30. Peacock mantis shrimps throw the fastest punch

The peacock mantis shrimp, a relative of crabs and lobsters, throws a punch at 50 mph, which is faster than a .22 caliber bullet. It uses its punch to impale soft-bodied prey like fish. And since it lives in overcrowded and competitive rock crevices, researchers believe it developed this strength to out-maneuver other hunters.
