Dec. 5, 2017 - Tourists in Maasai Mara National Reserve, Kenya, witnessed an unusual sight—a pride of lions attempting to take down a hippo. Lions usually hunt easier targets, and it's rare to see them attack bigger prey.

Hippos are one of the most dangerous animals in Africa, and one of the most aggressive in the world. Their powerful jaws can snap a canoe in half. The hippo reportedly escaped.
