Nature may be the inspiration for the next generation of body armour.
Military researchers have identified one particular species, the mantis shrimp, which has a fearsome club-shaped fist. This pounds other creatures at a speed of approximately 100,000 metres a second - roughly equivalent to the velocity of a 0.22 calibre bullet.
Now, a Californian researchers hopes to construct a man-made version of this natural design that's both thinner and lighter than present day military body armour...
One of the most complex eyes in Arthropoda reign (they can litteraly have a crosshair sight of their prey thanks to a stereoscopic view)
powerful "fists" (in fact a mix of club and harpoon) able to break aquarium glasses (and perforate scuba diver suit gloves)
A litle thing not to mess with
