Behind blue eyes

They’re dangerous, are among the most badass and intriguing undersea creatures and, according to a new study, have another unique trick that only adds to their reputation: rolling their eyes to see clearer.

Researchers at the University of Bristol’s School of Biological Sciences found that mantis shrimp use those eye rotations to enhance their polarization vision. They therefore can see the world around them with their already enhanced vision.

You see, mantis shrimp see differently than humans. While we have three different color channels (red, green, and blue) that we see through, mantis shrimp have 12. They can also see the polarization of light. By rolling their eyes, they’re not trying to sass you, but rather improve the polarization contrast of objects in their marine environment.
