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, Santa Barbara, followed by a PhD dissertation at... Read More »

Squids, as I may have mentioned before, are the snacks of the sea. Everyone who can eat them, does. Whales. Sharks. Birds. Other squids. They're swimming tubes of protein with no scales or bones to get in the way, and they're highly abundant. If you're any kind of marine predator, squids are the perfect prey.

But one has to wonder: if squids fuel everything from albacore to albatross, what fuels the squids? Sure, they'll eat each other, but the ouroboros model doesn't really work that well for ecology.


I thought I'd write a compelling story about Humboldt squid and one of their favorite prey items, the lightfish Vinciguerria. These two creatures are quite the dynamic duo: one flashing like a red-and-white strobe, the other studded with glowing photophores. They clearly belong at some kind of deep-sea rave.

But I'm riding a train, and I keep getting distracted by the scenery. I can't help it; I love the California hills!

By the fifth false start, I realized that if I wanted to post anything today, it would have to be light and fluffy. So here is a picture I took of a juvenile Humboldt squid in an aquarium:


No, I'm not suggesting that when a recession hits, you should go out and invest in squid fisheries. (But I'm not not saying that. I'm--oh, forget it.) Rather, in the words of my PhD advisor William Gilly:
Making good from bad is something that we need to learn more about, and perhaps economics theorists can learn from the strategies of the Humboldt squid.
In his latest blog post at Scientific American, Gilly tells a very curious story about how Humboldt squid in the Gulf of California responded to an "ecological recession," and how they're recovering. 
The famous Northwest Passage has become infamous in recent years, as Arctic sea ice coverage shrinks and leaves an open waterway between the Atlantic and the Pacific Oceans. We tend to think of this in terms of what it means for human transport and drilling, but we're hardly the only fish in the sea. Are there any other species taking advantage of the chance to explore?

Reuters article by Michael Ricciardi says Yes:
Is it possible to bring up a squid-related topic about which I have nothing to say? So far, the answer seems to be no.

I'm not sure if I should be proud--or find some more hobbies.

Anyhoo, today's blog-babble is tipped off by odori-don, the dancing squid rice bowl. (That linked article includes a video, for the morbidly curious.)
A couple of curious squid stories have been peppering my news feed this weekend:
First, a dried squid in Hawaii looked enough like a severed hand to get the homicide brigade called out to the beach.

Um, creepy! And not particularly squid-like. I think I agree with the commenter who suggested it might actually be a dried octopus.
