Tasmanian Tigers Are Extinct. But are they? Can you prove "There are no Tasmanian Tigers alive"? It's very hard to prove a negative. Just like the old saying "There are no such things as black swans." was rendered completely false by the discovery of a few black swans in Western Australia two hundred years or so ago. Today we know that thousands of black swans exist quite happily. Personally speaking, I don't believe there are any more Tasmanian Tigers left. However, there is still a lot of wilderness on the west coast of Tasmania, and it is possible that some still survive there.
