The secretive clouded leopard of the Borneo rainforest are actually a new, separate species:
"Who said a leopard can never change its spots? For over a hundred years we have been looking at this animal and never realized it was unique," said Adam Tomasek, head of WWF's Borneo and Sumatra program. "The fact that Borneo's top predator is now considered a separate species further emphasizes the uniqueness of the island and the importance of conserving the Heart of Borneo."
