  1. KINGDOM ANIMAL • PHYLUM: CHORDATA • SUBPHYLUM: VERTEBRATA

  2. VERTEBRATES ANIMALS WITH: Dorsal nerve cord Hollow backbone Ventral heart

  3. 5 major classes • Classified by: • Skin covering • Heart chambers • Reproduction • Type of limbs • How they maintain body temperature

  4. HOMOLOGOUS STRUCTURESshow relationships

  5. ChondrichthyesSharks, rays • Skin covering: teeth • Two chambered heart • External or internal fertilization • Limbs – fins • Cold blooded, aquatic

  6. Skate egg capsule

  7. For a bowl of soup, we alter the ecosystem

  8. OstheicthyesBony fish • ectothermic(cold blooded), aquatic vertebrates. • skin is covered with scales. • limbs - finsfor swimming. • breathe with gills. • External fertilization - lay eggs that must be in water.

  9. AMPHIBIANSFROGS, TOADS, NEWTS, SALAMANDERS • ectothermic vertebrates. • skin is either smooth (like a frog) or rough (like a toad). • dependent upon moisture and subject to desiccation; their skin must remain moist to aid in breathing • lay eggs in water, which hatch into an intermediate life form (tadpole or larva) that usually breathes with gills, and change into the adult form that breathes air and can live outside water. • three-chambered hearts. • lack claws on their toes.

  13. RED SPOTTED NEWT

  14. SALAMANDER

  15. REPTILESSnakes, lizards, turtles, gators • ectothermicvertebrates. • skin has scales, but no hair or feathers. • three-chambered hearts (except for alligators and crocodiles, which have four-chambered hearts). • claws on their toes • first animals, in evolution, to develop the amniotic egg. This allows reptiles to lay eggs on land.

  16. Amnionic Egg (shelled egg)

  17. copperhead

  18. rattlesnakes

  19. Pygmy rattlesnake

  20. BIRDS • endothermic vertebrates. • skin is covered with feathers. • four-chambered hearts. • bones are lightweight and usually hollow. • forelimbs are modified as wings. • lay eggs.

  21. MAMMALS • endothermic vertebrates. • Body covered with hair, which varies greatly among species. • Most have sudoriferus (sweat) glands. • have mammary (milk-secreting) glands. • sebaceous (fat-secreting) glands. • have heterodont dentition (different types of teeth).
