Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 9; Mjukstrålar i ryggfenan (totalt) : 9; Taggstrålar i analfenan: 2; Mjukstrålar i analfenan: 8; Ryggkotor: 24. This species is distinguished by the following characters: pored lateral-line scales usually 9-10 and 14-16 gill rakers and rudiments on first gill arch; body scales with narrow dark margins; body uniform to mottled brownish without darker bars on sides (except at night); the second dorsal fin, anal fin and caudal fin pale are without darkish banding; pectoral fin with no whitish spot at axil; without whitish spots at base of caudal peduncle or behind posterior base of second dorsal fin; two darkish small marks near base of caudal peduncle (Ref. 93673).

Occurs among seagrasses, heavy algal growth, or rubble of shallow sheltered areas (Ref. 1602); sandy substrates (Ref. 76833). Readily enters brackish and also found in fresh waters (Ref. 27665). Benthic and benthopelagic (Ref. 58302).
