Put a cuttlefish on the spot — or, to be more exact, a series of spots — and it will disappear.
But no one is quite sure how a cuttlefish brain takes what the eyes see and gets the muscles of the skin to copy it.
Are they watching their own skin as it changes and tweaking it to fit the sand?
In an effort to answer this question, scientists have turned to high-resolution videos that can show what individual skin cells are up to as a cuttlefish changes color.
The findings are a glimpse at what’s going on in a fundamentally different form of life as it does something that, to our eyes, seems almost magical.
