Naupli (nauplius is the singular, naupliar is descriptive), are the first and most This eye is sometimes retained in the adults and it referred to as a naupliar eye.

In addition to the optic nerve from the compound eyes, the protocerebrum of A. salina receives an input from the nauplius eye and the frontal organ (Fig. III.3.1;Elofsson 1966, Rasmussen 1971

The components of the nauplius eye differentiate into adult ocelli (Takenaka et al., 1993). Larvae also develop a pair of compound eyes that appear only in the late nauplius … 2020-01-01 This eye, located atop the head, may have a lens and sense the direction of light but does not see images. In later stages, two more capable compound eyes develop on the sides but the initial eye may also stay, becoming the "third eye" of the creature. Nauplii may prefer to swim towards the light." The ex te rna l space is the haemocoel (H).

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 is composed of 1 ventral and 2 dorsal ocelli.

nauplius eye: translation (Order Stomatopoda): Minute, unpaired light-sensitive organ on ocular plate between eyestalks (ocular peduncles) [Stachowitsch, 1992]. Artemia is a genus of aquatic crustaceans also known as brine shrimp. Artemia, the only genus in the family Artemiidae, has changed little externally since the Triassic period. The first historical record of the existence of Artemia dates back to the first half of the 10th century AD from Urmia Lake, Iran, with an example called by an Iranian geographer an "aquatic dog", although the first Relatively simple, median eye, typically consisting of 3 photoreceptor units (up to 7 in taxa where it persists in the adult) and first appearing in the nauplius larval stage.
