Nature is an unforgiving place, and sometimes even apex predators can find themselves overcome by their erstwhile prey. The video below appears to show just such a situation.
The recording beings after a lion pride has apparently taken down a giraffe calf. Several members of the group can be seen feasting on the kill. Some distance away, however, a shocking scene is unfolding: an adult giraffe is kicking an apparently dead lion. Presumably the giraffe calf belonged to the adult, who somehow managed to get a leg up on one of the attacking cats. The giraffe is later chased off by another lion.
The footage may be considered graphic by some viewers.
