- 5. IntroductionVertebrates can be classified or grouped into five categories. These are:1. Birds2. Fishes3. Amphibians4. Reptiles5. Mammals
- 6. BirdsBirds are warm-blooded creatures that lay eggs. All birds have feathers and wings, and most birds are able to fly. Birds are can varied in their shapes, sizes, colors, and behavior patterns.
- 7. FactThere are more than 9,000 different species of birds in the world.
- 9. FishesFishes come in an amazing variety of shapes and colors, but they all have three important things in common: All fishes live in water, have fins, and use gills to get oxygen from the water. Â
- 11. AmphibiansAmphibians are animals that live part of their life in water and part on land. Even those species that lay eggs on land start life in a fluid-filled egg, breathing through gills.
- 13. ReptilesToday there are 6,800 reptile species on earth; the major groups are alligators , crocodiles, turtles, lizards, and snakes. All reptiles are cold-blooded, which is why they warm themselves in the sun, and have bodies covered in dry scales. Some reptiles lay eggs; others give birth to live young.
- 15. MammalsMammals live on land, at sea, in the air, and under the ground. All mammals, from bats to whales, share a number of important traits that make them different from other animals. Mammals are warm-blooded, they have fur or hair, and most mammals give birth to live young (rather than laying eggs).
