Kole Tang
Ctenochaetus strigosusAlso known as Yelloweye Tang, Spotted Bristletooth, Goldring Surgeonfish, Yellow-eyed Surgeonfish
Kole tangs play a vital role in Hawaiian reef ecosystems by using their specialized, comb-like teeth to scrape fine algae and detritus off rocks and corals. These active surgeonfish are easily recognized by the bright yellow ring around their eyes and a body covered in delicate spots and thin, horizontal stripes. They spend their days constantly grazing, helping to prevent algae from smothering the living coral reef.
