Mantis Shrimp are you from another planet?

Mantis Shrimp

Neither mantises nor shrimps at all and in fact they are marine crustaceans aliens from another planet and can grow up to 15 inches long. They can strike by rapidly unfolding and swinging their raptorial claws at the prey, at the acceleration of a .22 calibre bullet. Because they strike so rapidly, they generate cavitation bubbles between the appendage and the striking surface.The collapse of these cavitation bubbles produces measurable forces on their prey in addition to the instantaneous forces of 1,500 newtons that are caused by the impact of the appendage against the striking surface, which means that the prey is hit twice by a single strike; first by the claw and then by the collapsing cavitation bubbles that immediately follow. Even if the initial strike misses the prey, the resulting shock wave can be enough to stun or kill the prey.


   As impressive as their arms are, the eyes of a mantis shrimp are even more incredible. They are mounted on mobile stalks and can move independently of each other. Mantis shrimps can see objects with three different parts of the same eye, giving them ‘trinocular vision’ so unlike humans who perceive depth best with two eyes, these animals can do it perfectly well with either one of theirs. And that’s not all…dogs eyes only see 2 colors and humans see 3 colors. But the Mantis Shrimp can see 15 color cones. Thats 11 exotic colors that we have never seen. What other colors are there you ask? No one knows for sure but the mantis shrimp.

     Apparently light can also travel in a the shape of a helix, moving as a spiralling beam that spins either clockwise (right-handed) or anti-clockwise (left-handed). This phenomenon is called ‘circular polarisation’. Tsyr-Huei  Chiou from the University of Maryland has discovered that the mantis shrimp’s eye contains the only known cells in the animal kingdom that can detect it.

Body Armor Arms

   The club-like arm looks like an armored caterpillar, according to findings by a team of researchers at the University of California, Riverside’s Bourns College of Engineering and elsewhere published online , in a journal Science. “This club is stiff, yet it’s light-weight and tough, making it incredibly impact tolerant and interestingly, shock resistant,” Kisailus said. “That’s the holy grail for materials engineers.” Kisailus said the potential applications in structural materials are widespread because the final product could be lighter weight and more impact resistant than existing products. For example, with electric cars less weight will reduce power consumption and increase driving range. With airplanes, less weight would reduce fuel costs and better impact resistance would improve reliability and cut repair bills. But Kisailus is primarily focused on improving military body armor, which can add 30 pounds to a service member’s load. His goal is to develop a material that is one-third the weight and thickness of existing body armor.
