Talk about some wild mechanics: Mantis shrimp (Order Stomatopoda) can really pack a punch! Their two forelimbs can accelerate at the same velocity as a gunshot and move so fast that the water around the limbs boils (called supercativation)! As the boiling bubbles collapse they create a shockwave that can kill prey even if they miss. The mantis shrimpʼs epic punch can break through shellfish, kill fish, and break through aquariums.
