Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 12; Radios blandos dorsales (total) : 10; Espinas anales: 3; Radios blandos anales: 8; Vértebra: 24. This species is distinguished from all its congeners by the following set of characters: body deep and becoming compressed and slender with growth; D XII,10; the first 2 dorsal-fin spines rudimentary (2 dorsal-fin spines on first dorsal pterygiophore), third dorsal-fin spine longest (1.3-1.6, mean 1.4, in 3DFS/4DFS), thirrd not reaching beyond level of origin of first soft dorsal-fin ray and not greater than head length; orbit diameter subequal to suborbital depth. Colouration: body uniform pink, silvery belly and chin; spinous dorsal fin yellowish pink, other fins are yellowish pink or pale pink; cheek and region above the eye with bluish tinge; upper jaw often with yellowish orange tinge (Ref. 124569).
Found over corals in warmer waters and rocky reefs over sandy bottoms; feeds on benthic invertebrates (Ref. 5213, 124569). Sold fresh, whole or dried in markets (Ref. 3507).
