    Humans Empathize with Boneless Inkers

    About Danna

    Cephalopods have been rocking my world since I was in grade school. I pursued them through a BA in marine biology at the University of California...

    This is so heartwarming. A few days ago a large cephalopod washed up on the beach in Florida, and
    Beachgoers rushed to the squid's aid. It was spitting out ink and seemed weak, [Lifeguard] Gorman said. "It's used to being in places that are dark and black," he said. "To be in the sunshine on the beach was not a good spot."
    Er, not to mention that between wet and dry, cephalopods have a definite preference. Here's a video of people collecting the creature into a cooler and bringing it out to deeper water:

     

    The media are calling it a squid, but I'm not so sure. I don't seen any fins at all in that footage, so I'm thinking octopus. (Some octopuses do have fins, but some don't. All squid have fins.) But what species of octopus? I'm a bit stuck. I don't know Atlantic cephs as well as Pacific cephs (the curse of pursuing most of my higher education in one ocean) and although the general shape reminds me of a female Ocythoe, the arm webbing is all wrong.


    (I do not know why there is a cat in that image.)

    But whatever it was, I'm glad it touched the empathy centers of the people on the beach.
    "He'll probably get eaten by a shark," Gorman said. "But I'd rather have [the squid] die in the ocean where it's supposed to."

    That’s a nice story.

    Considering how much brain cephalopods have, how much has the average gastropod?  And do bivalves have anything that could be called a brain?  (I know they have sensory perceptions, particularly those scallops that swim away when the starfish comes along.)

    I went back to good old Brusca&Brusca to check my answer on this one. Basically, compared to cephalopods, the brains of all other molluscs are small. But gastropod brains are pretty well centralized, i.e. they do have a good concentration of ganglia in their heads. Bivalves are less concentrated, as I understand it, since they're not properly cephalized the way gastropods are.
