4. Fish is able to eat a wide variety of food. The food is broken down by the esophagus The food is further digested in the stomach The liver and pancreas add enzymes and chemicals The intestine completes the tract.

5. Fish get oxygen from the water not the atmosphere Fish use gills to breathe Gills are protected under the operculum Oxygen is absorbed by a thin membrane which covers the gills At the same time carbon dioxide is being released from the blood

6. Closed Circulatory System Heart Pumps in a single loop From the Heart to Gills From the Gills to the rest of the body From the body back to the heart Two-chambered heart.

7. Waste is released as ammonia Gills Kidneys Saltwater Fish loose water Special Kidneys

8. Small brain to body size Sharks has large brains Fore Brain Mid Brain Hind Brain Brain Stem

9. Exerting force Achieved by contracting muscles Flexion Vector Forces Lateral Movement

10. Spawning Females lay eggsReproduction Males Fertilize Seed is milt or soft roe Most species spawn in the same place

11. Agnatha: Chondrichthyes: Osteichthyes: Hag Fish Great White Shark Yellow Fish Tuna Fish

12. Catfish have 27,000 taste buds (humans have 7,000) There are over 30,000 species of fish Tuna fish can swim up to 43 mph Over 1,000 fish threatened by extinction Sharks and Rays do not have swim bladders.
