4 Amazing Animals You Can Only See in Borneo

For an island as large and centrally located (at least as a part of an archipelago in the Pacific Ocean) as Borneo, it has some unique stuff going on with its wildlife. It’s the only place in the world where tigers, orangutans, rhinos, and elephants live at the same time. Beyond that, there are quite a few animals you can’t find anywhere else. Here are four of our favorites.

4. Proboscis Monkey

A proboscis should be a physical feature limited to flying insects, not fellow primates. Yet here’s the proboscis monkey, defying all animal kingdom stereotypes. To be fair to the monkey, when people called it a proboscis, they didn’t mean the monkey had a fleshy needle it would shoot into the skins of the things it wanted to eat, just that it had a longer nose than normal. In fact, it might be helpful to think of this label as a mean nickname given by middle school bullies. Just be glad those same bullies weren’t focusing on the monkey’s pot belly. Then we might be talking about the “beer gut monkey.”

3. Borneo Bay Cat

The only really concrete information anyone has on the Borneo Bay Cat is that it exists. You can eke out a good physical description, mostly because people have set up motion-sensing cameras and been lucky enough to snap a picture. They also know it’s about the size of a large house cat. But in terms of diet, reproduction, preferred habitat, family life, and lifespan, all scientists can do is take a few educated guesses. They don’t even know if the animal is nocturnal or diurnal because those cameras have gotten pictures of them at all times of the day and night. This complete dearth of information comes from the cat’s ability to blend into its environment and evade observation in the wild. It’s a tantalizing prospect for scientists. They know it exists and they know it’s a unique animal, but details sit just out of reach, often literally.
