Something that the squishies can do better than arthropods

OK, I will admit it. There is one spectacular thing cephalopods can do that mantis shrimp simply don’t have an answer for. Squids, cuttlefish, and octos are the true masters of active camouflage. Through the use of muscle-controlled chromatophores, filled with colored pigment, cephalopods can rapidly and seamlessly blend in with their surroundings or communicate with others.

Today, a lab-mate was dissecting some Longfin Inshore Squid (Loligo pealeii). The chromatophores on these animals were still physiologically active, even though they were sacrificed over a day ago and shipped to us on ice. I was able to capture some video of these beautiful chromatophores in the skin rapidly expanding and contracting. Enjoy.

There will be more video content to come. Can you say mantis shrimp plus power metal? Oh, hell yeah!

    This is amazing! I’m about to cry a lil … did I mention that I’m a huge sap/overly sentimental? (I just understand beauty better than other people??! That’s maybe giving myself too much credit)

    Sharing this with all my frienz

    Thanks for making/sharing this!

      Don’t feel too sappy, I am also pretty susceptible to getting misty-eyed over beautiful nature.

      I actually wish I had made this video a little sadder. When I was putting the video together I wanted to make it look like there was more and more activity in the chromatophores to go along with increasing complexity of the canon. Now, I wish I had gone the other way, making it look more like it was shutting down, which it unfotrunately was.

      But then again, that could have made it cross over into morbid territory, which was not my intention.

    Something squishies do better than crunchies? That was lovely. Thanks. Perhaps we may yet lure you to the winning side in the Invertebrate Wars after all. :)
