				Inhabits rivers, creeks, lakes and ponds in plains.  Also occurs in mouths of rivers draining into lagoons, in rocky shores of rivers and irrigation creeks, and in floodplain pools.  Deposits its eggs into host mussels (Ref. 78070).			
			 
			
			
			
				
				
				
				Female has an ovipositor which is used to deposit eggs inside bivalves. Young remain in the bivalve until they can swim (Ref. 43281).
