  4. Mammals Characteristics: • Have teeth • Have hair • Are warm blooded • Have a single jaw bone • Have inner ear bones • Produce milk for their young www.assignmentpoint.com

  6. Fish Characteristics: • Are cold-blooded vertebrate (backbone) • Live in water • Usually have paired fins, gills, and scales www.assignmentpoint.com

  7. Fish • Most fish lay large numbers of eggs, but some have live birth. • Most fish breathe by drawing water over four or five pairs of gills. www.assignmentpoint.com

  8. Amphibians Characteristics: • Are cold-blooded vertebrate (backbone) • Lay their eggs in water • Lack any skin coverings such as fur, scales or feathers www.assignmentpoint.com

  9. Amphibians • Young amphibians tend to resemble small fish. • Amphibian means "two lives," a reference to the change that frogs go through as they move from egg to tadpole to frog.  • Even as adults, most frogs and other amphibians must stay close to water.  www.assignmentpoint.com

  10. Birds Characteristics: • Have feathers • Lay eggs • Have bodies specially adapted for flight • Have a beak rather than teeth www.assignmentpoint.com

  11. Birds • Their nearly hollow bones provide lightweight strength. • Birds now live almost everywhere on Earth. www.assignmentpoint.com

  12. Reptiles Characteristics: • Have scales • Lay leathery eggs on land • Are often called cold-blooded because they can't regulate their own body temperature www.assignmentpoint.com

  13. Reptiles • Reptiles do not use energy to fuel internal "furnaces" • Although reptiles breathe through lungs, some reptiles can also absorb oxygen in water through their mouth. www.assignmentpoint.com

  14. Resources • Quia Classification Quiz • Charts: Animal classification, Fish, Bird, Amphibian, Animals, • The Animal Kingdom www.assignmentpoint.com
