Common Hippopotamus
Hippopotamus amphibius
The Common Hippopotamus is a heavyweight of the African waterways, spending its days in social pods and its nights 'mowing' the savanna. These powerful semiaquatic mammals are as fascinating as they are formidable.

A group of hippos rests in the thick, brown water of a watering hole. Most of the pod remains largely submerged to stay cool, with just their heads and the tops of their backs breaking the surface. Occasional ear twitches and minor adjustments in position are visible as they lounge together in the midday sun.

A group of hippopotamuses is resting in a muddy watering hole. Most of the pod remains partially submerged to stay cool, with several individuals lifting their heads to breathe or look around. The surrounding woodland is lush and green under the bright morning sun.

A pod of hippos rests in the calm water during the early morning hours. Several oxpeckers are seen hitching a ride on the hippos' backs and heads, engaging in mutualistic grooming behavior by picking parasites off the larger animals.

A pod of Common Hippopotamuses is resting in the center of a brown, murky waterhole. They are partially submerged, with their backs and heads protruding from the water. Occasionally, an individual twitches its ears or adjusts its position, but they are mostly stationary, likely keeping cool during the heat of the day.

A pod of hippopotamuses is resting in a muddy waterhole. Several individuals are clustered together on the right side of the pool, while one remains more isolated toward the center. The animals are mostly submerged, occasionally lifting their snouts or twitching their ears above the water's surface.

Two hippopotamuses are resting partially submerged in the murky waters of a watering hole. They remain mostly still, with only the tops of their heads visible above the surface to breathe and observe their surroundings.
Geographic range
Where Does the Common Hippopotamus Live?
The Common Hippopotamus is native to the vast wetlands and river systems of sub-Saharan Africa. Their core populations are most stable in East and Southern African nations like Zambia, Tanzania, and South Africa, where large protected river basins provide sanctuary. A unique non-native population also exists in the Magdalena River of Colombia, descended from animals that escaped a private collection decades ago.

Behavior
Common Hippopotamuses are highly social, semiaquatic giants that spend their days submerged in rivers and lakes to protect their sensitive skin from the sun. Within the water, they live in loose groups called pods, which can numbering anywhere from ten to over a hundred individuals. Though they appear lethargic while lounging, they are intensely territorial in the water, especially the dominant bulls who defend their stretch of the river with aggressive displays and vocalizations.
As the sun sets, these massive mammals emerge from the water to feed, following well-trodden paths known as 'hippo runs.' Despite their bulky appearance, they are surprisingly agile and can run at speeds of up to 30 km/h (19 mph) on land. Their relationship with humans is notoriously precarious; hippos are considered one of Africa’s most dangerous animals due to their defensive nature when their path to the safety of the water is obstructed.

Camera Tips
Capturing the Common Hippo on a trail camera requires identifying 'hippo runs'—these are unmistakable, double-rutted paths formed by the animal's wide gait as it moves from water to grazing grounds. Place your camera at a height of about 3 to 4 feet (approx. 1 meter). This height ensures you capture the full body of the animal rather than just its legs, and angling the camera slightly downward helps capture their enormous heads as they sniff the ground.
Because hippos are most active on land under the cover of darkness, your camera’s night-vision capabilities are paramount. Use 'No-Glow' or 'Black' Infrared (IR) flashes. Standard white light or glowing red IR can startle these sensitive animals, potentially causing them to charge the equipment or avoid the trail entirely. Set your camera to a fast trigger speed and a high-sensitivity setting to catch them as they lumber past.
For the best results, look for 'hippo lawns'—areas where the grass is kept exceptionally short and manicured by their nocturnal grazing. Placing a camera on the edge of these clearings provides a wide field of view for video clips, which are often more impressive than still photos for showcasing their scale. Always set up your gear during the heat of the day when hippos are safely in the water, and never place a camera in a spot that traps you between a hippo and its water source.
