Taggstrålar i ryggfenan (totalt): 14; Mjukstrålar i ryggfenan (totalt): 11; Taggstrålar i analfenan 3; Mjukstrålar i analfenan: 10. Deep-bodied wrasse with a strongly arched dorsal profile. First 3 dorsal spines filamentous. Only wrasse with elongate dorsal spines and such a highly arched profile (Ref. 26938). Color variable but generally mottled brownish red with a black spot at rear base of dorsal fin (Ref. 13442).
A large and economically valuable species, monandric and a protogynous hermaphrodite (Ref. 93709). Adults are found over open bottoms or coral reef areas (Ref. 5217). Often encountered where gorgonians are abundant (Ref. 13442). Feed mainly on mollusks, also crabs and sea urchins (Ref. 3726). Flesh highly esteemed; marketed fresh and frozen (Ref. 3726). Have been reared in captivity (Ref. 35420).
Monandric (no primary males) , protogynous hermaphrodites. Sex change is postmaturation; it is initiated among individuals 30-40 cm LF (or 3-5 yrs) but was also observed in fish as large as 69.4 cm LF (13 yrs). Sex change occurred after one more spawning (as a female) seasons and requires several months to complete (Ref.74380). Harem spawner (Ref.74381). Spawning activity is characterised by the following event called 'spawning rush': 1) pectoral swim up, 2) tail swim, 3) swin alongsode and tilt, 4) release, 5) circle and display, and 6) swim down (Ref. 74381).
