A population of orangutans was found in an isolated area of Sumatra in 1939, but they weren’t named as a new primate species until 2017. Today, there are only around 800 Tapanuli orangutan (Pongo tapanuliensis) living in the wild.
They are smaller and have paler, thicker fur than their lowland cousins. Scientists believe these are adaptations for living at altitude. But like all the orangutans, the bond between an infant and its mother is one of the strongest and longest in the natural world.
According to co-author Dr. Marina Davila-Ross, the Tapanuli orangutans differ “genetically, morphologically as well as behaviorally from the Sumatran and Bornean orangutans” in significant ways. And from The Guardian, “The long booming calls of the Tapanuli males differ from those of the two other known species,” as well.
