Here a project that I worked on a while ago that just got published.

cool and congrats! That sounds like it'll be of great interest to the gut-contents specialists among us!

Fantastic! The crowd in Gilly's lab will be excited to read this.

This is truly EXCELLENT stuff! Adam, congrats and thanks for sharing! (I'm catching up with George tomorrow; he's in the country now).

"Following a change in diet, the fatty acid profile of the cuttlefish digestive gland reflected that of the new diet within 14 days. The results confirm that the fatty acid profile of the cuttlefish digestive gland clearly reflects the profile of its recent diet. It also shows that the digestive gland may not be an organ that accumulates dietary lipids for long-term storage, but rather is an organ where lipids are rapidly being turned over and potentially excreted."

Thanks Adam, good stuff!

Interesting stuff. I often wondered about the function of the digestive gland. If indeed it was storage for lipids etc then one would expect to see it shrinking in non feeding periods (assuming the storage was there to be used) which I did not see in the albeit small number of mature N. sloanii I had. Hmmmm food for thought there.

Say Hi to George from me when you see him!

Awesome! Congrats on getting published also, excellent read.

Nice! :notworth:

Congratulations, Adam!

Steve's empty stomached whales bring up a question for biology neophyte. Is there something similar to the digestive gland in mammals?

Hey, congratulations!!!!

well done :)

I think it shares some of the digestive functions (but not the blood filtration functions) with the human liver, but I'm nervous about going out on a limb like this with all the squid-gut-physiologists out there. The wikipedia squid page does say "liver (or digestive gland)" which gives me confidence to at least post, but they're at least as likely to get the details wrong as I am....

very nice and Congratulations! *smile*

It's classified as a hepato-renal gland, so has functions somewhat similar to a liver/kidney complex.

Congrats marinebio guy!

Hmm, so it has a digestive and a filtration/excretion function, like a mammal liver? That seems surprising... I wonder if that implies that excretion and digestion were combined in an organ in the last common bilaterian ancestor? I don't know much about guts, livers, and such in invertebrates, though, so I'm really just thinking on my feet here... I'm sitting in on a class that's in the midst of covering the evolution of the bilateria so it's on my mind...

seems too, check out http://www.ingentaconnect.com/content/els/00220981/2002/00000274/00000001/art00165

A slight digression, but we did catch up with George this week, seen here with Kat (aka Tintenfisch).

Great pic! Two cephy greats in one photo -- thanks Steve.
