				Life cycle and mating behavior				
					Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae				
			
			
				
					Members of the order Isopoda are mostly gonochoric.  Mating behavior:  Mating usually occurs before and sometimes during the parturial molt.  Sperm transfer is indirect.  Life cycle:  Eggs are brooded in the marsupium, which later hatch into manca postlarva before developing into adults.
