As a shrimp grows, it sheds its exoskeleton to make a new one. This species is reared in circular holding tanks where they think they are in the open ocean, and swim in "never ending migration" around the circumference of the tank. The appendages are called pleopods or swimmerets, and can be used for purposes other than swimming. Each segment has a separate overlapping shell, which can be transparent. "On this basis, taxonomic classifications now divide the order Decapoda into the two suborders: Dendrobranchiata for the largest shrimp clade, and Pleocyemata for all other decapods.
