A little reason to celebrate

World Hippo Day

Animal ยท February 15

A day about the hippopotamus, the huge, river-dwelling African mammal, marked in the United States too with zoo visits, reading and documentaries.

World Hippo Day

World Hippo Day falls on Monday, February 15, 2027. That is 111 days away.

The hippopotamus is one of Africa's largest land animals, a barrel-shaped plant eater that spends its days in rivers and lakes and comes ashore at night to graze. This day, also called National Hippo Day, is marked in the United States too, mostly by people who find the animal hard to stop looking at.

Up close, a hippo is a study in contradictions. It looks slow and round, yet it is powerful and can be dangerous to people who get too near. It cannot really swim the way a fish or a seal does. Instead it walks or bounces along the bottom of shallow water, with its eyes, ears and nostrils set high on its head so it can stay mostly hidden. Its skin is sensitive to the sun, which is one reason it keeps wet through the heat of the day.

The name comes from Greek and means something like river horse, though its closest living relatives are actually whales and dolphins. That family tree surprises most people the first time they hear it.

Most people mark the day from a respectful distance. Zoos often share news about their hippos, and nature documentaries show the animals in groups, crowded together in the water and grunting at one another. Children's books have long treated hippos kindly, so a library shelf is a fine place to start.

Watch one for a while and you notice how much of its life happens with just the top of its head above the surface.
