Uma Thurman helped to rescue an endangered rhinoceros in Africa

The 45-year-old actress joined a team including experts from Wilderness Safaris as they brought the white rhinoceros and her calf to safety from South Africa's Timbavati Game Reserve to Botswana, where there is less chance of poaching.

Although Uma was only part of a mission to save one animal, she urged fans to do whatever they can, however small, to save the prehistoric creatures from the threat of extinction.
