Some individuals have been found to produce a compound called aphrocallistin which inhibits the growth of a panel of human tumor and most impressively shown to induce G1 cell cycle arrest in a pancreatic carcinoma cell line. Hopefully it might be developed into a treatment to treat pancreatic cancer. [16:46:40] Beautiful imagery as usual!

We have collections of Keratoisis D1e from this general area and depth (but not with in situ images unfortunately).

[17:15:44] So far we have sampled a swimming polycheate and a bryozoan on this dive [17:17:48] taraluke leaves the room [17:18:53] LAT : 32.091723 , LON : -77.668436 , DEPTH : 725.6527 m, TEMP : 8.2206 C, SAL : 35.07873 PSU, DO : 4.5867 mg/l [17:18:55] @Alexis: that is my best guess given i) they are quasi-planar internodal branchers, ii) the general area and depth. I'd need to look back at the collections from last year to see if one of these colonies was sampled. If we have time and space, then if one wasn't sampled last year a collection would be great to link morphology/genetics to these great in situ images. [17:21:09] Those barnacles might be a species of Megabalanus [17:22:26] okay thanks for the info @scottfrance I can check with @kaseycantwell about last years samples [17:22:28] @Megan Mega makes sense! Those were quite large! [17:22:29] @Alexis: just checked and no collection was made of this white planar bamboo coral on EX1806, so I think it would be a legitimate option for collection if it has been common today. [17:22:41] Zoom on sponge please? [17:22:46] okay great thanks for doing that digging! [17:23:34] @scottfrance hopefully we continue to see them on our way up! [17:23:40] @Alexis: no problem.

[17:24:37] I thought Enallopsammia only had polyps on one face, so I'm learning something. [17:25:50] Yeah @scottfrance that is what i thought until we started to doing to DeepSearch work! This Enallopsammia profunda is common here and has polyps all the way around [17:26:18] much different from E. profunda I've seen in the gulf and pacific [17:26:24] @Alexis: yet another example of why we need to have the opportunity to do the surveys and sampling!
