How To Tell An Octopus From A Dolphin
The porpoise may well be our last, only hope. The octopus, by contrast, may well be our greatest enemy. It is critical do distinguish between these two—one savior, the other archnemesis; one shining day, the other blackest night; one yang, the other yin, except in this case there’s no yang in the yin and no yin in the yang.
The Octopus: Master of Disguise
It’s a well-known fact that an octopus can camouflage itself so that it looks like rocks, or other underwater features of the landscape. “The secret behind their color capability is special skin cells called chromatophores. Each chromatophore consists of three bags of pigment. By squeezing or expanding the bags, octopuses can change the color displayed by each cell, allowing millions of subtle combinations.”
So if you thought that they’re always the same color, then you obviously don’t know the first thing about octopuses.
