Here we have the most ocularly spectacular creature known to man: the mantis shrimp. Forget binocular vision, these guys have trinocular vision, where three divisions of the eye comprise its depth perception. 12 photoreceptor pigments for light and four for color filtering grant the mantis shrimp impeccable vision, with some species capable of seeing all six types of polarization of light. All these adaptations are impressive, but not all have a clearly identified evolutionary precursor. The precision required during the mantis shrimp's hunting technique could be a factor, as could be the fluorescence displayed when courting. Many mysteries are yet to be revealed regarding this visually magnificent creature.
