What is so unique about Australias animals?
When Australia drifted far north and broke away from Gondwanaland, many of the animals got isolated from the rest of the world which were used to the colder climate adapted to the hot weather we now have. They aren’t found anywhere in the world – even a platypus’ look made other countries thought it was a hoax that it was just pieces of different animals stitched together as there are no other animals that have a bill like that and can live on both land and water.
