A recent study from the University of London’s Royal Veterinary College has made a fascinating discovery about the locomotion of hippos. Contrary to previous beliefs, these massive mammals can momentarily lift all four feet off the ground when moving at full speed on land.
The Majestic Common Hippopotamus

The common hippopotamus, known scientifically as Hippopotamus amphibius, is native to sub-Saharan Africa. As one of the largest land mammals, adult males typically weigh around 1,500 kg (3,300 pounds), while females average 1,300 kg (2,866 pounds). Despite their immense size, hippos can reach speeds of up to 30 km/hr (18.6 mph).
Debate on Hippo Locomotion
Researchers have long debated the mechanics of hippo movement. The primary question was whether hippos use a standard quadrupedal walk or a trotting gait where diagonal feet move in synchrony. This debate arose because many large animals tend to move in ways that minimize energy expenditure and maximize stability.
The Quest for Answers
To address this debate, a team led by Professor John Hutchinson and veterinary student Emily Pringle embarked on an investigative study. They aimed to determine if hippos become airborne while moving quickly, a trait observed in many mammals but rare among larger animals.
Filming at Flamingo Land Resort
The research team filmed hippos at Flamingo Land Resort and analyzed numerous online videos to gather data. They meticulously collected and analyzed 169 strides from 32 hippos, including two zoo hippos moving briskly around their paddock.
Advanced Analysis Techniques

The team utilized high-speed cameras and motion analysis software to scrutinize the hippos’ movements. This advanced technology enabled them to capture and examine the precise moments when the hippos were in motion, providing clear evidence of their gait.
Momentary Airborne Strides
The study revealed that hippos could momentarily lift all four feet off the ground while running at full speed. This surprising finding challenges previous assumptions about the limitations of large mammal locomotion and sheds new light on the hippos’ physical capabilities.
Insights from Professor John Hutchinson
Professor John Hutchinson, whose research focuses on understanding how large animals stand and move, expressed excitement about the findings. “This discovery provides valuable insights into the evolution of locomotion in large land vertebrates,” he noted. “It shows that even animals of considerable size can exhibit remarkable agility.”

Understanding how hippos move not only enhances our knowledge of these fascinating creatures but also contributes to the broader study of animal locomotion. It offers clues about the evolutionary adaptations that have enabled various species to move efficiently in their environments.
Implications for Conservation
The study’s findings have important implications for hippo conservation efforts. By understanding their movement patterns, conservationists can better design protected areas that accommodate the hippos’ natural behaviors, ensuring their well-being and survival.
Future Research Directions
The research team plans to continue their studies on hippo locomotion, exploring how different terrains and environmental factors influence their movement. They also aim to compare hippo gaits with those of other large mammals to uncover further evolutionary insights.

The groundbreaking study by the University of London’s Royal Veterinary College has revealed that hippos can indeed lift all four feet off the ground when running, challenging previous notions about large mammal locomotion. This discovery opens up new avenues for research and enhances our understanding of these magnificent creatures.
Linnea is a born and bred Swede but spends as much time as possible in Cape Town, South Africa. This is mainly due to Cape Town’s extraordinary scenery, wildlife, and atmosphere (in other words, because Cape Town is heaven on earth.) That being said, Sweden’s majestic forests forever hold a special place in her heart. Linnea spends as much time as she can close to the ocean collecting sea shells or in the park admiring puppies.
