The kangaroo is a marsupial, once considered a hoax.
Early explorers to Australia described bizarre creatures never before seen by Europeans. They wrote of creatures with heads like deer that stood upright like men and hopped like frogs. The creatures sometimes sported two heads – one on their shoulders, and one on the stomach. Such accounts were understandably disregarded and ridiculed by fellow colleagues.
That changed in the 1770s, when a dead specimen of this odd beast was exhibited in England as a public curiosity.
Today, this creature is known as the kangaroo, a widespread marsupial endemic to Australia. Well-known for their leaping abilities and the female pouch for carrying young (explaining the "stomach head"), kangaroos are a nationally recognized icon of Australia.
