The Ecology of Vision Labs at the University of Bristol has been able to fish out the visual aspect of the world as it appears to a cuttlefish. For a gecko, slit-shaped pupils allow for multifocal vision. A thin, mirror-like structure resting on the back of a gharial’s eye allows light incident on it to be reflected multiple times. The compound eyes of a blue crayfish sit atop stalk-like structures that jut from the head and can take in multiple views of its environment at once. Spookfish use a mirror to form an image. The ogre-faced Spider has six eyes all sheathed in an extremely light-sensitive membrane that is destroyed at daybreak and replaced by a new one at night that allows for superior night-vision. Mantis Shrimp’s eyes have 12 color receptors that allow for a refined color vision and are capable of infrared, ultraviolet and polarized light vision. Bees have a heightened sensitivity to UV. Goats have square pupils. They see the world at a 145 degrees wider angle than humans.
