Arthropoda- Crustacea • Fossil Record and Evolutionary History • Structures – what makes them unique • Life Cycle & behaviour • Classification • Over 40,000 species classified under Crustacea
Behaviour • http://www.youtube.com/watch?v=i-ahuZEvWH8
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!
