The larval stages of the pink shrimp Penaeus duorarum BURKENROAD reared in the laboratory are described and compared with earlier descriptions of this species. While there are fundamental similarities with the earlier descriptions, this experiment has revealed differences in the number of naupliar stages and in setal formation of each stage. The larval development of the pink shrimp is very similar to that of the brown shrimp Penaeus californiensis HOLMES on the Pacific coast.
