  4. AMPHIBIANS http://www.kidport.com/RefLib/Science /Animals/AnimalIndexV.htm REPTILES http://www.kidport.com/RefLib/Scie nce/Animals/Reptiles.htm FISH http://www.kidport.com/RefLib/Science /Animals/AnimalIndexV.htm BIRDS http://www.kidport.com/RefLib/Science/Animals/Birds.htm MAMMALS http://www.kidport.com/RefLib/Science/Animals/Mammals.htm VERTEBRATES

  5. Standard 6-3.1: Vertebrates • Animals with backbones • Vertebrates share other physical characteristics; for example • a protective skin covering • an inside skeleton • muscles • blood that circulates through blood vessels • lungs (or gills) for breathing. • Vertebrates have legs or fins for movement • Vertebrates have a nervous system with brains that process information from their environments through sensory organs, such as ears or tongues • Vertebrates also contain many highly developed systems associated with their specialized organs. • There are thousands of species of vertebrates divided into five groups: fish, amphibians, reptiles, mammals, and birds.

  6. FISH http://www.kidport.com/RefLib/Science /Animals/AnimalIndexV.htm Standard 6-3.1: Vertebrates - Fish • Fish have backbones • Fish are cold-blooded (ectothermic) • Fish obtain dissolved oxygen in water through gills • Most fish lay eggs • Fish have scales • Fish have fins • Fish live in the water Back To Lotus Diagram

  7. AMPHIBIANS http://www.kidport.com/RefLib/Science /Animals/AnimalIndexV.htm Back To Lotus Diagram Standard 6-3.1: Vertebrates - Amphibians • Amphibians have backbones • Amphibians are cold-blooded (ectothermic) • Amphibians can breathe in water with gills early in life, and breathe on land with lungs as adults • Amphibians go through metamorphosis and lay jelly-like eggs • The major groups of amphibians are frogs, toads, and salamanders • Frogs and salamanders have smooth, moist skin, through which they can breathe; and live part of their life in water and part on land. • Toads have thicker, bumpy skin and live on land.

  8. REPTILES http://www.kidport.com/RefLib/Scie nce/Animals/Reptiles.htm Standard 6-3.1: Vertebrates - Reptiles Back To Lotus Diagram • Reptiles have backbones • Reptiles are cold-blooded (ectothermic) • Reptiles breathe with lungs • Most Reptiles lay eggs; although in some the eggs hatch inside the female • Reptiles have scales or plates

  9. MAMMALS http://www.kidport.com/RefLib/Science/Animals/Mammals.htm Standard 6-3.1: Vertebrates - Mammals Back To Lotus Diagram • Mammals have backbones • Mammals are warm-blooded (endothermic) • Mammals breathe with lungs • Mammals have babies that are born live • Mammals have fur or hair • Mammals produce milk to feed their young

  10. BIRDS http://www.kidport.com/RefLib/Science/Animals/Birds.htm Standard 6-3.1: Vertebrates - Birds • Birds have backbones • Birds are warm-blooded (endothermic) • Birds Breathe with lungs • Birds Lay eggs • Birds have feathers • Birds have a beak, two wings, and two feet Back To Lotus Diagram

  11. What are three functions of a backbone? • The backbone supports the body, gives the body flexibility, and protects the spinal cord. Back To Lotus Diagram

  12. Explain how ectotherms and endotherms differ in the way they control their body temperature. • The body temperature of ectotherms changes depending on the temperature of environment. Endotherms have bodies that control internal body heat and therefore maintain nearly constant body temperature. Back To Lotus Diagram

  13. What two groups of present-day vertebrates are the descendants of reptiles? • Birds and mammals Back To Lotus Diagram
