A nauplius (plural nauplii) is the first larva of animals, classified as crustaceans. Nauplius larvae belong to the phylum Arthropod. It body consists of a thorax and abdomen, head and telson* 1. This organism has a single, median eye at the front of its head.

The nauplius eye and frontal organs in Crustacea / by Rolf Elofsson Elofsson, Rolf, 1930- (författare) Lund, 1966 Engelska 12 s. Although the crustacean nauplius eyes can be divided into four morphotypes, including the typical maxillopodan nauplius eye, they always have both pigment and sensory cells in pairs (Elofsson, 2006). On the other hand, both the pigment and the sensory cells appear before tapetal cells in the embryonic development of eyed-species, as shown in the present study. The nauplius eye in several families within the Eucyphidea is more complicated than generally believed. It consists of a nauplius eye s. s.
