WATCH: Lion gets a left-hook to the face for trespassing in another's territory
This lion got a big lesson about snooping in fellow lions' turf.
The invader got a big left-hook from its rival, who ended up forcing him out of his space, luckily with little injury.
The video was shot in South Africa by a wildlife guide on one of his tours.
Male lions are extremely territorial, especially when one is challenged for dominance over a pride. Females however stick together, specifically with their relatives.
