Ecology Summary - Lethrinus lentjan

Language:

Main Ref.	Carpenter, K.E. and G.R. Allen, 1989
Remarks	Adults generally solitary and found in deeper water (Ref. 2295). They prefer sandy or gravelly areas (Harris et al, 1992). Juveniles appear to live in shallow, inshore waters such as seagrass and mangrove areas, the fish moving into deeper water as they age (Ref. 27260, 28202, 41878). In the Great Barrier Reef, L. lentjan is a frequent inhabitant of mid-shelf reefs (0-15 m depth), and only an occasional inhabitant of coastal fringing reefs and mid-shelf reefs of greater than 15 m depth (Newman & Williams, 1996). Invert. feeders (Ref. 41878). Demersal. Dwells in sandy bottoms near coral reefs. Feeds on shrimp, small crabs, mollusks, marine worms and small fishes (Ref. 9773).
