If you had eyes like a Mantis Shrimp, what could you see? With the amount of UV rays, fine particulate matter, etc... the world might be a scary place to see. Ok, in some regards, it already is a scary place to see... but I'm talking about what your eyes would detect on a daily basis. The sensory gifts that each species posesses is extraordinary. The other evening I was sitting on my couch eating my favorite cookies... Peanut Butter Power. Yes, Peanut Butter Power is from my wife's company Bella's Cookies, but what I'm getting at is... my dog, Elvis, knew what they were too. My wife has trained them to hear the crinkle of the bag, the scent of peanut butter... and Elvis knew exactly what I had in my lap. Before I even opened the bag, he had inched his way closer to the couch, and rested his head on the armrest... staring at me with labrador eyes, ears perked forward, wagging his tail. Of course I gave him a bite! :)
Read up on the Mantis Shrimp's wonderful eyesight below... I always like this guy because his claws pack the power of a .22 rifle. Have you ever seen this guy in action? Little fish don't have a clue what hit them. POW!
