With a holistic view of naupliar performance in space, time, and evolution, Crustacean Nauplii is the first comprehensive volume dedicated to the study of this subject. This book contains the first identification key to the larvae of many groups of Crustacea. It provides comprehensive phylogenetic information and discusses the evolution of crustacean nauplius. Ideal for biotech scientists, the text incorporates more than 1200 citations to assist in further study. Additional coverage includes external anatomy of nauplii, functional morphology, embryonic development, variability of ontogenetic characters, naupliar diversity, and obstacles in the phylogenetic use of naupliar characters.
