Springtails that perform backflips are the quickest spinning creatures ever discovered.

High-speed cameras have clearly captured the springtails spinning in the air faster than any other animal ever recorded.

Springtails are a type of arthropod, a group related to insects, that are a few millimeters long and can be found in most places on Earth.

As its name suggests, the animal leaps off the ground using a tail-like appendage called a “furka” that folds up under its body and can instantly unfold to launch the creature into the air and escape predators.

Adrian Smith A North Carolina State University student was sifting through leaves in his backyard when he came across a round, mottled orange-and-brown reptile. Dikiltmina Minuta.

“We brought them into the lab to film them, and we were amazed by what they did,” Smith says.

Working together Jacob Harrison Smith, of the Georgia Institute of Technology in Atlanta, used a high-speed camera to capture dozens of Springtail shells, and to encourage the arthropods to turn over, the researchers placed the Springtails under bright lights and sometimes poked them with tiny paintbrushes.

With each jump, the tiny acrobatic creatures arc backwards up to 80 times their body length, and springtails can spin up to 368 times a second, faster than any animal yet studied.

Smith and Harrison found that springtails have two ways of landing: by bouncing and rolling uncontrollably, or by a fixed stop made possible by organs called colophores, sticky tubes that allow them to attach to the ground.

Scientists continue to study the jumping mechanics of springtails for engineering clues, and they are also studying the forward somersaults of the blue-green algae, another arthropod that has evolved a rapid escape jump.

Smith says people may think that everything in the natural world is explained and known, but that's not the case: “There's so much that exists within us and between us that is incredible.”

The 10 Quickest Jets of 2024: The Fastest in the World

Before the movie Top Gun, kids dreamed of being astronauts or sports stars. But after the release of the film, everyone wanted to be pilots in high-tech fighter jets.

Our gallery provides information about the 10 fastest jet planes in the world and their history.

Strap in and get your sick bags ready as we take to the skies to see which jet is the fastest.

The F-22 Raptor is a single-seat stealth fighter with a top speed of Mach 2.25 and long-range cruise capability. Its stealth capabilities are so advanced that it’s not allowed to be sold outside the United States. Despite its speed and stealth, it has been overshadowed by the F-35 Lightning II jet. Only 187 were built, making it rare to see in the air.
