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.
