The best known animals in Tanjung Puting are the orangutans, made famous through the long-term efforts of the Orangutan Research and Conservation Program.
Tanjung Puting also boasts the bizarre looking proboscis monkey with its “Jimmy Durante” nose as well as seven other primate species. Clouded leopards, civets, and Malaysian sun bears cavort in the park, as do mouse deer, barking deer, sambar deer, and the wild cattle known as banteng. Tanjung Puting hosts over 230 species of birds, including hornbills, deep forest birds, and many wetland species. Tanjung Puting is well known for its “bird lakes,” seasonal rookeries for a half a dozen species of endangered waterbirds, including the only known Bornean nesting grounds for white egrets. Tanjung Puting also has two species of crocodiles, dozens of snakes and frogs, numerous threatened species, including the fortune-bringing and highly endangered “dragon” fish also known as the Arwana (bony-tongue). Among the most flamboyant of these animals are the many species of colorful birds, butterflies, and moths found in the Park.
