So, I’ve been checking out cuttlefish to find out what exactly is up with their ability to mimic any environment, by producing any set of colors imaginable on their skin with reasonable accuracy. Being able to generate active camouflage like that would be pretty incredible, right?
I learned that not only are cuttlefish really completely amazing in this regard (see wikipedia and read about chromatophores), but that cuttlefish-language is color-pattern based! AWESOME.
Additionally, cuttlefish have a W-shaped pupil — yes, a W-shaped pupil — that’s sensitive to light polarization! Try to imagine the world as you see it, plus the ability to see — and speak — polarization.
There’s no end to how cool and amazing this universe is!
