Ecology Summary - Nerita versicolor

Ecology of Nerita versicolor

Main Ref.	Poutiers, J.M., 1998
Remarks	Very common in the upper part of shores, often in crevices and pits of rock benches, or on branches of littoral trees overhanging the water. Moves up and down the shore in correlation with the prevailing high water level of the tide and can withstand heat and desiccation for long periods (Ref. 349). Nocturnal. Grazes on surface film of very fine marl particles, detritus, algae, flagellates, diatoms and nematodes (Ref. 96894).
