- Larval stage in ontogeny of some decapods preceding zoea stage. [Moore and McCormick, 1969]
- The second in a series of free-swimming larval stages of a penaeid shrimp. [Bliss, 1982]
- (Taxon-specific: Order Decapoda) Third of basically five larval stages (nauplius, metanauplius, protozoea, zoea, postlarva). Applied to shrimp-like (natantian) decapod and characterized by antennal locomotion. May be subdivided into several substages. Protozoea of certain forms termed elaphocaris. [Stachowitsch, 1992]
