Short description
Bestämningsnycklar | Morfologi | Morfometri
Body deep (less so with age) and strongly compressed; mouth small; jaw teeth small, villiform, and only slightly hooked, disappearing with age; lower branch of first gill arch with 8 to 10 gill rakers; dorsal fin with 6 spines followed by another spine and 24 to 27 soft rays (VI+I, 24-27); upper third of body dark; belly white; flanks with golden highlights; no distinctive marks (Ref. 55763).
Adults are found in coastal waters, usually forming schools in shallow inshore sandy areas (Ref. 9283). They feed on mollusks, crustaceans, other invertebrates and small fishes (Ref. 9283). Excellent for human consumption. Minimum depth range based on estimate; to be replaced with a better reference.
