The average height of a hippo is 5ft (excluding pygmy hippos), but they have been known to grow taller. They range in weight from 2 to 5 tons.
A hippo’s incisors can grow up to 20 inches long and can easily pierce another hippo’s leathery hide, let alone a human’s flesh. A hippo’s jaws have a bite force of nearly 2,000 lbs per square inch.
Hippos secrete a red, viscous substance referred to as “blood sweat.” It’s not actually blood, and it’s exact function is not known (it’s speculated to be a sun screen or an anti-bacterial agent), but hippos seem to excrete it when they are excited or agitated.
Hippos are known as one of the most aggressive animals in the world. They frequently attack humans with no provocation.
That’s 75 times more humans a year than are killed by sharks.
