Hide and Seek

I may have posted this a couple years ago but if I did it's worth another look.

From Wired...

Hanlon’s research team has discovered that cephalopods use their exceptional vision as their primary means of detecting the brightness and patterns within their surroundings, which they then quickly replicate for camouflage. But, ironically, Hanlon’s team also found that most, if not all, cephalopods are color-blind. How then do they perfectly match the color of their surroundings? He suspects that the cephalopods’ skin has some sort of color-sensing capability, but what it is and how it works remain unknown.
