A school of hippos gives an aggressive warning sign | Primal Survivor: Extreme African Safari

(Exhales forcefully) But it's not crocodiles I should have been watching out for. Instead, it's one of the most temperamental animals out here. (Hippo snorting) Wow, there are a lot of eyes looking in my direction, a lot of ears pointed in my direction. They know I'm here.

Hippos kill more people than any other large animal in the entire world. Being so packed together in such limited water, they're stressed and ready to defend their territory. Ooh, ooh, ooh. Look at that one. It's starting to come up, it's starting to come up.

-(Hippo bellows) -Oh, oh, oh. Just showing me their jaws, showing me their tusks that could literally cut a man in half. (Hippos grunting) They're telling me to back off.

Hippos are dangerous in and out of the water. They can run up to 22 miles an hour. And in this area, I need to keep a lookout everywhere around me. Oh, oh, oh, oh. Here's what I'm talking about. The ones that are up on land, those are just on the land feeding, which means there could be more out here. That's when they get really dangerous.

Okay, time to go.
