					Used as food by coastal populations of oceanic islands in the West Pacific (Ref. 349). 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).				
			
			
			
			
			
				Life cycle and mating behavior				
					Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae				
			
			
				
					Members of the order Neritopsina are mostly gonochoric and broadcast spawners.  Life cycle:  Embryos develop into planktonic trocophore larvae and later into juvenile veligers before becoming fully grown adults.
