Comments: An inshore marine species which lives in shallow bays and sandy inlets near river mouths (Ref. 2156).  Found most frequently over sand, rocks and weeds in clear to turbid waters.  By day, cobblers are most often found in holes and on ledges in banks (Ref. 6390).  They are opportunistic feeders, primarily feeding at night.  Food consists of bivalve and univalve mollusks, crustaceans (small prawns and amphipods), polychaete worms, algae and organic debris (Ref. 26551).  Juveniles eat more crustaceans, often from among drifting macrophytic algae (Ref. 26548).  Adults feed mainly on mollusks and polychaetes (Ref. 6390).  They are prey to birds such as cormorants and pelicans (Ref. 26548).  Presence of sharp spines on the dorsal and pectoral fins can inflict painful wounds (Ref. 2156).
