背面の脊椎 (合計): 6; 背鰭 (合計): 11-12; 肛門の骨 0; 臀鰭: 12. Dark bar under eye; tan in color, with dark spots above; sides with 6-10 vertical bars; large specimens with black margined dorsal and anal fins; caudal fin with oblique bands (Ref. 2798).
Restricted to sandy, quiet water areas and is unable to form burrows where the substrate is disturbed by water movements, is muddy or consists of sand with a particle diameter > 0.5 mm. Food consists of slow moving benthic organisms like chironomid larvae, gastropods, bivalves and amphipods. On exposed shores, they occur deeper than 3.5 m (Ref. 28077, 2798). Occasionally intertidal.
