  1. An animal that has, for at least one stage of their life, a dorsal, hollow nerve cord; a notochord; pharyngeal pouches; and a tail that extends beyond the anus. CHORDATES Cherokee Gettle, Jon McDonald, Nate Unger

  2. DifferentKinds of Chordates • Nonvertebratechordates • Fishes • Amphibians • Reptiles • Birds • Mammals

  3. NonvertebrateChordates ~Soft-bodied marine organisms that have a hollow nerve cord, a notochord, pharyngeal pouches, and a tail at some stage of their lives~ Lancelets Tunicates ~ fishlike creatures ~ live on sandy ocean bottoms ~ adults- defined head containing a mouth ~ pharynx/gills ~ gas exchange ~ closed circulatory system ~ muscles in v-shaped units/movement ~ filter-feeding ~ larva- all the chordate characteristics ~ adults- no notochord or tail

  4. Fish Aquatic vertebrates that are characterized by paired fins, scales, and gills ~ fins/movement ~ scales/protection ~ gills/exchanging gases ~ exception ~ First fish ~ The age of fishes ~ The arrival of jaws and paired fins ~ The rise of modern fish

  5. Amphibians • Ectothermicvertebraes • 3 chambered hearts • Lack of claws on toes • Webbed feet • Respiration: lungs, gills, skin • Eggs in water Blue Poison Frog

  6. Amphibians • Examples • AmericanBullfrog • Midwife Toad • Two-lined Salamander • Blue poison frog • Mexican Caecillian

  7. Reptiles • Ectothermicvertebraes • Scales • 3 chambered hearts • Lungs • Claws on toes • Amiotic egg

  8. Reptiles • Examples • Komodo Dragon • Coral Snake • Loggerhead turtle • Tuatara • American alligator

  9. Birds • Wings • Feathers • Hollow bones • Hind limbs are used for perching, walking, and swimming • Has a beak or bill, NO TEETH • No external sex organs

  10. Birds • They have 4 chambered heart • Lay eggs • Warm blooded • Eats seeds, fruits, insects, worms, small reptiles, and small mammals • Birds can eat up to 30% of their weight in one meal

  11. Birds Bald Eagle • Examples: • Bald eagle • Red tail hawk • Ring neck pheasant • Great horned owl • Robin • Morning dove Great Horned owl

  12. Mammals • Hair • Warm-blooded • Almost every mammals give live birth • Monotiemes- mammals that lay eggs • Marsupials- pouched mammals • Placental- the majority of the mammals, give live birth Giraffe

  13. Mammals • Examples • Duck billed platypus • Grizzly bear • Humans • Chimpanzees • Kangaroos Chimpanzee Duck billed platypus
