Ecology of Rochia nilotica

Main Ref.	Poutiers, J.M., 1998
Remarks	Typically found in shallow, high energy portions of barrier and reefs (Refs. 349, 128042). Feeds on filamentous algae and generally avoids bottoms of sand and living corals. Population density generally decreasing in deeper areas, while the mean size of individuals increases (Ref. 349).
