Max length : 50.0 cm TL maschio/sesso non determinato; (Ref. 7251); common length : 15.0 cm TL maschio/sesso non determinato; (Ref. 55763)
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 13 - 15; Spine anali: 0; Raggi anali molli: 13 - 15. Pelagic juveniles with spots, particularly prominent on belly; adults with dark blotches across back and spots between the blotches; fins without spots (Ref. 4423). 14 to 16 spines in an approximate row between snout and origin of dorsal fin; with a large brown bar above and below each eye; a broad transverse brown bar on occipital region of head (Ref. 13442).
Body shape (shape guide): short and / or deep.
Inhabit shallow reefs to open, soft bottoms. Also in areas with rocky substrata. Sometimes form groups (Ref. 9710, 48637). Occur on open muddy substrates as well as on rich soft-bottom and coral reefs. Juveniles often with floating Sargassum rafts. Young and sub-adults may form small groups (Ref. 48637). Benthopelagic (Ref. 58302). Juveniles pelagic to about 6-9 cm. Solitary. Feed on mollusks, sea urchins, hermit crabs, and crabs at night (Ref. 9680). Relatively poor swimmers (Ref. 9710). Used in Chinese medicine (Ref. 12166). Captured at the surface using a hand net (Ref. 26165).
