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 0.5mm and 5mm 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!
