The Javan rhinoceros subspecies has been confirmed as extinct in Vietnam, according to the World Wildlife Fund.
Cat Tien National Park has had no sightings, footprints or dung from rhinos since the last known animal living there was found dead last April, shot through the leg with its horn chopped off by poachers.
Only 40 to 60 Javan rhinos now remain in Ujung Kulon National Park in Indonesia. They are the last known living members of the species, with none in captivity.
