Mantis shrimp (which are actually crabs, not even shrimp) are the Mike Tysons of the ocean world. Equipped with the best visual system and strongest pound for pound punch of ANY creature, they are so troublesome that most aquariums do not hold them, as they would shatter their glass box. Its punch is so strong it creates light and heat as well as a cavitation bubble (a bubble that is made when an impact rips water apart, creating a shockwave). The punch is equivalent to a .22 bullet's velocity upon leaving the barrel. Mantis shrimp have more rods and cones in their eyes and can see more colors than we can. Imagine 13 colors you can't see, plus the ones you already can. That's what a Mantis Shrimp can see.
