Nauplius (larva) — 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 developed yet.

Nauplius is a homologous developmental stage shared by all crustaceans, and the free-living form of nauplius has persisted in most lineages (Williams 1994b) but see Scholtz (2000). Despite being a conserved larval stage, the body forms of free-living nauplii are diverse ( Dahms et al. 2006 ; Martin et al. 2014 ), and differences in swimming behaviors have been reported ( Gauld 1959 ; Moyse 1984 ). Most of the 800 species of barnacles are very small. Barnacles start life as a free swimming larvae called a nauplius. The nauplius has an single-shelled exoskeleton, antennae, and six jointed legs.

You can recognize the larva of the barnacle by the two little 'horns'. After the Nauplius stage has lived some time swimming in the coastal plankton it undergoes a surprising transformation.

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 the use of the appendages of the head (the antennae) for swimming. The nauplius is also the stage at which a simple, unpaired eye first appears.

The carapace of Cirripedia projects backward from the head, consisting of several calcareous plates enclosing the body. The pelagic phase of the barnacle life cycle consists of two larval forms. The first form, the nauplius, undergoes a series of molts producing four to six planktotrophic or lecithotrophic naupliar stages (Strathmann, 1987).

Owing to positive phototaxy of early nauplius stages, hatched nauplii were concentrated to the corner of aquarium using a desk lamp. Then larvae were transferred

Nauplius barnacle

The first attempt to describe the nauplius larvae presented here had been undertaken in the unpublished PhD thesis of one of the authors (Fayers, 2003). There and in a later publication only briefly mentioning these larvae, the nauplii were addressed as "branchiopod nauplii [] almost certainly belonging to the anostracan lineage" (Fayers and Trewin, 2004).

But we know that small barnacles are visible upon whales within days or weeks of their arrival in the lagoons. Thus the conclusion is that these whale barnacles have a brief egg brooding period. The eggs develop into a form called nauplius or nauplius larvae. FEEDING APPARATUS OF BARNACLE NAUPLIUS 323 The mandibles From the common basal segment of each mandibl A) a stoue (PIt gnathobas.
