Ecology Summary - Leptoscarus vaigiensis

Language:

Main Ref.	Bruce, R.W. and J.E. Randall, 1985
Remarks	Occurs inshore (Ref. 75154). Inhabits seagrass areas or areas with hard substrates heavy with algal cover (Ref. 30573). Present in seagrass beds at all life stages (Ref. 41878). Feeds on seagrasses and algae (Ref. 30573). Inhaca Island is a seagrass epibiont so it is possible that its ingestion of sponge and unidentified Hydrozoa are unintentional along with the seagrass (Ref. 42227). In Nakagusuku Bay, Okinawa Island, all larvae ranging from 1.0-1.5 cm SL, fed only on planktonic copepods. Food shifted from planktonic copepods in postflexion larvae and juvenile ranging from 1.0-1.5 cm SL to seaweed in the juvenile ranging from 1.5-2.5 cm SL (Ref. 54487). Food shifts in adult and young over 2.5 cm SL to feed almost exclusively on drifting Sargassum spp. (Ref. 54487).
