Description
The yellowback fusilier is a small to medium-sized fish which grows to about 40 cm (16 in) long. The mouth is small and terminal and is protusible, being able to be extended forward to swallow food. The body is fusiform or spindle-shaped. The dorsal fin has 10 spines and 14–15 soft rays. The anal fin has three spines and 11 or 12 soft rays. The caudal fin is deeply forked. The body coloration is greyish blue with a bright yellow zone on the back. The yellow area goes from the forehead, between the eyes, to the tail, and includes the dorsal fin and the caudal fin. This area corresponds more or less to the upper third of the body. The belly is plain white.
Range & habitat
Caesio xanthonota is widely distributed throughout the tropical waters of the Indian Ocean, the Red Sea and Persian Gulf excluded, to Indonesia in the western Pacific Ocean. It lives in mid-water in deep lagoons and close to external reefs from the surfaceto 50 m deep.
