Masai Mara, Kenya - an amazing video footage of a gnu about to become a meal for a crocodile has been caught. But this doesn't make the video special, what makes it fascinating is when a nearby hippopotamus drove away the crocodile and saved the gnu.
As the antelope tried to escape but had a difficult time, the hippo then accompanied it on the rivers edge and even nudged at the gnu to climb up for safety.
