					Frequently collected in the area for food and for the shell which is traditionally used as a decorative item in many parts, or as container for liquids by the natives of the South Seas (Ref. 349). Live in colonies.  During periods of activity, lift their shell straight up to move forward, then drop it down.  Often partially buried below the surface of sand when inactive or during feeding.  Preys on the crown-of-thorns Acanthaster planci, which is recently responsible for the devastation of many coral reefs (Ref. 349).				
			
			
			
			
			
				Life cycle and mating behavior

					Members of the order Neotaenioglossa are mostly gonochoric and broadcast spawners.  Life cycle:  Embryos develop into planktonic trocophore larvae and later into juvenile veligers before becoming fully grown adults.
