Short description Morfologia | Morfometria

Spine dorsali (totale): 8; Raggi dorsali molli (totale): 13-14; Spine anali 3; Raggi anali molli: 11. Body without longitudinal stripes. Initial phase body yellow with light vertical red lines. Terminal phase body abruptly blue to blue-green behind pink and green head. Reddish vertical lines on body. Pectoral fins yellow on basal half, blue to black distally (Ref 9823).

Biologia     Glossario (es. epibenthic)

Occurs in groups (Ref. 90102) in clear outer lagoon and seaward reefs, over open sand and rubble as well as dense coral growth. Common is shallow exposed areas (Ref. 9710). Benthopelagic (Ref. 58302). Feeds mainly on shelled benthic invertebrates (crabs, shrimps, gastropods, bivalves, brittle stars, sea urchins), also on polychaete worms and fish eggs.
