Very interesting, but which one is wearing the G string?

Why do I get this image in my head of two C'thulus kissing?

Thanks, PZ! I get to put porn on my desktop at work without getting into trouble.

Presumably a NaughtyLass and a NaughtyLad - unless PZ knows more about the incidences of (intended or accidental) homosexuality among cephalopods.Posted by: K. Signal Eingang | February 16, 2007 11:21 AM

OH MY! How dare you put such a graphic and lurid picture on the internet? What's next?! You're going down a slippery slope!

Invertebrate ventral mating? Who woulda thunk? Wish I could've had this graphic last week! But I did find movies of the nautilus, BTW, and ran them during my Darwin Day Power Point. At my church, while showing some kids some ammonites, most fun I've had in weeks. As always, PZ, your site is an invaluable resource.....SH

Yeah, but they can't look each other in the eye.

Accidental homosexuality? Would that be similar to Rev. Haggard?

I was thinking more in terms of the squid orgies in which tentacles and sperm packets go every which way.

It's so heartwarming in some very strange way.

Awwww~. Copulation isn't generally something I would describe as cute, but when it's a pair of nautilus, it's just adorable.
