Gill rakers reduced to rounded, spiny protuberances (Ref. 27547). Soft dorsal often much enlarged in adult males; caudal truncate to slightly rounded (Ref. 27547). 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 (Ref. 27547).
