Hippos can't breathe underwater, because hippos are mammals, they breathe with their lungs, and they have to be in direct contact with the air before they can breathe. Hippos can dive, but they don't breathe during that time. They can only dive for 3-5 minutes because they have to come out of the water to breathe when the time is up. When a hippopotamus is in the water, it will stick its head out of the water, or just stick its nostrils out of the water. At this point, they can breathe freely.
