Appearance

Ocean surgeons are known by their oval bodies with uniform color , the pale to dark marking around the eyes, and the light yellow is now found on their bodies. Most have blue or white markings on the dorsal fin, anal fin, and tail fins and pale bands can sometimes be seen at the base of their tails. They often swim in schools with other species such as the Atlantic blue tang surgeonfish. They have been recorded up to 38 cm in length .
Ocean surgeons have a total of 9 spines on their Dorsal fins and between 23 and 26 soft rays. Their anal fins have only 3 spines and between 21 and 23 rays. Their caudal fins are roughly emarginate, and the surgeonfish's body and head are both deep and compressed.

These fishes are mainly blue but may have some dark blotches, such as this one. The name surgeon is because of the scalpel-like sharp spines on each side of their tail base. Acanthurus bahianus,Caribbean Netherlands,Geotagged,Ocean surgeon,Summer
