  2. 6-3.1 Compare the characteristic structures of invertebrate animals and vertebrate animals Blue Ridge Middle School 6th Science Mrs. Bright BRMS 6th Science Mrs Bright

  3. Animal Kingdom Has 35 different Phyla (Phylum) Chordate Phylum 34 invertebrate Phyla Has 5 Classes of Vertebrates Mammal Bird Amphibian Fish Reptile Warm Blooded Vertebrates Cold Blooded Vertebrates

  4. Common Characteristicsof all Animals • Their bodies are multi-cellular • They are heterotrophs • Their main functions are: • To obtain food & oxygen for energy • Keep internal conditions in balance (homostasis) • Move • Reproduce

  5. Phylum ChordataVERTEBRATES • Have backbone, internal skeleton (Endoskeleton) and muscles. • Have blood that circulates through vessels and lungs (or gills) for breathing.  • Have protective skin covering •  Have a nervous system with a brain that processes information from their environment through sensory organs. • Most have legs, wings, or fins for movement

  6. Fish • Are ectothermic • Obtain dissolved oxygen in water through gill • Have scales • Have fins • Live in water • Most lay eggs

  7. Fish Sea Ray - Chondrichthyes Lamprey – Jawless Fish Catfish - Osteichthyes Whale Shark - Chondrichthyes

  8. Amphibians 1.Ectothermic 2.Most can breathe in water as young, and breathe on land with lungs as adults.

  9. Amphibians Go through metamorphosis Lay jelly-like eggs Frogs, toads, salamanders

  10. Amphibians (Frogs and Salamanders) Frogs and salamanders have smooth, moist skin through which they breathe. Live part of life in water and part on land

  11. Big ol’ Salamanders!!!

  12. Amphibians (Toads) Have thicker, bumpy skin Live on land

  13. Amphibians Spotted Salamander Poison Dart Frog Caecilian Fire Bellied Toad

  14. The Life Cycle of a Frog Amphibians Adult Frog Adults are typically ready tobreed in about one to two years. Young Frog Frog eggs are laid in water and undergo external fertilization. The eggs hatch into tadpoles a few days to several weeks later. Fertilized Eggs Tadpoles Tadpoles gradually grow limbs, lose their tails and gills, and become meat-eaters as they develop into terrestrial adults.

  15. Reptiles • Are ectothermic • Breathe with lungs • Most lay eggs, although in some the eggs hatch inside the female • Have scales or plates.

  16. Brown Watersnake

  17. Reptiles Sea Turtle Coral Snake Galapagos Tortoise Tuatara

  18. Birds • Are endothermic • Breathe with lungs • Lay eggs • Have feathers • Have a beak, two wings, and two feet.

  19. Birds Purple Finch Stork Emu Red-Tailed Hawk

  20. Mammals • Are endothermic • Breathe with lungs • Most have babies that are born live • Have fur or hair • Produce milk to feed their young.
