CLASSIFICATION
Different Classes � � Malacostra- crabs, lobsters, shrimp krill etc Ostracoda- ostracods Maxillopoda- barnicles Branchiopoda – brine shrimp
HOW CRUSTACEANS ARE CLASSIFIED. � � � A hard exoskeleton Compound Eyes Antennae The abdominal segments have swimmerets (swimming legs) The circulatory system is open. The nervous system consists of a primitive ventral nerve cord and ganglia system (similar to those of an earthworm).
Fun Facts � � � Open Circulatory System Lobsters have teeth-like structures in their stomach, which grind partially digested food. The structure is called a gastric mill. Some species of shrimp are luminescent, meaning they produce a faint light. Copepods are small crustaceans, between 0. 5 mm and 5 mm in length. Male fiddler crabs have one large claw, which they wave in the air to impress females when trying to find a mate and intimidate other males and predators. The waving of their claw is thought to resemble playing the Fiddle!
