The duration of the egg stage All models indicate that the nauplius stage suffers higher mortality as compared to copepodite stages or adults. Waves or peaks of mortality were detected for all The earliest and most basic type of a crustacean larva is the nauplius which has 6 developmental stages. In nauplii, development in the 1st naupliar stage is helgolandicus and Centropages typicus. Nauplii were raised from eggs to copepodites and the experiments were performed with stages NIV-NV. Gut evacuation.

The nauplii then molt into a juvenile "copepodite" stage, which has a form similar to the adult.

The free-swimming larva is oval and the body is divisible into three … Copepods hatch from eggs, spending the first part of their lives as a mite-like, larval "nauplius". The nauplii then molt into a juvenile "copepodite" stage, which has a form similar to the adult. The copepodites eventually develop into the adult form when they sexually mature. Larval development consists of six nauplius stages and a cyprid. Unilobed labrum with a prominent protuberance and the frontoiateral horns folded under the anterior cephalic shield margin are diagnostic features through all nauplius stages. The posterior border of the cephalic shield bears no posterior shield spines in nauplius stages IV‐VI. Life stages.

Chapter 7 _Peneus_ with its long direct development gave the best and truest picture of the ancestral history of the Malacostraca, and that accordingly the nauplius and the zoaea larvæ represented important In all Crustaceans the nauplius is the first larval stage of development. But its appearance-varies in different forms. In Cladocera, nauplius stage appears inside the egg. In Ostracoda nauplius, pair of bivalved shells and uniramous appendages is present. In the Cirripedia, a number of spines are present in the nauplius. The life cycle of Ergasilus briani is shown to consist of six nauplius stages, five copepodid stages and the adults. Only the adult female is parasitic.
