So, I was reading the half-page infographic feature “Colossal Squid Revealed” in the latest print issue of Popular Science, and, disappointingly, it was just a recitation of information I’d long known: 10-foot-long tentacles with killer hooks, check; 10-inch eyes optimized for lightless depths, check; sworn enemy the sperm whale, check; likely to rise up and annihilate humanity pretty soon; check; we are totally screwed, check.

But then I hit upon a factoid of which I’d been previously unaware:

The squid has a doughnut-shaped brain; the esophagus passes straight through the center.

That’s just superb. The infographic is online here; click through the gallery to get to the esophagus stuff.
