Teeth usually small, densely distributed, and blunt-tipped. Very seldom fewer than 7 long gill rakers on anterior gill arch (except in Ophidiini). Dorsal and anal fins long, joined to caudal fin; dorsal-fin rays normally longer than opposing anal-fin rays; pelvic-fin rays 0-2. Scales present. A well-developed spine on opercle usually present. Anus placed posterior to tip of pectoral fin except in species with prolonged pectoral fins.
