Attack of the hippo


            3. Bite



            The pressure of a bite relies on both
            the force exerted by the animal’s
            jaws and the surface area of the
            tooth. Hippo teeth have a small
            surface area, meaning that all the
            pressure from the clamping jaws is
            concentrated in just a few patches.
            This is what makes a hippo bite so
            dangerous. A female hippo’s bite
            delivers 130 kilograms of downward
            force per square centimetre (1,820
            pounds per square inch), while
            males are too aggressive to test.
              However, hippos share their
            territory with the strongest biters on
            the planet. Crocodiles can subject
            their prey to forces of 260 kilograms
            per square centimetre (3,700
            pounds per square inch), roughly
            twice as much power as a hippo.
            These two terrific enemies face
            one another on a daily basis, and
            while hippos can sometimes defend
            against the giant reptiles, crocodiles
            get the last word as they often
            scavenge from hippo carcasses.
