The animal
The hippopotamus, or hippo for short, is a large, mostly herbivorous mammal native to sub-Saharan Africa. Known for its barrel-shaped torso, enormous mouth and teeth, nearly hairless body, and tremendous size, the hippo is the third-largest land mammal by weight (after the elephant and rhinoceros). Despite its stocky shape and short legs, it can easily outrun a human on land over short distances and is one of the most aggressive creatures in the world. Here’s a closer look at this fascinating animal.
Body Size and Weight
Body Size: Hippos typically measure 2.7 to 5 meters (8.9 to 16.4 feet) long and stand around 1.5 meters (5 feet) tall at the shoulder.
Weight: They weigh between 1,500 to 3,200 kg (3,300 to 7,050 lbs), with males being significantly larger than females.
Diet
Hippos are primarily herbivores, feeding on grasses. They graze at dusk and can consume up to 35 kg (77 lbs) of grass each night. Despite their large size and aquatic lifestyle, they do not eat significant amounts of aquatic plants.
Life Span
Hippos typically live for about 40 to 50 years in the wild, though they can live longer in captivity.
Native Habitat
Hippos are found in rivers, lakes, and mangrove swamps, where they spend most of the day submerged to keep their massive bodies cool under the hot African sun. They emerge at dusk to graze on grasses.
Mating and Finding a Partner
Hippos mate and give birth in water. Males (bulls) are highly territorial in water but not on land. A single dominant bull presides over a stretch of river and has exclusive mating rights with the females (cows) in that territory.
Other Facts
Water Adaptations: Hippos secrete a natural sunscreen substance that is red-colored. This secretion is sometimes referred to as “blood sweat,” although it is neither blood nor sweat. This substance provides protection against germs and sunburn.
Aggression: Hippos are considered one of the most aggressive animals in the world, posing a significant danger to humans and other animals that encroach on their territory.
Speed: Despite their bulk, hippos and are quick in water and can run on land at speeds of up to 30 km/h (19 mph) over short distances.
Jaw and Teeth: A hippo’s mouth can open nearly 180 degrees, and its large canines and incisors are used for combat and defense.
Social Structure: Hippos live in groups called pods, which typically consist of around 10 to 30 individuals, including both females and their young and a few males. Larger pods can have over 100 hippos.
Communication: Hippos communicate verbally and physically, using grunts, bellows, and splashes in the water. They can even make sounds underwater, which can be heard over long distances.
The hippopotamus is an iconic species of the African wilderness, playing a crucial role in its ecosystem by maintaining waterways and dispersing seeds through its grazing. Conservation efforts are vital to ensure the survival of these magnificent creatures in the face of ongoing threats to their habitat and population.
Hippos in East Africa
Hippos, with their colossal size and semi-aquatic lifestyle, are a fascinating sight for wildlife enthusiasts visiting East Africa. Here’s what you need to know about spotting hippos in Kenya, Tanzania, Uganda, and Rwanda, including the best times and places.
Kenya
Masai Mara National Reserve is renowned for its abundant wildlife, including hippos that inhabit the Mara River. You can observe them throughout the year, with river tours offering close-up views.
Amboseli National Park also hosts hippos, particularly in the swamps fed by the underground rivers from Mount Kilimanjaro’s snowmelt, providing year-round sightings.
Tanzania
Serengeti National Park and Ngorongoro Crater offer excellent opportunities to see hippos. The Serengeti’s Retina Hippo Pool is a popular spot, where dozens of hippos gather in close proximity. The best viewing times are during the dry season, from June to October, when hippos congregate around the remaining water sources.
Selous Game Reserve is another hotspot, known for its rivers and lakes populated with hippos.
Uganda
Queen Elizabeth National Park is one of the best places in Uganda to see hippos, especially along the Kazinga Channel, which boasts one of the world’s largest concentrations of hippos. Boat trips on the channel offer excellent viewing opportunities.
Murchison Falls National Park also has a healthy hippo population along the Nile River, visible on boat safaris to the base of Murchison Falls.
Rwanda
Akagera National Park in Rwanda provides a habitat for hippos in its lakes and the Akagera River. Boat tours on Lake Ihema offer chances to see hippos up close, along with a variety of bird species.
Tips for Spotting Hippos
Boat Safaris: Many parks offer boat safaris or tours on rivers and lakes where hippos spend most of their time. This is one of the best ways to safely observe hippos up close.
Early Morning and Late Afternoon: While hippos spend much of the day in the water, they go ashore to graze in the early morning or late afternoon. These times can be good for observing their behavior on land.
Stay Safe: Always keep a safe distance from hippos, whether you’re on a boat or observing from the shore. Hippos can be very aggressive, especially if they feel threatened.
Observing hippos in their natural environment offers a unique glimpse into the dynamics of Africa’s freshwater ecosystems. Each of these countries provides a distinct backdrop for hippo sightings, contributing to a memorable safari experience.
