Photo by timlaman | Have you ever wondered why orangutans are such great tree climbers? Their feet have long and opposable big toes. This large adult flanged male Tapanuli orangutan was photographed in the rainforest of Sumatra, Indonesia, before this new species of orangutan was discovered in 2017.
