Clip Description

There are 5 different species of rhinoceros. The largest of these is the white rhino. It is found in Africa and can weigh up to 3,500 kilograms. The Sumatran rhino of Asia is the smallest, but it can still weigh up to 900 kilograms! All rhino species are critically endangered. This means that they could be facing extinction in the wild. The main threats to their existence are poaching and the loss of habitat.

In this fascinating clip, we meet Dr Zulfi Arsan at the Sumatran Rhino Sanctuary. Rhino sanctuaries are areas of land that provide the animals with a safe space to feed, breed and roam. They are often surrounded by a long, high perimeter fence that stops poachers from getting in and rhinos from getting out. Why does Zulfi enjoy his work so much? Watch the clip to find out.
