The Natural History of the Sloth

  1. 1. The Natural History of the Sloth By Angel Hartman Biology 101 Professor Swatski
  2. 2. Anatomy & Physiology• Fur Coat• Algae• About the size of a cat• Small eyes, snout, head, and tail• Large eyes and legs• Very long, sturdy claws  Great for climbing  Terrible for crawling
  3. 3. Anatomy & Physiology Cont.• Slow• Don’t fall often• Body temperature 75-91 degrees Fahrenheit (24-33 degrees Celsius)• Jaguar, Harpy Eagle, and humans
  4. 4. Behaviors• Mostly upside- down• Eat, sleep, mate, a nd give birth• Nocturnal• 15-20 hrs.• Once a week from trees• Solar energy
  5. 5. • Leaves• Fruit• Flowers• Twigs• Buds• Water• 1 month to digest
  6. 6.  10-12 month gestation period One baby at a time Total of one year together 20 years in wild 30 years in captivity
  7. 7. Conservation Status• Unable to survive outside the tropical rainforests• Successful creatures• Only one species endangered• Destruction of rainforests may lead to more
