Ctenochaetus strigosus, the kole tang, spotted bristletooth, spotted surgeonfish, goldring bristletooth, goldring surgeonfish, yelloweye tang or yellow-eyed surgeonfish, is a species of marine ray-finned fish belonging to family Acanthuridae which includes the surgeonfishes, unicornfishes and tangs. This fish is endemic to Hawaii.

Taxonomy

[edit]

Ctenochaetus strigosus was first formally described in 1828 as Acanthurus strigosus by the English zoologist Edward Turner Bennett with its type locality given as the Sandwich Islands.[3] In 1884 Theodore Gill classified A. strigosus in the new monospecific genus Ctenochaetus, meaning that it is the type species of that genus by monotypy.[4] 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.[5]

Etymology

[edit]

Ctenochaetus strigosus has the specific name strigosus, meaning "slender", probably an allusion to the many thin bristle-like teeth of this fish.[6]

Description

[edit]

Ctenochaetus strigosus has its dorsal fin supported by 8 spines and between 25 and 28 soft rays while its anal fin is supported by 3 spines and 22 to 25 soft rays.[2] The body is laterally compressed and it has a small mouth. The overall color is purplish to brown with slender, longitudinal light blue lines and a yellow ring around the eyes.[7] This species has a maximum published standard length of 15 cm (5.9 in).[2]

Distribution and habitat

[edit]

Ctenochaetus strigosus is endemic to the Hawaiian Islands and to Johnston Atoll in the United States Minor Outlying Islands.[1] It is a benthopelagic species found at depths between 1 and 113 m (3 ft 3 in and 370 ft 9 in) over coral, rock and rubble where it lives singly and feeds by sifting food, such as diatoms and algae, detritus in its bristle-like teeth.[2]

Utilization

[edit]

Ctenochaetus strigosus is a popular fish in the aquarium trade, it is one of the most heavily collected species in that trade in Hawaii. It is also an important species in recreational fisheries.[1]
