This orangutan was recently distinguished from two other types of orangutans native to the island of Sumatra, in Indonesia. In 2001, the Sumatran and Borneo orangutans were recognized as their own species.
This year, University of Southern California graduate student James Askew realized that Tapanuli males had calls — long and high-pitched — that sounded different than the others. After studying more behavioral patterns, habits, and physicality, a team of researchers concluded that the Tapanuli was its own species, separate from Sumatran and Borneo orangutans.
But with less than 800 great apes left in this region, Tanapulis are the rarest great ape in the world — and critically endangered.
