In Borneo, there's an impressive eco-tourism industry where you can climb Mt. Kinabalu, view pygmy elephants in the wild, and watch the human -
like proboscis monkeys swinging from vines in the jungle as you head down the river in a small boat.
Thanks to its adaptations,
proboscis monkeys can skilfully wade through their swampy habitat and dog paddle
like a pro, says Ramesh Boonratana of Mahidol University International College in Nakhon Pathom, Thailand.
