If you’re an octopus or a cephalopod you really need to know how to understand how to use your surroundings to hide.

Look at this corral bottom, as captured by a diving photographer.

There’s some algae in the foreground. This octopus can shift its color and skin texture to remain invisible!

The animal can also shift brightness and pattern. Absolutely incredible!
