Morphology | Morphometrics
Females light greenish gray, becoming pinkish ventrally, with diffuse orange-red stripe from behind eye to base of caudal fin; a broad white area over abdomen, the lower part with vertical lines of red; there may be faint red bars on the body. Large adult males lose the distinctive red, white and black markings; they develop a vertically elongate blue spot on each body scale; a yellow head with near-vertical pale blue bands, and a large dark spot in axil of pectoral fins (Ref. 13442).
Western Atlantic: southern Florida, USA and Bahamas to northern South America.
Most common in open sandy areas. Feeds on small sand-dwelling invertebrates. Dives head first into the sand when frightened. Generally common (Ref. 9710). Generally of no interest to fisheries because of its small average size (Ref. 5217).
