Caught In The Act: Butterfly Mate Preference Shows How 1 Species Becomes 2

Biologists say they have found a population of tropical butterflies that may be on its way to a split into two distinct species. The cause of this particular break-up? A shift in wing color and mate preference. In a paper published this week in the journal ...

The Squid and the Whale: New Disney Flick?

I live in an academic bubble into which very little pop culture penetrates. I guess a few years ago there was a movie called The Squid and the Whale? I have just learned of its existence. Disappointingly, it features no marine animals or underwater scenes ...

Deep-Sea Squid Ink Themselves For Unknown Reasons

My friend and colleague Stephalopod published this cool paper a couple of years ago about how deep-sea squids use their ink. The fun fact from this paper that I trot out most often in social situations is a weird behavior called "mantle fills." ...

Squid Fronts And Backs, Ups And Downs

One of my favorite zoologist habits is to gesture on one's own body when describing an animal's anatomy. The weirder the animal, the funnier the implicit analogy. "These worms have a ventral nerve cord," I explain, drawing a line from m ...

This is a spider. This is a spider on drugs. Any questions?

It doesn't get much better than strung-out spiders and a white dude using ghetto slang. And Canada. Two caveats: one, you may want to watch this out of hearing from impressionable young children. It's not terrible but the occasional joke may be b ...

More Ridiculous Squid Reporting

The Monterey Herald hit close to home today with Turning the tables on giant, predatory squid: These fascinatingly grotesque creatures can reach 7 feet in length and weigh in excess of 100 pounds, are known cannibals and can tear off a fisherman's han ...

Visit from the Alaskan Octopus Contingent!

What is the Most Useless Cephalopod Trivium?

Possibly I have found it: Species of Opisthoteuthis are the most compressed, in the anterior-posterior axis, of any cephalopod. Mmmm! Syrup, anyone? ...

Common Names For Uncommon Octopods

Some discussion over the identity of Nemo's little octopus friend Pearl has led me into a deep investigation of Grimpoteuthis (dumbo octopuses) and Opisthoteuthis (flapjack octopuses). Both are shortened on the antero-posteral axis (which, yes, takes ...

Cephalopods Are Coming Out of the Woodwork (Figuratively)

First the bad news: our octopus died. Climbed out over the astroturf, was found on the floor the next day. Very, very sad. But, the consolation: on the same day, a dozen or so live market squid appeared in our lab, fresh from the spawning grounds, ready to ...
