Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 8 - 9; Radios blandos dorsales (total) : 25 - 27; Espinas anales: 3; Radios blandos anales: 23 - 25. Body purplish gray when alive; grayish brown when preserved; a region of dull yellow in front of eye, a lesser extension posterior to lower part of eye; outer 1/3 of pectoral fin yellow, extreme distal part hyaline; dorsal and anal fins yellowish grey basally, dull yellow distally; caudal fin base whitish; caudal fin purplish. Anterior gill rakers 16-24, posterior 17-22. Caudal spine small.

Biología     Glosario (por ej. epibenthic)

Live in various reef habitats, sand slopes and lagoons (Ref. 48637). Juveniles inhabit shallow, protected, turbid inshore waters while adults prefer deeper areas of protected bays and lagoons. Also in outer reef areas (Ref. 1602). Benthopelagic (Ref. 58302). Schooling species, feed on diatoms, detritus film of sand, filamentous algae, hydroids, and pieces of fish (Ref. 1602, 48637). Probably the only surgeonfish that readily takes bait (Ref. 12484).
