[8] [9] [10] A nauplius eye is completely absent. [11] After mating, mystacocarids lay tiny eggs which hatch into a nauplius or metanauplius larva. [ 4 ] Like the adults, the larvae are benthic.
Podocopid ostracods have just a naupliar eye consisting of two lateral ocelli and a single ventral ocellus, but the ventral one is absent in some species. [17] [25] [26] Platycopida was assumed to be completely eyeless, but two species, Keijcyoidea infralittoralis and Cytherella sordida, have been found to both possess a nauplius eye too. [27]
The nauplius is also the stage at which a simple, unpaired eye is present. The eye is known for that reason as the "naupliar eye", and is often absent in later developmental stages, although it is retained into the adult form in some groups, such as the Notostraca. [3] [4] Some crustacean groups lack this larval type, isopods being one example. [5]

Facetotecta is a poorly known subclass of thecostracan crustaceans. [1] The adult forms have never been recognized, and the group is known only from its larvae, the "y-nauplius" and "y-cyprid" larvae. [2]
Nauplius (larva), a life stage of crustaceans; Nauplius, a genus in the family Asteraceae; Nauplius, a genus of copepods, considered synonymous with Cyclops; Nauplius, a genus of shrimp, considered synonymous with Alpheus; Nauplius, an academic journal covering carcinology
Members of the Branchiopoda are unified by the presence of gills on many of the animals' appendages, including some of the mouthparts.This is also responsible for the name of the group [1] (from the Ancient Greek: βράγχια, gills, akin to βρόγχος, windpipe; Greek: πούς, foot). [2]
It follows the nauplius stage. In sac-spawning krill, [ Note 1 ] there is an intermediary phase called pseudometanauplius , a newly hatched form distinguished from older metanauplii by its extremely short abdomen .
