The genus name Nauplius was published posthumously by Otto Friedrich Müller in 1785 for animals now known to be the larvae of copepods. The nauplius stage (plural: nauplii) is characterised by consisting of only three head segments, which are covered by a single carapace. The posterior body, when present, is unsegmented.
A fertilised egg hatches into a nauplius: a one-eyed larva comprising a head and a telson with three pairs of limbs, lacking a thorax or abdomen. This undergoes six moults, passing through five instars , before transforming into the cyprid stage.
Nauplius (mythology), in Greek mythology, the son of Poseidon and Amymone, the father of Palamedes, and also the name of an Argonaut; Nauplia, a harbor town in Greece;
After switching off the aeration in the hatching tank, cyst shells will float and nauplii will concentrate at the bottom of the tank. The nauplii are further concentrated in a concentrator rinse and separated from the cysts. The enrichment process, if needed, generally occurs after the nauplii develop a digestive tract. [1]
When the egg arrives in a suitable pool, a larva hatches out at the nauplius stage (the nauplius stage is absent in Cyclestherida). [5] Clam shrimp nauplii are distinguished by very small front antennae. At the second stage (metanauplius), the larva develops the small shell. They develop very quickly.
Copepods (/ ˈ k oʊ p ə p ɒ d /; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat.Some species are planktonic (living in the water column), some are benthic (living on the sediments), several species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as ...

The nauplius larvae (sometimes absent) can be both lecithotrophic (non-feeding) and planktotrophic (feeding), and is followed by a larval stage called the cyprid, which is always lecithotrophic. The cypridoid larvae are referred to as the y-cyprid in the Facetotecta, the a-cyprid in the Ascothoracida , and the c-cyprid, or just cyprid, in the ...
