Ologies with Alie Ward
Hippopotomology (HIPPOS) with Rebecca Lewison
Dr. Rebecca Lewison
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.
