The thickness of the skin and bulky size of hippos make hippos almost bulletproof or immune to bullets. However, one can bring a hippo down by shooting him in his torso – the skin is fragile in this area.

Can a hippo survive a gunshot?

Hippos are known to survive entire shells of machine gunfire. It almost takes six rounds to get them on the ground. They can survive against regular bullets with any part of their body that isn't connected for mating and seeing. But if the bullets are larger than regular ones, hippopotami can't survive.

What animal is bulletproof?

Armadillo

Since the shell is composed of lots of small osteoderms, the skin is still flexible. The armadillo can roll itself into a protective ball. Urban legends say that armadillos are bulletproof because people have “seen” bullets ricocheting off the balled-up animals.
