plural nau·pli·i [naw-plee-ahy]. /ˈnɔ pliˌaɪ/.
- : a larval form with three pairs of appendages and a single median eye, occurring usually as the first stage of development after leaving the egg.

The three pairs of appendages of the nauplius larva (the future first and second antennae and mandibles).
The Nauplius at this stage gives rise to another larva form, the so-called Zoëa, which is of great importance.
But of all living crabs the Phyllopods are the most closely allied to the original primary form of the Nauplius.
One of the as yet unexplained features of the protaspis of trilobites is the absence of the "nauplius eye."
The development, although modified by the early appearance of the bivalved shell within which the nauplius lies, is direct.
