The Kole or Yellow Eye Tang, Ctenochaetus strigosus .......
One of six genera of acanthurids, Ctenochaetus comprises six of the seventy-two described species of Surgeonfishes. Specialized mouths and teeth, in the Greek, cteno-chaetus means "comb bristle" define the genus’ members. Unlike other surgeons that have rigid, attached dentition, Ctenochaetus have movable, individual, bristle-like teeth. Coupled with a protrusible, outreaching mouth, these fishes use this unusual feeding device to sort and remove interstitial fauna, scrape soft algae, and "detritus" of nutritive value from rock and substrate.
