Cuttlefish: master of disguise

Every one of my European friends speaks at least two languages, if not three or four. But I bet none of them speak color.

That’s the language of cuttlefish, which communicate in shifting waves, spots and splashes of color. The speed of their changes is almost beyond the comprehension of us clumsy humans, who must push our tongues around our mouths to make language.

In addition to communication, cuttlefish use their color shifts as well as changes in skin texture and body posture to blend in perfectly with their surroundings. They can be a bit of algae moving in the current, a nudibranch crawling over the sea bed, a sponge, and any number of other disguises. Watch this video (full screen if you can), and be amazed:
