At Haller Park in Mombasa, two of our most iconic residents are Sally and Potty, a pair of friendly yet powerful hippopotamuses. Every afternoon, visitors gather to watch them emerge from their pond for their much-anticipated feeding time. These semi-aquatic giants are a highlight for wildlife enthusiasts, photographers, and families alike.
The common hippopotamus (Hippopotamus amphibius) is Africa’s third-largest land mammal, weighing between 1,500–3,200 kg. Despite their stocky build, hippos are surprisingly agile in water, using their webbed feet to navigate rivers and lakes.
At Haller Park, Sally and Potty have a spacious pond and shaded resting areas that mimic their natural environment. They spend most of the day submerged to keep cool, surfacing only to breathe, eat, or interact with their keepers.
Hippo feeding is one of Haller Park’s most entertaining experiences. Visitors can watch from a secure platform as staff offer large bundles of greens and vegetables.
Daily Hippo Feeding Time:
As they open their enormous mouths, you’ll notice their impressive tusk-like teeth, which can be up to 50cm long.
Sally and Potty aren’t just a visitor attraction — they’re part of our integrated ecosystem. Their waste helps fertilize our aquaculture ponds, boosting algae growth that feeds fish such as tilapia. This closed-loop system reduces waste, supports biodiversity, and educates visitors about sustainable living.
