When threatened, a hippo will typically charge at its attacker with its mouth wide open. This display is usually enough to scare off predators. However, if the predator persists, the hippo will not hesitate to attack. Hippos have been known to kill lions, crocodiles, and even other hippos.
In addition to their size and strength, hippos also have a number of other defensive adaptations. These include:
* A keen sense of hearing and smell, which allows them to detect predators from a long distance away.
* The ability to move quickly in the water, where they are most agile.
* A territorial nature, which means they are always ready to defend their territory from intruders.
Hippos are one of the most dangerous animals in Africa. Their size, strength, and aggression make them a formidable opponent for any predator.
