2018-05-16 · Crustaceans begin life as an egg and then go through a series of larval stages, molting several times, before reaching adulthood. The first larval stage for crabs, lobsters, shrimp, barnacles, copepods, and some other crustaceans is called a nauplius. The nauplii of different species all look alike so they are hard to tell apart.
Cirripede, any of the marine crustaceans of the infraclass Cirripedia (subphylum Crustacea). The best known are the barnacles. Adult cirripedes other than barnacles are internal parasites of marine invertebrates such as crabs, jellyfish, and starfish, and have no common name.

The discovery of true nauplii is of significance, as the fossil record of confidently identified nauplii is very scarce and, besides the presented specimens, confined to fossils in 'Orsten Stanley I. Dodson, David G. Frey, in Ecology and Classification of North American Freshwater Invertebrates (Second Edition), 2001. A. Life History. Notostracans begin life as nauplii or metanauplii which hatch out of eggs, often resting eggs. Non-cladoceran branchiopods use a variety of signals to begin development from the egg, including day length, salinity level, temperature, and oxygen concentration. A nauplius consists of three pairs of appendages (the antennules, antennae), and a single eye in the middle of the anterior portion of their body (median eye or naupliar eye). This eye is sometimes retained in the adult form. Naupli have a cephalic shield or the beginnings of the dorsal carapace, and no segmentation on the trunk.
A typical crustacean nauplius has three pairs of legs and an unpaired simple eye. Additional pairs of appendages and paired compound eyes… Read More; reproduction

nauplius larva The first, free-swimming, planktonic larva of most marine and some freshwater crustaceans. It has no evident segmentation. There is a single, median, nauplius eye at the front of the head. There are only three pairs of appendages, the first and second antennae, and the mandibles.
Classification of Crustacea: Sub-phylum Crustacea is divided into six classes: Class 1 : Branchiopoda Class 2 : Remipedia Class 3 : Cephalocarida Class 4 : Maxillopoda Class 5 : Ostracoda 6. Mostly hermaphrodite; the young hatch as nauplius larva. Examples: lepas (goose barnacle), Balanus (acorn barnacle), Synagoga, Proteolepas, Sacculina, etc.
