Can a Hippo Drown?
Even hippos take in the oxygen they need to live without exception through lung breathing. So, can hippos drown? Indeed, even hippos can drown if they don't regularly take air from the surface of the water.

Will hippos drown in deep water?

Most mammals are naturally buoyant, but hippos have especially dense bones to help them stay on the bottom. Seawater is about 2.5 per cent denser than fresh water, but the extra buoyancy this provides isn't enough to offset the weight of a hippo, and it will still sink in the sea.

Do hippos drown often?

Among the more interesting hippo facts is that hippos don't drown because they close their ears and nostrils while underwater. What is this? They also have a membrane that closes over their eyes underwater. Hippos have a natural built-in reflex that causes them to reach for the surface to breathe.
