 The white head bar is thick and located just behind the eyes.A large white abbreviated saddle shape or slanted white bar across the middle of the fish's body makes it quite obvious to see how it got the name "Saddleback".In some varieties, typically those specimens initially associated with "Heteractis crispa" anemone, the saddle shape may extend up onto the fish's Dorsal fin with a third white bar or margin located across the caudal peduncle, (pictured in taxobox).
