Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 10 - 13; Mjukstrålar i ryggfenan (totalt) : 11 - 14; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 9 - 10. Diagnosis: body oblong and compressed; dorsal profile slightly and regularly convex; snout shorter than eye diameter (Ref. 57395). Mouth large, oblique (Ref. 5377, 57395) and protrusible (Ref. 57395). Lower jaw slightly prominent; 2 anterior pores on chin, followed by a median pit bearing openings of two large pores (Ref. 57395). Eyes large (Ref. 5377). Dorsal fin deeply notched; caudal fin deeply forked; scales ctenoid on body and head (Ref. 57395).
Coloration: back olivaceous, sides silvery to white; dark spot at angle of opercle; sometimes several small, dark spots on dorsal-fin base (Ref. 57395). Fins grey (Ref. 5377).
Body shape (shape guide): fusiform / normal.
Inhabits coastal waters (Ref. 2683). Semipelagic, remains near the bottom during the day and moves up to the open water at night (Ref. 5377, 57395). Occasionally enters lagoons and estuaries at start of sexual maturation (Ref. 57395). Occurs over sandy and muddy bottoms. Feeds on invertebrates and small fishes (Ref. 5535).
