There is nothing ordinary about the vision of a Mantis Shrimp (Neogondactylus sp.).Timeline PhotosThe human eye has been hailed as so perfect and complex, there’s no way it could have evolved. This notion is, of course, preposterous. The truth is, our eyesight isn’t all that great, especially compared to something like the mantis shrimp. Humans have four different types of photoreceptive cells (rods and three different types of cones), where the mantis shrimp has twenty. They can also move their eyes independently and use three areas of the eye at once, effectively creating trinocular vision. Their visible spectrum is extends far beyond ours, even past UV and IR light. More info: http://bit.ly/ZIfFYb Photo credit: Marshall et al., 2007
