The big cats prowling the jungles of Borneo and Sumatra had long been assumed to be the same clouded leopards that are found in mainland Asia. Genetic analysis and comparisons of fur patterns have now shown the two animals to be as distinct as the lion and the tiger, the WWF announced yesterday. Among the findings that convinced scientists was the realisation that the Bornean cat has changed the number and prominence of its spots.

The cats have now been reclassified as the Bornean clouded leopard, with the name Neofelis diardi, to distinguish them from other clouded leopards, Neofelis nebulosa. The two species, both endangered, are shown by genetic analysis to have separated 1.4 million years ago, after the animals used a land bridge, now covered by water, from mainland Asia to reach Borneo and Sumatra.

Jaguar Jaguars (Panthera onca) are the largest felid species in the New World and the only member of the genus Panthera, the roaring cats, that occurs in the Americas. They are the third largest cat species, being outsized only by lions (P. leo) and tigers (P. trigris). Although not the largest felid, jaguars have the strongest jaw in relation to head size of any of the cats, a fact that should be remembered whenever planning to capture and immobilize these animals. The body weight of jaguars is 90 - 120 kg for males and 60 - 90 kg for females, with a large variation in body size. Jaguars live in a wide variety of tropical habitats, ranging from montane forest and wet savannah to tropical rain forest and deciduous tropical forest. The largest documented jaguars occur in wet savannahs while jaguars that live in more forested regions tend to be smaller in size

Physical appearance: Jaguars are the largest cat in the western hemisphere. In comparison with the leopard, the jaguar is generally larger and much stockier, with a broad heavy head, much shorter legs and tail (a good visual description might be a leopard on steroids). The background of the jaguar's coat is a tawny-yellow, like many of the Asiatic leopards, and lightened to whitish on the throat and belly. The jaguar is marked with small isolated spots on the head and neck with dark open ring structures, rosettes,on the sides and flank that generally contain one to four dark spots inside the rings. Interestingly, the rosettes of the leopard and the jaguar are almost identical with the exception of the jaguar having spots "inside" the rosettes where the leopard has none. Along the middle of the jaguar's back, a row of black spots may merge into a solid line. According to one Indian myth, the jaguar acquired its spotted coat by daubing mud on its body with its paws.
