Nauplius

 

the plankton larva of numerous species of the family Crustacea. The body is unsegmented and has three pairs of appendages. In front of the mouth there are uniramous sensory antennules; in back there are biramous antennae and mandibles for swimming. The nauplius has a median eye. Between the mandibles and the anal opening there is a growth zone, where, as development progresses, the postnauplial segments with appendages develop.
