His species, also known as the "hairy rhino," is a descendant of Ice Age woolly ancestors. The zoo said their numbers have fallen by 90% since the '80s, in part due to deforestation in Southeast Asia and poaching for their horns.Here's some footage of Harapan frolicking around:
A report published this month said that after years of searching for the Sumatran rhino in the forests of Malaysia, officials have declared that the animal has gone extinct in the Southeast Asian country.
Now, 8-year-old Harapan will go to his ancestral home to join 14-year-old Andalas, who has so far managed to sire one male offspring since arriving in Indonesia in 2007.
