Summary

Description

Black sea bream is oval in outline. Adults are a large (35-40 cm), silvery fish, although some have 6-9 dusky, vertical bars on the sides. It has a single long dorsal and anal fin and a large, slightly forked tail. The mouth is small and the jaws are equal in length. The profile of the head is smoothly convex in the young but changes to concave in mature males. Nesting males are often almost black in colour. Juveniles usually have numerous broken yellow stripes along the sides and a dark edge to the tail.
