This lioness got the surprise of her life when she disturbed a resting hippo.

Likely interested in a meal as she roamed the Maasai Mara, the lioness approached the hippo to investigate. The colossal animal gave the big cat quite a scare when it immediately turned around and began chasing after her.

The hippo grabbed the lioness by the neck and effortlessly tossed her around. Somehow, the lioness was able to free herself — narrowly escaping with her life.

Hippos are some of the most dangerous animals in Africa, killing an estimated 2,900 people every year. Their mammoth jaws are extremely strong, with teeth weighing an average of 6.5 pounds each. These gigantic animals can also run up to 30 miles per hour.
