  3. Animals related to the turtle • Snakes, frogs, alligators and other reptiles • All have scaly skin and are cold blooded Animals related to the turtle

  4. Habitat Habitat Desert Turtles Water Turtles • Round to hold water • Live in deserts and dry forests • Don’t have webbed feet and cannot swim • Are great at surviving a long time in heat Water Turtles Desert Turtles • Flat • Live in creeks and ponds • Have webbed feet • Swim to catch food • Sleep on rocks outside of water • Flat • Live in creeks and ponds • Have webbed feet • Swim to catch food • Sleep on rocks outside of water • Round to hold water • Live in deserts and dry forests • Don’t have webbed feet and cannot swim • Are great at surviving a long time in heat

  5. Movement Movement • Walk on all fours like mammals do • Some move slow (except red glider) • Have sharp “nails” to help catch food and defend themselves against predators • Walk on all fours like mammals do • Some species move slow, others like the red glider turtle move fast • Have sharp “nails” to help catch food and defend themselves against predators

  6. Feeding Feeding • Use tiny beak in the front of their mouths and tear food into tiny pieces so its easier to digest • What turtles eat depend on where they live • Wild turtles eat a lot of plants that grow in water and small insects • Carnivorous • Use tiny beak in the front of their mouths and tear food into tiny pieces so its easier to digest • Wild turtles eat a lot of plants that grow in water and small insects • Carnivorous

  7. What Eats Turtles? Crocodiles, Alligators, Raccoons and Big cats

  8. Circulation/Respiration Circulation/Respiration • Have lungs to breathe • If they live in water they come up every few seconds for air • During hibernation they store air in their cloaca • Have lungs to breathe • If they live in water they come up every few seconds for air • During hibernation they store air in their cloaca • Aquatic turtles breathe through their skin

  9. ReproductionReproduction Reproduction • Mating: turtles bob their heads, make noises and dance to find mates. • Egg laying: before female lays eggs it digs a hole on the beach • Hatching: babies spend month in shell feeding off yoke • Peck out using “egg tooth” • Mating: tutles bob their heads, make noises and dance to find mates in a matter of seconds. • Egg laying: before the female lays eggs it digs a hole on the beach • Continue digging until hole is big enough to protect eggs • Hatching: babies spend month in shell feeding off yoke • Peck out using “egg tooth”

  10. Nervous System Nervous System • Composed of the brain, nerves and spinal cord • Brain is the center of turtles nervous system • Spinal cord extends down turtles back and protected by carapace vertebrae • Through the spinal cord is how the brain sends signals • Composed of the brain, nerves and spinal cord • Brain is the center of turtles nervous system • Spinal cord extends down turtles back and protected by carapace vertebrae • Through the spinal cord is how the brain sends signals

  11. Interesting Facts Interesting Facts • A turtles gender is based on the temperature of the nest • Turtles are adapted swimmers • Turtles can migrate extreme distances • Turtles live a long time • Sea turtles are endangered • A turtles gender is based on the temperature of the nest • Turtles are adapted swimmers • Turtles can migrate extreme distances • Turtles live a long time • Sea turtles are endangered
