A Comprehensive Safari Guide to the African Hippo
One of the continent's most iconic creatures, the African hippopotamus (often simply called "hippo"), captures the imagination of many who venture on a safari.
In today's blog, we'll explore everything you need to know, uncovering this incredible mammal's secrets.

Traits of the African Hippo
Embarking on a safari holiday offers the amazing opportunity to witness some of Africa's most iconic wildlife, and among the continent's awe-inspiring giants, the African hippopotamus truly stands out. This semi-aquatic mammal, often lovingly dubbed the 'river horse,' boasts a myriad of traits uniquely adapted to its dual life in both water and on land.
Their barrel-shaped bodies are a marvel of evolution, perfectly streamlined for buoyancy in the African rivers. With eyes, ears, and nostrils strategically positioned high on their heads, hippos can submerge most of their massive forms while still watching their surroundings, making them a captivating sight for safari-goers. Moreover, their almost hairless, thick skin secretes a natural, reddish substance nicknamed "blood sweat," which offers protection from the scorching African sun and possesses antibacterial properties.
For those embarking on a safari adventure, the sight of a pod of hippos basking lazily by a waterhole or yawning in the water with their distinctive wide mouths and formidable canines on display is an unforgettable sight.
The Hippo’s Relatives
The African Hippo's lesser-known cousin, the pygmy hippopotamus, is equally enchanting. At only about a quarter of the size of the African hippo, the pygmy hippo is more solitary and forest-bound. Unlike their larger relative, pygmy hippos spend less time in the water and more time walking across the forest floor. Although they share many physical characteristics, their lifestyles and habitats differ greatly.
What do hippos eat?
Hippos are primarily herbivores, and their diet predominantly consists of grass. An adult hippo will venture out of the water during the cooler hours of the night to graze, consuming up to 40kg (or roughly 88 pounds) of grass in a single evening.
Their large, powerful jaws and sharp incisors aren't used for eating meat; they're perfectly designed to pull grass from the ground. While they occasionally munch on some fruits or aquatic plants they find near their habitats, grass is the mainstay of their diet.
Remember, despite their hefty size and sometimes aggressive demeanour, these magnificent creatures are true vegetarians of the African plains!
How fast can a hippo run?
You'd be surprised!
The hippopotamus is deceptively quick on land for such a large and seemingly lumbering creature. While they spend a significant portion of their day lounging in water, they can reach speeds of up to 30 km/h (around 19 mph) when they feel threatened. To put that into perspective, it's faster than most humans can sprint.
This speed and sheer size make them quite formidable, especially if they feel threatened. So, while on our safari, it's crucial to maintain a safe distance and respect their space. You certainly wouldn’t want to challenge them in a footrace!
Can hippos swim?
A common misconception! While hippos spend most of their lives in water and are excellent divers, they don't actually swim in the traditional sense. Instead, they sort of "walk" or "bounce" along the bottom.
Their bodies are so dense that they naturally sink, allowing them to push off the riverbed with their powerful legs, giving the appearance of swimming. They can stay submerged for about 5-6 minutes before needing to come up for air.
Are hippos dangerous?
This is one of the most important things to understand about our hefty friends.
While the hippopotamus might seem placid and docile as it wallows in water, they are, in fact, considered one of the most aggressive and unpredictable animals in Africa. A hippo's territorial nature, combined with its formidable size, powerful jaws, and sharp teeth, make it a force to be reckoned with.
They're responsible for more human fatalities in Africa every year than other large animals like lions or crocodiles. Their aggressiveness is especially pronounced when they feel their young are threatened or during confrontations between rival males. It's also not uncommon for them to capsize boats if they feel encroached upon in their habitats.
How long do hippos live?
These incredible creatures typically live between 35 to 50 years in the wild. Various factors, such as predation, disease, and territorial disputes, can influence their longevity. In captivity, with the absence of natural predators and regular medical care, hippos have been known to live a bit longer, sometimes reaching ages up to 60 years.
Older hippos in the pod often carry with them a wealth of experience, having navigated the challenges of their environment for many decades. Each scar, notch, and mark on their body tells a unique story of their survival and journey through life in the wild!
Social Organisation: Living in Pods
Dominated by a lead male, or "bull," hippo pods establish their territories along riverbanks. Younger males often remain on the outskirts, waiting for opportunities to challenge the dominant male. Females, or "cows," and their offspring make up the core of the pod. Their collective strength ensures protection from threats and a shared responsibility in rearing the young.
How do Hippo’s Communicate?
Primarily, hippos use vocalisations, with a range of grunts, roars, and honks, each carrying specific messages, from signalling their presence to alerting the pod of potential threats. A particularly eerie and memorable sound is their distinctive "wheeze-honk," a unique call echoing through the night and easily recognisable to anyone lucky enough to hear it.
Along with their vocal calls, hippos employ non-verbal cues: the wide opening of their massive jaws, for instance, isn't just a yawn—it's a display of strength and territory, a clear signal to rivals or threats. In the shimmering waters of their habitat, you might even witness them flapping their ears or flicking their tails, further methods of interaction and communication within their tight-knit pods. Observing these subtle interactions provides a deep insight into the complex social fabric of the hippo community in the wild!
Hippo Reproduction and the Bond Between Mother and Calf
Delving into the world of hippos, one of the most touching spectacles is the intimate bond between a mother and her offspring. The journey begins with courtship, where male hippos, often vocal and demonstrative, compete for the attention of females.
After a gestation period of about 8 months, a female hippo, seeking privacy, will typically isolate herself from the pod to give birth, either on land or in shallow waters. The resulting calf, a bundle of energy and curiosity, weighs between 25 to 50 kg.
From the first breath, the mother's protective instincts are paramount. She'll safeguard her calf from predators like crocodiles, lions and male hippos, which can sometimes pose a threat. In its early days, the calf will often be seen riding on its mother's back in deeper water, a delightful sight for safari-goers!
Nursing underwater, the young hippo has evolved the ability to close its nostrils and ears to nurse, an amazing aquatic adaptability. As weeks turn into months, the calf starts joining the larger pod, but always under the watchful eye of its mother. This nurturing relationship lasts for several years, showcasing the deep familial ties and intricate social structures that define the world of the African hippopotamus.
Antipredator Behaviour: Defending the Pod
Few animals dare to challenge the might of a hippo and with good reason. When threatened, their first instinct is to retreat to the water. If pursued or cornered, they won't hesitate to charge. Those large canines aren’t just for show; they can inflict grave injuries, making even lions and crocodiles think twice.
Threats to the Species
The greatest threats to hippos come from their own habitat's degradation due to human encroachment. Additionally, they are hunted for their meat and ivory-like teeth. With the combination of habitat loss and poaching, their numbers are sadly declining. Conservationists worldwide are battling to ensure their survival, emphasising their vital role in maintaining healthy African waterways.
This deeper dive into the world of the African Hippo underscores its vital significance, not only as an iconic species but also as a guardian of its ecosystem. Every characteristic, from its robust body to its complex social structure, illustrates a millennia-long adaptation to the vibrant tapestry of life in Africa.
