The country's last male Sumatran rhino, Tam, died in May, due to old age.
The Sumatran rhinos have long been considered an endangered species. The last 80 of the entire species are in Indonesia.
Sumatran rhinos are the smallest among all rhino species and are the only Asian rhinos with two horns. Their numbers have significantly dwindled between 1985 and 1995 due to the loss of their habitat and poaching. Their horns are used in traditional Asian medicine and are considered a status symbol in countries like Vietnam.
The World Wide Fund For Nature shares ways how you can help protect the last remaining Sumatran rhinos, such as not buying rhino horn products, using forest products like wood and paper certified by the Forest Stewardship Council (FSC), and spreading the word about the species.
