Post-larvae refer to the stage in the life cycle of certain marine organisms, particularly crustaceans like shrimp, after they have completed their larval development and metamorphosis. During this stage, the organisms transition from a free-swimming larval form to a more juvenile form, resembling the adult but not yet sexually mature. This phase is critical for growth and adaptation to benthic or juvenile habitats. Post-larvae are often studied in aquaculture and fisheries for their role in population dynamics.
Prawns go through three larval stages, the nauplius, zoea, and mysis. After this, they go through an intermediate phase called postlarvae, at which time they look pretty much like small adults and begin settling to the sea bottom.
A shrimp goes through several stages before it becomes an adult, each step has its own name as follows..... egg > nauplii > zoeae > myses > postlarvae > shrimp. This process takes about twelve days, more details can be found on the related link, under life cycle.

The common species of crayfish (crawfish) live about 2 or 3 years, but individuals may live to be as old as 8 years. Some rare species can live as long as 20 years.After reaching 2 years of age, they have usually grown fairly large and have difficulty creating larger shells beyond a certain size. Each new molting makes them more vulnerable to predators.
