Maturity: Lm ? range ? - ? cm
Max length : 50.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 7251); common length : 15.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 55763)
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 13 - 15; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 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).
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).
