2. This larva develops from Protozoa. 3. The body is divisible into cephalothorax and a long segmented abdomen. 4. The cephalothorax is covered over by carapace and bears paired compound eyes and paired appendages e.g., antennules, antennae, mandibles, maxillae and maxillepedes and five pairs of gills. 5.

The first larval stage for crabs, lobsters, shrimp, barnacles, copepods, and some other crustaceans is called a nauplius. The nauplii of different species all look alike so they are hard to tell apart. These larvae live in the water column as part of the zooplankton. They’re stealthy little creatures in that they blend in with many zooplankton.

These larvae live in the water column as part of the zooplankton. They’re stealthy little creatures in that they blend in with many zooplankton. Ø Larval stage is called nauplius. Classification of Crustacea: Sub-phylum Crustacea is divided into six classes: Class 1 : Branchiopoda Class 2 : Remipedia Class 3 : Cephalocarida Class 4 : Maxillopoda Class 5 : Ostracoda 6. Mostly hermaphrodite; the young hatch as nauplius larva.

Class Branchiopoda Early Devonian to present; limbs usually leaflike; maxillae reduced; eyes sometimes stalked, usually sessile (unstalked), often fused to form a single large median eye; nauplius, but some with direct development; predominantly freshwater, some marine, and some in strong inland brines; about 900 species. La larve nauplius est la larve la plus simple libérée lors de l’éclosion des œufs chez les crustacés.Cette forme larvaire s’observe dans toutes les classes, soit sous forme libre soit comme étape parfaitement identifiable du développement embryonnaire. Barnacles were originally classified by Linnaeus and Cuvier as Mollusca, but in 1830 John Vaughan Thompson published observations showing the metamorphosis of the nauplius and cypris larvae into adult barnacles, and noted how these larvae were similar to those of crustaceans.
