Scientists have discovered that, while trying to escape predators, cockroaches can change directions and body orientation instantly, flipping upside down and front to back while running at full speed, without giving a damn about gravity or physics. Check this freaky freaky video.
What's more surprising is that, if you shave their legs, they will not be able to do it. No sexy legs for cockroaches. The trick its also due to the scale—according to the researchers, "small animals benefit from the advantages of enhanced maneuverability."
Scientists have used this discovery to develop tiny robots that can do exactly the same thing.
Oh, and geckos do it too, but geckos are cute. Cockroaches are the most disgusting things on Earth. Bastards. [PlosOne]
