Dorsale stekels (totaal) : 9 - 10; Dorsale zachte stralen (totaal) : 12 - 14; Anale stekels: 3; Anale zachte stralen: 10 - 12. Diagnosis: elongate fish with 2 separate dorsal fins and a rather deep caudal peduncle; vomerine teeth patch anchor-shaped, with the posterior teeth extending to the midline of palate; scales on interorbital space ctenoid; opercle with 2 flat spines; lower preopercular margin with large, forward-pointing spines; caudal fin moderately forked; scales small (Ref. 57391).
Coloration: silvery grey, back bluish in life; juveniles and adults with small dark markings scattered over back and sides; a very distinct black spot on opercle (Ref. 57391).
Body shape (shape guide): fusiform / normal.
Coastal species (Ref. 4197), found in coastal marine and brackish waters (Ref. 57391). Occurs on various kinds of bottoms, including sand, muddy sand and rocks; occasionally occurring in rivers (Ref. 6916, 57391). Also capable of living in hypersaline habitats (Sine Saloum in Senegal)(Ref. 57391). Feeds mainly on shrimps and mollusks, also fishes (Ref. 5990).
