Hippos are semi-aquatic mammals that spend most of the day submerged in rivers and lakes to stay cool. At night, they emerge to graze on grass, sometimes travelling long distances from water sources. Despite their seemingly slow pace, hippos are highly territorial in water and can be extremely dangerous.

They live in pods that can include dozens of individuals, providing social cohesion and protection for calves. Their massive jaws and tusks are primarily used for defense and establishing dominance within the group.

Hippos influence aquatic ecosystems by shaping riverbanks and spreading nutrients through their dung, which supports fish and bird life. They are an iconic component of Africa’s waterways, offering spectacular sightings along rivers and lakes during game drives.

Serengeti National Park is home to hippos in rivers, floodplains, and oxbow lakes throughout the ecosystem. Their presence adds to the park’s rich diversity of aquatic and terrestrial wildlife.

Hippos spend much of the day submerged, surfacing periodically for air, while small groups graze along riverbanks and temporary grasslands during the evening. Watching them interact provides insight into social structures and hierarchy among bulls and females.

Visiting during the dry season often concentrates hippos in fewer water bodies, making sightings predictable and rewarding. Experienced guides can help track pods and explain their complex social behaviours to visitors.
