Description

''Caesio suevica'' has a moderately slender, fusiform and laterally compressed body. The jaws, vomer and palatines have small conical teeth. The

dorsal fin A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found ...

of . These fishes are light silver blue, with fine gray stripes. The back shows a yellow line starting at the base of the dorsal fin. Ventrally they are paler. The tip of each caudal-fin lobe has a black blotch bordered by a white band.

Distribution and habitat

''Caesio suevica'' is endemic to the Red Sea records from elsewhere in the Indian Ocean are probably misidentifications. The Suez fusilier inhabits coastal areas, especially on coral reefs, at a depth from 2 to 25 m.

Biology
