This is one reason orangutans are such amazing climbers–long toes, and the ability to grip with their big toe. But having these great adaptations for forest life won’t do them much good if they don’t have any forest left. Tapanuli orangutans, a new species discovered in 2017, is under serious threat in the only area in which they are found, a small area of Sumatra, Indonesia.
