These river giants create their own sunscreen. Their skin releases a red fluid that doubles as an antibacterial shield.
Despite their huge size, they outrun humans on land, reaching up to 30 km/h in short bursts.
Calves enter the world underwater and immediately kick up to breathe, showing natural survival instincts.
Submersion helps them avoid overheating. Hours in rivers and lakes keep their bodies cool against harsh sun.
Jaws stretch nearly 150 degrees, displaying massive teeth that continue growing throughout life.
They can hear above and below water simultaneously, which makes them excellent at detecting approaching danger.
These animals vocalize with honks and grunts. Their calls travel through both air and water at once.
Although many view them as gentle, they are among Africa’s most aggressive and territorial creatures.
The hippo does not swim in a traditional way. Instead, it moves by bouncing gracefully from the riverbed.
Each individual has a recognisable grunt, allowing groups to identify members by voice alone.
Their lower tusks keep growing and can reach half a meter, making them powerful defensive tools.
With three stomach chambers, digestion becomes more efficient for fibrous plant material than in many grazers.
While sleeping, they surface automatically for air without ever waking. This reflex keeps them safe and alive.
