Acanthurus achilles

It is thought that the name refers to Achilles, the mythical hero of the Trojan War, and may be an allusion to the sharp bony plates on the caudal peduncle.

[6] Acanthurus achilles has an elongated oval-shaped body with a steep dorsal profile to the head.

The small, protrusible mouth is positioned low on the head with between 8 and 28 teeth fixed on each jaw, each having a flattened, serrated tip.

The overall colour is bluish-black with an irregular oval orange blotch on the rear of the body, a white bar on the gill cover, a wide orange bar on the caudal fin which also has a white posterior margin.

[2] Acanthurus achilles is found in various reefs of Oceania, up to the islands of Hawaii and Pitcairn.
