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. The median eye is typical of crustacean nauplius larvae. It may degenerate as the larva develops, or it may persist into the adult form.

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. Light detection in T. californicus is presumably by the nauplius eye, which is described at the histological and ultrastructural levels.

The retinula cells have large masses of It consists of a nauplius eye s. s. with three cups and three sensory cells in each and the incorporated dorsal frontal organ, which functions as an eye. The sensory cells are everse.The dorsal frontal organ is thus intimately connected with the nauplius eye s. s. and must not be mixed up with the eye papilla and the sensory pore X organ.The dorsal frontal organ is subjected to a considerable degree of variation. SummaryThe nauplius eye of the cyclopoid copepod Macrocyclops albidus has been studied by means of the electron microscope.

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. 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.

It occurs together with the ventral frontal organ in the Decapoda and the Stomatopoda. The nauplius eye s. s. and the dorsal frontal organ, though separated, occur in the Anaspidacea. The nauplius eye s. s. and the ventral frontal organ, separated as is always the case in the Malacostraca, occur in the Euphausiacea.
