This Is Terrifying! Hippo Charges At Boat [WATCH]

Did you know that even though they look cute and friendly, hippos are arguably the biggest threat (animal-wise) to those living on the continent of Africa? They are responsible for around 500+ human deaths per year!

A few more hippo fun facts, from ScienceKids.com:

The hippopotamus is generally considered the third largest land mammal (after the White rhinoceros and elephant).
The name hippopotamus means ‘river horse’ and is often shortened to hippo.
The closest relations of the hippopotamus are surprisingly cetaceans such as whales and dolphins. Scientists believe this family of animals diverged in evolution around 55 million years ago.
Although hippos might look a little chubby, they can easily outrun a human.
A male hippopotamus is called a ‘bull’. A female hippopotamus is called a ‘cow’. A baby hippo is called a ‘calf’.
Hippos typically live for around 45 years.
