Shows the external anatomy of a living crayfish and using a freshly anesthetized specimen points out its internal anatomy by systems.  Presents its hard exoskeleton, body divisions, and the jointed nature of its appendages. The exoskeleton is removed from an anesthetized crayfish showing its beating heart and abdominal muscles. Blood circulation is traced and specific structures involved are identified. The reproductive systems of male and female crayfish are shown and the paths of sperm and eggs are traced. The path of food through the digestive system is discussed as the function of each organ involved is explained. The green glands and excretory system are pointed out along with the brain and nervous system.
