1. There are 3 species of orangutan
The Bornean, the Sumatran and the recently confirmed new species (as of 2017), the Tapanuli. These great apes are only found in the wild on the islands of Borneo and Sumatra.
All three orangutan species are critically endangered. It’s difficult to determine how many orangutans are left in the world, but estimates suggest that there are just over 100,000 Bornean, fewer than 14,000 Sumatran, and less than 800 Tapanuli orangutans left.
Although they might look fairly similar with their fluffy ginger fur, Bornean orangutans have darker red coats and rounder faces than their Sumatran cousins.
But they do have some similarities - adult males have a beard and moustache - and adult female Sumatran orangutans also have beards.
