Il corpo del nauplius è suddiviso nelle seguenti parti: La testa; Il telson; Tre paia di appendici, che nell'individuo adulto diventeranno le antennule, le antenne e le mandibole. Il torace e l'addome non sono sviluppati nella larva nauplio. Nauplius larva occurs in the development of all the crustaceans and so it was considered as the ancestral form of crustaceans. The old idea of recapitulations stands greatly modified now-a-days and the crustacean larval forms are now regarded to be the larval reversions of simpler crustacean ancestors. ADVERTISEMENTS: In this article we will discuss about the nauplius, zoea and megalopa larva of crustaceans with the help of suitable diagrams.

It has no evident segmentation. There is a single, median, nauplius eye at the front of the head.

The Nauplius larva is the first planktonic larval However mouth and alimentary canal are lacking in nauplius of Cirripedia. The larva is without a heart and a segmented ventral nerve cord. METANAUPLIUS. It follows the nauplius, is a vaguely defined stage. It consists of an oval cephalothorax, an elongated trunk-region and an abdomen terminating in a caudal fork provided with setae. Nauplius larvae are released by contractions of the externa and develop after several molts into a cypris larval stage, which metamor-phoses into an adult after fixation on a suitable host crab. The systematic positions of S. carcini and other Rhizo-cephala have been enigmatic.
