The lions can face a lot of dangers. In the natural environment, all species will interact with each other. Carnivores actively attack and hunt other animals that may be herbivores or other carnivores. And the prey in the war will also fight hard for life.
Prey can not always be easily defeated nor killed in many battles. The prey when faced with danger, they will become an extremely ferocious animal, they can fight so strongly that it makes a strong and brutal species like a lion abstain.
Lions will often find themselves prey larger than their size because that prey will not be eaten by themselves, but with a whole group of lions sharing that amount of food. So lions often face great danger when they have to take down that animal, especially when alone.
The buffalo when confronted with a lion, it turns from fear to ferocity. Not only did it not run away, but it also rushed straight into the lion’s direction, even before the lion had time to react, the buffalo’s sharp horns pierced the abdomen, causing the lion to fall in pain.
