Short description Morfologia | Morfometria

Spine dorsali (totale): 13; Raggi dorsali molli (totale): 10; Spine anali 7; Raggi anali molli: 9; Vertebre: 13.

Biologia     Glossario (es. epibenthic)

Juveniles found in mangrove areas and seagrass flats; adults in protected waters such as lagoons and bays in the vicinity of rocky substrata or reefs. Forms schools that diminish with age, down to 10-25 fish by adult stage, although congregations may consist of several thousand fish during spawning period. Feeds by scraping encrusting algae from beach rock or pavement areas of coral reefs or by browsing on larger coarse algae. Common in markets where it is sold fresh (Ref. 9813).
