TAXONOMY

Kingdom: Animalia

Phylum: Chordata

Class: Actinopterygii (ray-finned fishes)

Order: Perciformes (Perch-likes)

Family: Acanthuridae (Surgeonfishes, tangs, unicornfishes)

DISTRIBUTION/HABITAT: Indo-Pacific: from East Africa to Hawaii and the eastern Central Pacific. Also from Southwest Japan to the Great Barrier Reef. Absent from most of the Central Pacific. Adults are found mainly on deep coastal reef slopes and outer reef walls.

Depth ranges from 4–131 m (4-430 ft) and are usually found below 30 ft..

 

DIET IN THE WILD: Grazes algae from reefs and sand.

 

IUCN Red List Least Concern

 

REMARKS: The eyestripe surgeonfish reputedly has a strong odor when cooked. The Hawaiian name for this fish is palani and a Hawaiian riddle based on this name means “odor reaching to heaven.” This species can quickly change its coloration to a much darker shade that obscures the yellow and markings.

 

A distinguishing feature of surgeonfishes, tangs, and

unicornfishes is a modified scale on the caudal peduncle, which forms a scalpel-like sharp blade often covered with toxic slime. These spines are used for species recognition, defense, and competition for mates. Note: Acanthus means “thorn” or “spine”.
