years ago i learned (thank you, oatmeal) about mantis shrimp and how it can perceive 12* different color channels and i am not the same person since

for comparison, we, humans, can only perceive 3 channels (red, green, blue)

what do the other 9 channels look like?

🤷‍♂️

*— it actually varies from 12 to 16

how do they know it can perceive that many color channels?
