Short description
Dorsal spines (total): 7 - 9; Dorsal soft rays (total): 13 - 16; Anal spines: 0; Anal soft rays: 13 - 17; Vertebrae: 37 - 42. Identified by the four bony protuberances on the top of the head (the protuberances are smaller in females and young and absent in the freshwater form), the chainlike lateral line, the sharp spines on the preoperculum, and the absence of palatine teeth. Gill rakers reduced to rounded, spiny protuberances. Soft dorsal often much enlarged in adult males; caudal truncate to slightly rounded. Young gray above, with three or four dark saddles below dorsal fins and a dark spot on dorsal side of caudal peduncle; adults are darker; spiny dorsal fin dusted with black; soft dorsal, anal, pectoral and caudal fins have dark bars; pelvic fins pale.
Biology
Occurs in cold brackish and moderately saline water near the coast; enters coastal rivers and may occur as far as 120 miles inland. Maximum depth reported at 100m. Benthic . Movements are limited to short onshore-offshore seasonal movements and mass movements of fry into shallow water in autumn. Moreover, there are no migrations of large numbers; movement into freshwater and long distances up rivers are apparently undertaken by relatively few individuals at a time. Diurnal from November to April but is largely nocturnal the rest of the year. Feeds on small crustaceans, fishes and molluscs. Spawning takes place in shallow waters, male digs a groove in the gravel where pairing and egg laying occur. Move to deeper water in the spring, where they stay in summer
