Why Are There So Many Unique Animals In Australia. So an exceptionally large proportion of australia's plants and animals are endemic, meaning they naturally exist nowhere else in the world. For millions of years, the australian continent was so far away from any other landmass that there was no possibility for new types of animals to get to it.
There are so many interesting animals in australia! Also australia is known for having unique animals because there are so many that cant be found anywhere else but australia. Everyone’s heard of kangaroos and koalas and knows that there’s more animals in australia that can kill you than anywhere else, but there’s a huge amount of wildlife native to australia that you’ll be amazed at.
That is why on the mainland many animals' groups have distinctive signs (marsupial mammals, for example).
Australia probably has between 200,000 and 300,000 species, about 100,000 of which have been described. Marsupials like koalas, kangaroos and many others can be found nowhere else in the world, neither can our two egg laying mammals, the platypus and the echidna. Why is australian wildlife so unique? Australia is well known for their cuddly koalas, but they are not the only adorable native animals we have.
