Peacock Mantis Shrimp
Fairly large... for a shrimp, the peacock mantis shrimp is native to Indo-Pacific waters. These shrimp can strike with the force of a .22 caliber bullet. It does this by storing energy within its arm, releasing it like a spring-loaded mechanism. Not only does this creature have one heck of a punch, it also has probably the best eyes in all of nature. Thousands of small units make up the eye and each detect light separately, leading scientists to believe they can see a massive spectrum of colors.
