On this episode of Freaky Fauna Friday we take a relaxing dive underwater to visit the hardest punching animal in the world, the Mantis Shrimp. These little guys can literally boil water with their deadly blows and implode the space around them. They also have the best eyes in all of the animal kingdom, able to see in many different light spectrums. We're even attempting to use these special qualities to detect cancer cells in human beings. So get your swimming trunks and your boxing gloves out on this episode of Freaky Fauna Friday!
