00:00I think I know the animal with the coolest eyesight.
00:03Their eyes can rotate independently in three dimensions.
00:06They can perceive distance with just one eye.
00:09And they can see way more of the electromagnetic spectrum than we can.
00:13Got a guess? It's the mantis shrimp.
00:15Look at their giant eyes!
00:17They're on the end of stalks that allow them to swivel on their own.
00:20And if you zoom in, you'll see they have thousands of individual lenses and retinas
00:24that each sample a tiny area of their field of view.
00:27And because multiple of these lenses or retina pairs can focus on the same point,
00:31they can tell how far away something is with just one eye.
00:34And while we humans have three different color-sensitive cells in our eyes
00:37that let us see these different wavelengths, mantis shrimp have 16.
00:41We don't really know what they do with all of this visual information.
00:44But one theory is they use it to communicate in a way that's undetectable by predators.
