Hippos defend themselves primarily through their powerful mouths and aggressive behavior. They possess large tusks that can inflict serious injuries, making them formidable creatures when threatened. Hippos often enter the water when they sense danger but can also charge at potential threats on land, showcasing their surprising speed and strength despite their bulky size.
Additionally, hippos are very territorial and protective of their young. When an intruder approaches their group, they may demonstrate aggressive displays to intimidate the threat. While their size and physical strength are their main defense mechanisms, their social nature also plays a role, as they often defend their territory as a group, increasing their chances of deterring predators or rivals.
