Light brown dorsally and white ventrally; large dark bar above and below eye and on occipital region of head; large dark blotch above pectoral fin base and on base of dorsal fin; dorsal section of body and posterior part of head covered with small, round, dark spots; fins light yellow and lack spots
Distribution
Western Atlantic from Massachusetts to Brazil, including the entire Gulf of Mexico, the Bahamas, and the Antilles
Habitat Associations
Tropical to warm temperate seas; from near shore to 100 m; larvae and juveniles to 90 mm TL are pelagic, large juveniles and adults are demersal
More common in the vicinity of mangrove areas than on reefs
Biology
Gastropods, crabs, other crustaceans, and sea urchins
Maximum known size is 300 mm TL
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).
Reproductive mode: dioecism; fertilization: external; nonguarders; parental care: none.
