Ecology Summary - Lethrinus nebulosus

Language:

Main Ref.	Carpenter, K.E. and G.R. Allen, 1989
Remarks	Adults occur alone or in small schools; juveniles form large schools in shallow, sheltered sandy areas. Juveniles appear to live in shallow, inshore waters such as seagrass (Ref. 41878) and mangrove areas, the fish moving into deeper water as they age (Ref. 27260, 28202). In the Gulf of Carpentaria, L. nebulosus associates with L. laticaudis usually in depths of greater than 30 m (Ref. 28202). Inhabits inshore, coastal waters associated with coral and rocky reefs. Forms small schools that are visible above reefs in an almost motionless state. Believed to be attributed to feeding as its diet consists of organisms suspended in the water column such as small crabs and marine worms (Ref. 9773).
