      What if it isn't farts but Hippo diarrhea? Then there would be no bubbles. If it is diarrhea, this could explain why wildlife biologists are having such a hard time pinning down the source of the sound. Have you ever tried to pin down diarrhea? Let alone diarrhea underwater in a river? I expect an answer by Monday.

    The part where the hippo is baring its teeth at the rhino to try and use its intimidation factor is hilarious once you're aware of how weak a rhino's vision and intellect are.

    I grew up in a small town called Richard's Bay in South Africa, a place known for their hippos and crocodiles. It's a coastal town. However, there are lakes in which hippos reside, and they ran down to the sea.
    One time, my friend and I planned to swim across a closed area of sea, sort of like a mini-man-made bay. We knew to keep away from the lakes, which were relatively close by as we didn't have a death wish. We started to swim. About half way into our swim we heard this clicking sound under water. We both stopped and looked at eachother puzzled but we couldn't see anything around us so we just brushed it off. We continued to swim and that clicking sound persisted. We stopped again and, I shit you not, about 10 meters from us we saw that familiar hidden face just chilling out the water. Scariest moment of my life. We grow up knowing that hippos have killed more people than any other land animal and knew we were in serious trouble. In that moment, I knew that if the hippo wanted to kill us, it already would have. So my friend and I, without trying to rush, just swam to the nearest land. I have no idea how we made it out out alive but we survived. Honestly thought I was going to die that day.
    It's true what Zefrank says about their unpredictable nature. I'm sure if it was a young bull, or a mother with her pup, we wouldn't have lived to tell the tale

      I would suspect that wasn't the hypo's usual turf, so they might have been in a less "this is my space and feel like asserting dominance" mood, and more of a "what is this place and whare those weird things over there, oh they don't seem to even notice me, oh now they're leaving... alright then, back to figuring the rest of this place out" mood. Or maybe it was just luck, that is the thing about unpredictability, sometrimes you get muder tank, sometimes you get just chilling here tank.

      Holy crap. If I didn’t have an immediate heart attack from the sheer terror of that realization, I’d have still required rescuing because I’d have frozen in place, incapable of even blinking.
      I love the heck out of hippos but, If it had been me, I’d have been praying like hell that I was just seeing a great white or a tiger shark. And I’m not even religious. Wow… congrats on your survival. Whew! 😅

      I got chased by a hippo near the Limpopo river when I was young. A true come to Jesus moment and probably the fastest I've gone up a tree in my life. At 12 years old I just remembered my grandad telling me there's no way you can outrun them so get high and stay put till they get bored and go away or help arrives. Eventually the hippo just moved on but I stayed up there a good fifteen to twenty minutes and only came down when my friends were calling for me. Yes, we were unsupervised.
      I recounted this to one of the locals with a farm bordering the Limpopo and he said I probably got near a calf and momma wasn't happy about it. I'd heard the pod some way off so I never expected to run into a solitary cow and her calf 😂 My family didn't hear this story until I was well into my twenties.

    HIGHLY recommend that anyone who wants more baby hippo footage look up the journey of Fiona from the Ohio Zoo. She was born prematurely and the zoo staff basically had to forge brand new hippo care methods to keep her alive long enough to reunite with adult parents. Really cutting-edge zoo science. And she was adorable, too. They were very successful. She's a teenager now, basically, and she has a little brother.

      ZeFrank might have the mind of a horny smirking adolescent but he's still a class act. It's not always obvious but he does a lot of teaching there in between the laughs and without the scientists he wouldn't be able to do that. He never fails to credit the research and scientists he cites in his videos. Funny or not these are wildlife documentary videos every bit as much as one by David Attenborough.

    My favorite hippo fact is that they are not fat at all - their bodies are almost solid muscle, with only about 2% body fat, significantly less than even the most athletic humans. They look big and round because that's just the shape of hippo muscles, and the only reason you can't see the definition is because they have extremely thick skin (about 2-6 inches thick) covering it.

    When I was in Uganda wih my university class of Tropical ecology, we'd spend the evening looking at the river far down below and play "Hippo or croc?" Where we'd spot a figure in the water placed bets on whether it was a hippo or a crocodile and then used our binoculars or telescopic cameras and check. It was fun!

    All things considered, I think that lion at the end got off pretty frickin easy. He could've ended up with a broken spine and/or other broken bones but he didn't actually look that worse for wear after he got away. Lol. Probably had a heart attack from the whole thing though. I love how his friend didn't even keep swimming the same direction, he was just like "NOPE I'M OUT."

    Some additional information on hippo’s phylogeny:
    Not only are whales their closest living relatives, they are also more closely related to ruminants such as bovines, sheep, deer, and giraffes, than they are related to pigs.
    Also something I love is that the clade that includes both cetaceans and hippos is called Whippomorpha.

    Great video, I love learning from this account! And a quick fun fact about hippos is they also can’t swim since they only have a thin layer of fat. Underneath that is just pure muscle which is why it’s hard to kill a hippo with say a bullet! They’re mostly muscle which is scarier than if they were just mostly fat 😅
