The nauplius is the earliest free-living stage in the development of most crustaceans, except in the majority of the. Malacostraca. Several character states of the 

Naupli (nauplius is the singular, naupliar is descriptive), are the first and most commonly observed larval stage (image, left). Producing naupliar larvae is a characteristic often used to identify crustaceans, however there are a few groups that do not produce naupliar larvae. Early Larval StageVWR offers slides for the varied purposes of your lab. Prepared and digital microscope slides for educational purposes are featured in an array of fields.

The body becomes larger and more elongated in shape as it develops into later stages. Of the six nauplius stages, the first two stages, N1 and N2, are typically non-feeding [32].

Variations in the density proportions of each develop mental stage - nauplius, copepodite, and adult - of T. japonicus, in numbers of individuals per millilitre, are shown in figure 9. Chapter 7 _Peneus_ with its long direct development gave the best and truest picture of the ancestral history of the Malacostraca, and that accordingly the nauplius and the zoaea larvæ represented important

The five stages of development are • Stage I (immature/undeveloped) – ovaries Nauplius • Nauplius stages are 6 from N1 to N6, • Distal inner lateral seta long,  After this stage it changes into a cyprid larval stage and then anchors itself onto a substrate as an adult barnacle.

The Nauplius larva is the first planktonic larval stage of most marine and some freshwater crustaceans. he main features of a nauplius are a simple, unsegmented body, three pairs of appendages (antennules, antennae, and mandibles), and a single median eye.

Larval nursery is a crucial period that determines the success in culture of Litopenaeus vannamei, the most productive shrimp species in world aquaculture industry.

Nauplii have limited swimming ability and usually are a part of the oceanic plankton. The next stage is marked by the devlopment of first segment of the pleopods development. The mysis remain drifting in the water column until they metamorphose into post larvae within 10–12 days. Fig. 15. Migratory pattern burrowing species of shrimps.
