  1. Vertebrate Animals

  2. Phylum Chordate Invertebrates • Dorsal Nerve Cord • Gill Slits • Tail Structures • Closed Circulatory System • Multi chambered Heart • Warm Blooded- Body Temp. remains constant. • Cold Blooded- Body Temp. changes with external conditions. Fish Amphibians Reptiles Mammals Birds

  3. Fish • Scales- reduce friction • Swim Bladder- allows for pressure change in deep waters • Fins- swim direction • External Fertilization- except sharks and rays • Salt Water- kidneys to prevent dehydration • Freshwater- Absorb water • Jawless • Cartilage • Bony

  4. Amphibians • Adapted to Water and Land • Youth- Gills, Tail, 2 Chambered Heart Adult • Powerful Legs • Lungs • Double Loop Circulation • 3 Chambered Heart • External Fertilization • Salamanders • Frogs and Toads

  5. Birds • Eggs, Beaks, Migrate • Reasons a Bird can Fly- • Feathers- reduce friction • Hollow Bones- light • Wings- reduced air pressure Perching Prey Flightless Aquatic

  6. Reptiles • Dry Scales • Carnivore/ Flexible Jaw • Egg • Cold Blooded Turtles and Tortoises Dinosaurs Alligator & Crocodile Lizard Snakes

  7. Mammals • Warm Blooded • Females produce milk • Hair/ Specialized Teeth • Developed Brains Monotreme– Egg Laying Marsupial- Pouched Placental

  8. Placental Mammal Gestation Period Gestation Period- time from fertilization to birth. • Human- 9 months • Horse- 11 months • Cat- 2 months • Dog- 2 months • Elephant- 20.5 months • Rhino- 15 months
