March 15, 2007—It turns out a leopard really can change its spots—or at least its species. New DNA tests show that Borneo's top predator is one of a kind.
The differences aren't all in the genes, either—the two species have different fur patterns and skin coloration.
Weighing in at about 50 pounds (23 kilograms), the Bornean clouded leopard—as it's being called—is the largest predator on Borneo and is second only to the Sumatran tiger on Sumatra. A hunter of lizards, monkeys, and small deer, the big cat has proportionately the longest canine teeth of any cat.
Many of the estimated 8,000 to 18,000 Bornean clouded leopards in existence inhabit a Kansas-size, mountainous rain forest called the Heart of Borneo.
