EXISTENCE?
  • In the 1700s, European scientists thought that
    the platypus did not exist.
  • Naturalists from Australia sent a live platypus
    to Europe to prove its existence.

5
CONSERVATION
  • Platypus was close to extinction in the 19th
    century because they were hunted for their fur.
  • Fishermen did not like them because they like to
    eat fish.
  • Now, they are protected by law.

6
HOME
  • They live in burrows that they dig underground
    near water.
  • Burrows can be up to 60 feet long.

  • There are only two animals in this group
    Platypus and Echidna.
  • They are the only mammals that lay eggs rather
    than give birth.

FUR
  • Fur is fine and dense.
  • There are two layers undercoat and long guard
    fur.
  • Together, the layers trap air in order to keep

    periods of time.
  • Water never gets through to the skin.

SWIMMING
