As we’ve mentioned before, the mantis shrimp isn’t known for its kindness. It can strike with amazing force and can even wound humans if not handled properly. Depending on the type of claws they have, mantis shrimps are either ‘spearers’ or ‘smashers’, and neither of them is very nice. The Spearers’ claws have appendages with spiked tips which they use to stab their prey, mostly worms and fish. The smashers’ claws are club-like and can be used to smash prey into pieces. With a force of over 1,500 newtons, the smasher’s punch is as swift as a bullet and can destroy crabs and clamshells. This sadistic shrimp’s force is 2.5k times more than its own weight. If humans were able to strike this hard, they could penetrate through steel with their bare hands.
The mantis shrimp is neither a shrimp nor a praying mantis. It is its own species of the order of the Stomatopoda. Still, it got its name because of its unusual look. The mantis shrimp’s eyes can move independently and have trinocular vision. These little guys can use their eyes to accurately assess depth and distance. As far as science knows, they have the most intricate ocular system in the animal kingdom. Their eye structure has been compared to the technology used in DVD players, only far superior. With such great eyesight, you’d be surprised to learn these fellows aren’t actually that great at differentiating colors. But, who needs to be able to tell red from blue when you can detect cancer cells using your eyes? Yes, researchers presume that the mantis shrimp can use their eyes to differentiate between cancerous and healthy tissues. This isn’t science fiction you guys, it’s the mantis shrimp, so beware.
