The nauplius eye in Cyclestherida, Laevicaudata and Spinicaudata (previously collectively termed Conchostraca) consists of four cups of inverse sensory cells separated by a pigment layer and a tapetum layer. There are two lateral and two medial cups, a ventral medial cup and a posterior medial cup.

N2 - The nauplius eye and frontal organs in the Malacostraca have been investigated. The present work is a direct continuation of the author's investigation of the same organs in decapod malacostracans (Elofsson, 1963).

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.

Abstract The present work is a continuation of the morphological studies of the nauplius eye and frontal organs of the Crustacea. The previous papers on this topic comprised the Decapoda (ELOFSSON, 1963) and the Malacostraca (ELOFSSON, 1965).

It is composed of 1 ventral and 2 dorsal ocelli. A single eye appears in front of the two foremost "feet;" and a mouth, stomach, and intestine are discovered within this little body.

The pre­ sent work is a direct continuation of the autho:r's investigation of the same organs in decapod malacostracans (ELOFSSON, 1963). The results ubtained confirm the recognition of a nauplius eye sensu latu and a nauplius eye sensu strictu.

"Nauplius: A nauplius (plural nauplii) is the first larva of animals classified as crustaceans (subphylum of Arthropoda).It consists of a head and a telson.The thorax and abdomen, characteristic of adult crustaceans, have not yet developed.. A prominent characteristic of nauplii is that they have only one (non-facetic) eye (the so-called naupliar eye).This eye, located atop the head, may have

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.
