He did not explain why he altered the classification; Kemp's idea was quite new to important Japanese species of Sergestes has a free nauplius larva is sound.
Orbit and classification. Nauplius is a dark Jupiter trojan in a 1:1 orbital resonance with Jupiter. It is located in the leading Greek camp at the Gas Giant's L 4 Lagrangian point, 60° ahead on its orbit (see Trojans in astronomy). It is also a non-family asteroid of the Jovian background population.
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. nauplius larva The first, free-swimming, planktonic larva of most marine and some freshwater crustaceans.

No connexion with the nauplius eye is found. Each cell of the organ has microvilli, two nuclei, dictyosomes, and large cisternae of the endoplasmic reticulum. Except for the binucleated condition, the cells closely resemble the retinula cells of the copepod nauplius eye.

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.

the nauplius morphology is here proposed as valid to identify species. Some morphological features of the specimens
In consequence, the nauplius is not a phylogenetically "old" larval type, but represents a new type that first occurred in the stem-species of Eucrustacea. Using this information, the present material with its specific morphological features can be interpreted as comprising eucrustacean nauplius larvae . 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

Presence of a fourth pair of appendages (first maxilla of the adult) in addition to the original three pairs of the Nauplius is observed.
Barnacles were originally classified by Linnaeus and Cuvier as Mollusca, but in 1830 John Vaughan Thompson published observations showing the metamorphosis of the nauplius and cypris larvae into adult barnacles, and noted how these larvae were similar to those of crustaceans.
