Why Hippos Are Not Big Five Animals (But Should Be)

Let’s address the muddy riverbank elephant in the room: hippos are not part of the Big Five.

No matter how many tourists they intimidate, boats they glare at, or guides they keep awake at night, the hippopotamus was snubbed. And frankly, it’s time we talked about it.

The Big Five — lion, leopard, elephant, buffalo, and rhino — were so-named by big-game hunters because they were the five most dangerous animals to hunt on foot. Hippos, meanwhile, were probably too busy capsizing boats and casually murdering crocodiles to attend the meeting.

So while hippos didn’t make the historical cut, they absolutely deserve honorary membership. Here’s why.

First Things First: Why Hippos Aren’t Big Five Animals

Hippos were excluded for one simple reason: the Big Five label is not about size or danger — it is about how difficult and dangerous an animal was to hunt on foot. Lion, leopard, elephant, buffalo and rhino earned their place because they were considered the most challenging and dangerous animals for hunters to track and shoot.

Hippos, by contrast, were usually found in predictable places such as rivers, lakes and waterholes, making them easier to locate. They were often shot from boats or at the water’s edge, which did not fit the colonial hunting idea of a “true” Big Five animal.

Ironically, this means one of Africa’s most dangerous animals to humans never made the list. Awkward.

How Hippos Compare to the Big Five

Animal Part of the Big Five? Danger to Humans
Hippo No Responsible for more human fatalities in Africa than any other large animal
Buffalo Yes Often considered the most dangerous Big Five animal
Lion Yes Dangerous, but usually less deadly than hippos
Leopard Yes Dangerous and unpredictable, especially on foot
Rhino Yes Dangerous when surprised or threatened

And because hippos deserve a little more recognition, here are a few surprising facts about Africa’s most misunderstood heavyweight.

Hippopotamus Amphibius Facts

The name hippopotamus (hippo for short) comes from the Ancient Greek term for "river horse": 

  • 'hippos' meaning "horse."
  • 'potamos' meaning "river"

Of the two species in the family Hippopotamidae:

  • Hippopotamus amphibius, also known as the common hippopotamus, Nile hippopotamus or river hippopotamus, is the largest. Found in Sub-Saharan Africa.
  • The other species is the pygmy hippopotamus (Choeropsis liberiensis or Hexaprotodon liberiensis). Found in West Africa.

10 Fun (and Slightly Terrifying) Hippo Facts

1. Hippos Kill More People Than Lions

Despite their voluptuous 'Michelin Man' like appearance, hippos are considered one of Africa’s deadliest mammals, responsible for hundreds of human fatalities each year. Lions? Amateurs by comparison.

Cute:  ❌
Deadly: ✅

2. They Can Run Faster Than You

On land, a hippo can reach speeds of up to 30 km/h (19 mph) — faster than the average human sprint. So no, “just run” is not a valid escape plan.

Pro tip: If a hippo is chasing you, you’ve already made several poor life choices.

3. Hippos Don’t Actually Swim

Surprise! Hippos are too dense to swim. Instead, they walk or bounce along the riverbed, pushing off with their feet and holding their breath for up to five minutes.

Graceful? No, but in a way, yes!
Effective? Terrifyingly yes.

Judge for yourself in this beautiful footage from BBC Earth: Welcome to the Okavango River, the largest inland delta in the world, where hippo pods thrive. 

4. Their Mouths Open to 180 Degrees

A hippo’s yawn is not cute — it’s a threat display. Their jaws open almost half a meter wide, armed with blunt, chunky tusks that can grow over 50 cm (20 inches).

That’s not a smile. That’s a warning.

5. Hippos Are Basically Walking Tanks

Weighing up to 1,500 kg (3,300 lbs), hippos have incredibly thick skin — up to 6 cm in places. Bullets, teeth, and bad attitudes bounce right off (figuratively… mostly).

If tanks had personalities, they’d be hippos.

6. They’re Secretly Nightlife Enthusiasts

By day, hippos lounge in water, looking like floating boulders. By night, they emerge to graze, travelling up to 40 kilometres in search of grass.

Yes, this is what makes hippos my spirit animal – lounge around all day, eat all night!

7. Hippos Produce Their Own Sunscreen

Hippos sweat a reddish, oily substance often mistaken for blood. It’s actually a natural sunscreen and antibacterial lotion.

Imagine being so unbothered by life that your body invents skincare products for you.

8. They Are Shockingly Territorial

Hippos may seem relaxed, but they are extremely aggressive, especially in water. Boats, canoes, and unsuspecting tourists are often treated as personal insults. Be sure to follow the instructions of your expert guide when you are around them.

Hippo logic: This river is mine. So is that boat. And possibly you.

9. Crocodiles Are Afraid of Them

Yes — crocodiles, those ancient killing machines, tend to give hippos a wide berth. Even apex predators know when not to start something.

Respect is earned. Fear is enforced.

10. Hippos Would Absolutely Terrify Big Five Hunters

If the Big Five were redefined today as the most dangerous animals to encounter on foot, hippos would storm the list and immediately demand top billing.

Lion? Predictable.
Buffalo? Grumpy.
Hippo? Unhinged.

The Place Where Hippos Roam the Streets

Hemmed in by an estuary to the west and the Indian Ocean to the east, the little town of St Lucia, South Africa, sits squarely in what locals proudly call Hippo Land. This is the UNESCO-listed iSimangaliso Wetland Park, home to over 800 hippos — one of the largest populations in the country.

But the hippos don’t just live in the estuary — they pop into town like oversized, bad-tempered lawn inspectors. By nightfall, it’s not unusual to find these chunky giants wandering residential streets, calmly grazing on manicured lawns while humans keep a very respectful distance. The hippos are strangely unfazed by cars, headlights, and the endless camera flashes from wide-eyed visitors.

Best Places in Africa to Spot Hippopotamus

Southern and East Africa offer some of the best hippo-viewing opportunities in the world, often with sightings that are as surprising as they are unforgettable. From bustling rivers to tranquil lakes, hippo sightings are almost guaranteed — just always best admired from a safe distance.

Southern Africa

  • St Lucia Estuary in South Africa’s iSimangaliso Wetland Park is legendary, home to hundreds of hippos that lounge in the water by day and famously roam the town at night. 
  • Chobe National Park in Botswana, especially along the Chobe River, delivers classic riverbank scenes with pods of hippos grunting in the shallows, best seen on boat cruises. 
  • South Luangwa National Park in Zambia is often described as hippo heaven, with the Luangwa River supporting one of Africa’s densest hippo populations, particularly dramatic in the dry season when water levels drop.

East Africa

  • The Mara River, border between Kenya's Masai Mara and Tanzania's Serengeti, is famous not only for the great migration crossings but also for its resident hippos, which pack into deep pools and put on noisy, territorial displays. 
  • Lake Naivasha in Kenya offers unusually close encounters, with hippos visible from the shore or on gentle boat safaris
  • Uganda’s Kazinga Channel in Queen Elizabeth National Park boasts one of the highest concentrations of hippos in Africa.

So… Should Hippos Be in the Big Six?

Absolutely.

While they may not have fit the old colonial hunting criteria, hippos check every modern box:

Dangerous ✅
Massive ✅
Unpredictable ✅
Iconic African wildlife ✅

They may not be Big Five animals — but in the real world, hippos are Big Attitude, Big Teeth & Big Problems.

So, next time you’re on safari and spot a hippo yawning in the water, remember: you’re looking at one of Africa’s most misunderstood legends — excluded from the Big Five, but feared by everyone who knows better.
