Sneaky cephalopods

I know, I haven't posted in a while...
Here is an awesome  TED talk about cephalopods. Specifically, cephalopods include squids, octopuses and cuttlefish as well as the nautilus and allonautilus. We have already seen a friggin' awesome cephalopod the Humboldt Squid. Here, the host of the talk, David Gallo, known best for his work mapping the ocean world with manned submersibles and robots discusses the use of cephalopod cromatophores for evading predators, intimidating competitors, and pandering to the ladies. The camouflage in these videos is incredible.
