The Peacock Mantis Shrimp
As beautiful as the peacock mantis shrimp is, it’s not an aquatic animal that you should really mess with. Despite how small this shrimp is, you’re better off keeping your distance. And that’s because these cool animals know how to pack a punch. How powerful are they? Their punches are capable of ripping open the hard shells of mollusks and crabs, and it’s one of the fastest movements to take place underwater, not to mention in the entire animal kingdom. Furthermore, their punches can even kill other shrimp if they feel threatened, winding back with their powerful forearms and smacking the ever-living crap out of anything nearby.
