Wow. Every person on the planet saw one version or another of this "Octopolis" story and had to send it to me. It was the subject of a Friday Cephalopod a year ago, you know. Apparently, this is the second octopus city discovered, which is interesting -- they're exhibiting more complex social…

Pale, drifting quietly, long grasping arms, cold and anoxic…we all float down here. Yes, I'm going to go see It this evening. It won't be half as creepy as the reality of the dark deep, though.

I think it's a portrait of my mood right now.

First, a little background: When squid mate, a male transfers its sperm to a female enclosed in complex structures called spermatophores. These are accumulated in the spermatophoric sac, a storage organ inside the mantle cavity, before ejaculation through the penis. Squid that spawn in shelf waters…

If you've ever wondered what squid ink is made of, here's your answer: Generally, cephalopod ink includes melanin, enzymes related to melanin production, catecholamines, peptidoglycans, free amino acids and metals. But mostly melanin. And mucus.

The sequel is going to go a bit dark: this is a deep ocean sponge. It's dark and ominous, and it's also carnivorous, with sticky spines for capturing and killing passing animals. I think that thing has been waiting for me in a lot of my nightmares.

Time to forage.

You Californians have no excuse. Go to the coast and stop by the Monterey Bay Aquarium Research Institute and see the Vampyroteuthis. Oh, wait, that's the fake inflatable one. I don't think you'll get to dive down into the deep dark and see a real one. You might not want to.

Living a languorous life and occasionally nibbling on a jellyfish has its virtues.

We're making the planet a better place for cephalopods. It also helps that humans are busily destroying teleost populations. David Wiltshire P.S. There's a video at the link titled "8 reasons octopuses rule the oceans". Don't bother with it. It is 8 incredibly idiotic reasons that have nothing…

Trapped in a cunning prison! Oh, no, what are you doing now? Foiled again!

When I was addressing this lunacy about how God exists because minds and mathematics are supernatural, I was also thinking about a related set of questions: biologically, how are numbers represented in the brain? How did this ability evolve? I knew there was some interesting work by Ramachandran on…

I usually only have good things to say about cephalopods, but it's hard to avoid the truth here: vampire squid aren't exactly beauty queens. MBARI

I was reading this account of an encounter between three cuttlefish -- a consort male escorting a female, who is challenged by an intruder -- and the story was weirdly familiar. The intruder’s pupil dilation and arm extension began the first of three brief bouts over the course of about four…

I'm relieved my courtin' days are over, because even if I did paint my butt iridescent colors, I don't think I could twerk it up over my head.

It's been a while since I brought everyone up to date on the progress of my Ecological Development course, because I've been busy. So have the students. After our spring break I subjected them to the dreaded oral exam, which actually isn't so bad. I tried to engage them less in an adversarial role…

Did you know cephalopods may have traded evolution gains for extra smarts? I didn't either. I don't believe it, anyway. The paper is fine, though, it's just the weird spin the media has been putting on it. The actual title of the paper is Trade-off between Transcriptome Plasticity and Genome…
