What Do Hippos Eat?

Hippos may not be the obligate herbivores we thought they were.

You might’ve encountered Fiona and Fritz, the adorable brother-and-sister hippos that entertain crowds down at the Cincinnati Zoo. The pair has captured hearts all over the world and even has a dedicated fanbase (yes, you read that right!) that eagerly follows their activities and updates on social media platforms like Facebook and Twitter.

 

Here’s their Facebook fan page

 

There’s no denying that Fiona and Fritz are absolutely adorable and stellar ambassadors of their species; yet, they might be selling us a false tale about hippos. Although hippos look cute and cuddly, out in the wild they’re downright bullies! Be it in the water or on the land, hippos have a fierce attitude. They chase after safari jeeps and speed boats with the same intensity and aggression.

 

They’re the second largest terrestrial mammals  on earth, and also have the unique distinction of being one of the deadliest animals in the world. For instance, a BBC article published in 2016 estimated that hippos were one of the most dangerous animals on the continent of Africa. They’re responsible for the deaths of over 500 people per year!

What do hippos eat?

What does such a dangerous animal snack on? Hint: its not what you think! Hippos are usually (we’ll get to the “usually” part in a bit) herbivores ! These majestic amphibious mammals call Africa, specifically the sub-Saharan landscape, their home. The heat of this harsh landscape forces hippos to forage for grass at night. Hippos can travel around 10 kilometers each night, looking for grass to make sure they fill their stomachs. In fact, an individual, adult hippo can eat up to 80 pounds of grass in a single night!

Although they have canines  big enough to be called tusks, they don’t grow them out to eat. The canines or tusks in hippos are primarily used to fight other hippos or to scare off other predators (or literally any animal that annoys the hippo simply by broaching their territory).

Are hippos herbivores, then?

Generally, yes. Hippos will abide by a herbivorous diet, but these animals are by no means obligate herbivores. This means that, occasionally, they will eat a bit of meat. A 2015 study shed more light on this fact. The study found that hippos would occasionally choose to feed on carcasses of animals, like wildebeest and zebras.

Conclusion

If you ever find yourself stranded on the grasslands of Africa, it’s not the lions or hyenas you should fear most, but rather, it’s the hippos! Even beyond their general temperament and territorial issues, hippos aren’t like other giant herbivores. They aren’t strict in their herbivorous diet, and if the opportunity comes up, or if resources run scarce, they can change to an omnivores  lifestyle for a bit.

 

If there’s one thing that will save you, in the unlikeliest and unluckiest of circumstances of coming across an angry hippo, it’s that hippos are notoriously picky eaters. They prefer eating soft and tender shoots and leaves. Generally, in their natural habitat, they’d find these types of plants growing along the banks of rivers and lakes.
