nauplius [ naw-plee- uhs ] noun, plural nau·pli·i [naw-plee-ahy]. (in many crustaceans) a larval form with three pairs of appendages and a single median eye, occurring usually as the first stage of development after leaving the egg.

See: nauplius eye [McLaughlin, 1980]. Sessile unpaired eye of nauplius larva which persists in some adults. (Syn. naupliar eye) [Moore and McCormick, 1969]. Term sometimes used to refer to a naupliar eye; see naupliar eye [Brusca and Brusca,… 2021-04-16 · nauplius eye A single median eye comprising three- or four-pigment cup ocelli, sometimes with a lens, probably enabling the organism to determine the direction of a source of light for orientation.

Nauplius eyes of the species listed in Table 1 were observed using a transmission electron microscope. Common ostracod and copepod species bear the typical type of maxillopodan nauplius eye, whereas most cavernicolous or interstitial species have not only lost their eyes, but also its anlage. Notes on the development of the nauplius eye and fronatl organs of decapod crustaceans Elofsson, Rolf LU ( 1966 ) In Acta universitatis Lundensis Sectio II 27 . p.1-21 Mark The nauplius for is maintained through three further stages of growth and moulting, resulting after 10-14 days in a stage VI nauplius. The short, broad body of nauplius (see the picture and figure above) results mainly from a precocious development, in functional larval form, of the anterior part of the head. In lab experiments, individuals of T. californicus show no preference between areas exposed only to photosynthetically active radiation (PAR) or shade, but aggregate in the shaded portion of a tank when exposed to UV‐B.

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.

Abstract The present investigation concerns the nauplius eye and frontal organs in decapod Crustaceans. Representatives from all groups of the Decapoda are included. Some of the more important results are abstracted. The nauplius eye in several families within the Eucyphidea is more complicated than generally believed. It consists of a nauplius eye s. s. with three cups and three sensory cells
