7 incredible animal myths (that eventually turned out to be true) that is rather interesting. I think it's neat how some animals from folklore have been verified to exist and how some scientific theories have been proven, all by the discoveries of new species.
I think the last paragraph of the article sums it up perfectly:
All of these animal rumors were once considered unbelievable, but they all turned out to be true. One can only speculate as to which legendary beasts of today will eventually be discovered as real.
