  1. Classifying Fish Understanding the Classification of Fish and the Vertebrate Animal Kingdom

  2. Classifying Vertebrates • Objectives Understand the classification and identification of the animal kingdom Become confident with the organization of fish in the animal kingdom

  3. Organization of Vertebrates The vertebrates of the animal kingdom are divided into five main groups. Choose one of the three groups that are cold blooded to learn more about them. 1. Fish 2. Amphibians 3. Reptiles

  4. FishThe Water Dwellers Most fish are cold blooded vertebrates that live in water. Scientists believe that fish were the only vertebrates on Earth for about 150 million years. Scientists classify fish living today into three classes.

  5. Classes of Fish • Jawless • Cartilage • Bony

  6. Jawless Fish Jawless fish have a round mouth, tube like body, single fins, no scales, and a skeleton made of cartilage.

  7. Which of the Following is a Jawless Fish? Click on a picture to see if you are correct!

  8. Correct! The Sea Lamprey is a jawless fish that inhabits the Great Lakes region. Click here to return to Classes of Fish Return to Organization of Vertebrates

  9. Incorrect The shark is a cartilage fish. Unlike the jawless fish, the cartilage fish have movable jaws, scales, paired fins, and skeletons made of cartilage. Try again!

  10. Incorrect The Tuna is a bony fish.Bony fish have scales, well-developed sense organs, fins, and skeletons made of bone. Try again!

  11. Cartilage Fish Cartilage fish have movable jaws, scales, paired fins, and skeletons made of cartilage.

  12. Which of the Following is a Cartilage Fish? Click on a picture to see if you are correct!

  14. Incorrect The Sea Lamprey is a jawless fish. Jawless fish have a round mouth, tube like body, single fins, no scales, and a skeleton made of cartilage. Try again!

  15. Incorrect The Tuna is a bony fish.Bony fish have scales, well-developed sense organs, fins, and skeletons made of bone. Try Again!

  16. Bony Fish Bony fish have scales, well-developed sense organs, fins, and skeletons made of bone. See if you can identify a bony fish!

  20. Correct The Tuna is a bony fish.Bony fish have scales, well-developed sense organs, fins, and skeletons made of bone. Try Again!

  21. AmphibiansLiving in Water and on Land Amphibians spend part of their lives in water and part on land. They have moist, smooth skin that allows for the exchange of oxygen and carbon dioxide. They are cold-blooded. The three types of amphibians that exist today are frogs and toads, salamanders, and caecilians. Return to Organization of Vertebrates

  22. ReptilesThe Move to Land Reptiles are cold blooded and have thick, dry, waterproof skin covered with scales. As a reptile grows, its skin is shed by molting. The four orders of reptiles living today are turtles, alligators and crocodiles, lizards and snakes, and tuataras.
