The WWF is reporting the discovery of a new species of clouded leopard from Borneo. Genetic tests have shown that it is a different species to the clouded leopard from the mainland of Southeast Asia, with almost as many differences as between lions and tigers. There are about 40 genetic differences between the two species of clouded leopard, and 56 between lions and tigers.
But what's especially interesting is that apparently there's only one of them, and it's at least 100 years old:
"For over a hundred years we have been looking at this animal and never realized it was unique," said Stuart Chapman, WWF International Coordinator of the Heart of Borneo program
