Again in 1878, photographer Eadweard Muybridge helped resolve a debate about how horses gallop.
Utilizing cutting-edge expertise for the time, he captured a collection of photos that confirmed they concurrently raise all 4 ft off the bottom.
It was one thing many had suspected of the sleek animal, and Muybridge’s footage provided definitive proof. Practically 150 years later, fashionable video footage has proven that hippos run in an identical method, and it is one thing nobody anticipated.
Like horses, hippos additionally get a little bit of air once they trot. There is a cut up second when the quickest animals totally go away the bottom.
Researchers from the Royal Veterinary School made the invention when viewing video footage of hippos romping round a theme park in North Yorkshire, England.
“We have been pleasantly stunned to see how hippos get airborne once they transfer shortly,” John Hutchinson, an RVC professor of evolutionary biomechanics, mentioned in a press release. “It is actually spectacular!”
Hippos transfer extra like horses than elephants

When elephants stroll, they transfer their again left leg, entrance left leg, again proper leg, then entrance proper leg, in line with The BBC. Scientists thought hippos moved in an identical method due to their monumental dimension.
Nonetheless, when Hutchinson and RVC undergraduate pupil Emily Pringle watched footage of two hippos at Flamingo Land, the theme park, they noticed one thing completely different. Whereas it solely lasted an prompt — about 0.3 seconds — all 4 of the animals’ ft did go away the bottom directly.
To confirm what they’d seen from the theme park, the researchers checked out extra movies of hippos on the web. Based mostly on the actions of 32 hippos, they concluded that their trot is much like horses.
Horses elevate all their hooves throughout their sooner strides, although not when strolling. It is an unusual gait for bigger animals akin to hippos, which might weigh over 4,000 kilos.
Realizing how the animals transfer might assist veterinarians higher diagnose hippos with mobility points, the researchers mentioned.
Why are we solely simply studying how hippos trot?
Hutchinson famous that whereas the hippos’ gliding trot is spectacular, it is not all that stunning that that is the primary time it was documented.
The animals spend most of their time within the water and will be aggressive. “That is a part of the explanation why science knew little about how hippos transfer earlier than our analysis,” Hutchinson mentioned.
The researchers printed their findings within the peer-reviewed PeerJ journal. It stays to be seen whether or not the footage of the airborne hippos turns into as iconic as Muybridge’s horse pictures.
