10  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).

11  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!
