Borneo, a giant, rugged island in Southeast Asia’s Malay Archipelago, is shared by the Malaysian states of Sabah and Sarawak, Indonesian Kalimantan and the tiny nation of Brunei. It’s known for its beaches and ancient, biodiverse rainforest, home to wildlife including orangutans and clouded leopards. 

Without a doubt, the most illustrious creature that roams the legendary jungles of Kalimantan is the Orangutan. Regarded as one of the most intelligent primates, these gentle beasts use a variety of sophisticated tools and have been extensively studied for their learning abilities. Unlike their Sumatran counterpart, Borneo’s Orangutans are relatively larger and have rounder faces, while the male adults develop wide cheek fanges as they grow older.
