Scientists have discovered that cockroaches can change directions and body orientation instantly when trying to escape predators, flipping upside down and front to back while running at full speed, without giving a damn about gravity or physics. Check this freaky video.
What's more surprising is that they will not be able to do it if you shave their legs. No sexy legs for cockroaches. The trick is also due to the scale -- according to the researchers, "small animals benefit from the advantages of enhanced manoeuvrability".
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. [PlosOne]
