Interesting bit near the end:

"And even though they have incredible color-changing skills — going from beige to blood-red or striped in the blink of an eye — cuttlefish are totally colorblind."

Which raises the question of how cuttlefish mimicry works - how can it imitate what it does not perceive? There must be some feedback mechanism, what signals does it use?

I found little in a quick search: "Camouflage is one of the least studied subjects in biology" ( http://reefbuilders.com/2011/06/06/cuttlefish/ ).
