On the other hand, the life of early postembryonic stages is subject to different selection pressures. Nauplii, therefore, have undergone remarkable adaptive radiation within the limits of their organizational constraints. Because the nauplius stage is lost in several malacostracan taxa, the concept of the nauplius as a phylotypic stage of crustaceans is refuted. In addition, the nauplius as an example of the recapitulation of ancestral characters is discussed. Nauplius, the earliest stage of barnacle larvae is what was observed. They are Arthropods in the class Crustacea, which means they are related to lobsters and crabs, they both have a hard cover. A way to identify them from copepod larvae is to observe two small horn looking things on from side (Egmond 1999).
