And it's a bummer for them because those canine teeth actually do have ivory. Oh. So it's not as high quality as elephants, but it's one of the reasons that hippos have gotten wrapped up in the ivory trade. or legal ivory trade is because they're canines. So those are the ones that are sort of the curved ones coming out of their bottom jaw have Ivory, made of ivory, yeah.

All right. You ready? They aren't even swimming. No. They can't swim. They sort of glide, walk, run along the bottom. So they're never in deep water? They can be in deep water. They can be submerged. They can stay under for about five to six minutes, but they're not actually swimming. I guess if you think about like if you were doing aqua aerobics.

I was just going to say, this is like going to the Y. What? Yeah. Don't try this with them, but it is just like that.

Yeah, that's a really good question. What are they doing under there? So one thing, remember we talked about them being related to whales. They have nostrils on the top of their... So if you look at a hippo, let's see, how do I describe this?

And they actually have muscular and anatomical features that are similar to blowholes. So the nostrils close when they go underwater. And when they come up, one of the ways you know that there's a hippo there is because you hear the right, when they blow out. And so that's similar to what we see with cetaceans, right, when they come up and they're blowholes.

So there's actually some characteristics of their nostrils that are similar to that. What do they do underwater? It's hard to know because we really, it's very hard to see. Jacques Cousteau famously like put this fake hippo and people have tried this, like deploy like a autonomous, you know, vehicle in the water dressed up as a hippo.

It doesn't go very well for the daughter of the vehicle, right? The hippos are just like, no, get that thing out of here. So it's pretty hard to see what they're doing. And mostly they're in water that is not clear. You can't see anything.
