1 The saiga antelope has long, thin legs and a big, long nose which hangs over its mouth. It's the same size as a sheep. It has light brown fur in summer, then thick and white in winter.

2 They live in groups (herds) of 30 to 40 animals.

3 In 1990s there were up over a million saiga antelopes, but today they are thought to be around 50 000.

4 The saiga has been hunted for its meat and horns. It has also lost its habitat.

5 Many organisations are working hard to protect the saiga, and to stop the sale of its horns for Chinese medicine.
