Guess what this is:
Give up? It’s the skin of a deep sea squid, photographed by Australian researchers earlier this year. When I first saw this picture, I was taken aback at how beautiful it is, how it looks like some exquisite, hand-made fabric. And, come to find out, the squid’s skin is like that for a reason. As this nifty article points out, squid have the ability to change color to camouflage themselves from their enemies, and how it all works is pretty nifty. In fact, this article notes that squid might be able to send each other secret messages using this system which would be invisible to the naked eye. Cool!
