall colour is reddish marked with many blue spots on the head and these change into blue lines on the body.[3] The brilliant white caudal fin contrasts sharply with the rest of the body.[5]
Distribution and habitat
[edit]Ctenochaetus flavicauda occurs in the central Pacific Ocean from the Phoenix Islands north to the Line Islands, east to the Pitcairn Islands, south to the Austral Islands and Rapa Iti.[1] It is found on coral reefs down to depths of 30 m (98 ft).[6]
