Its probably because it was a copy/paste issue and I'm using the website to access the chat, not my usual Pidgeon. [19:26:28] @Stephanie Thank you! Its funny that we never met in person, since I was at HBOI for a span of 3 years. But I was a student of Amy's and Shirley (along with Deb Glickson) got me involved with the OKEX in the first place.

[20:19:42] No worries! I've learned a lot from Chris Mah! [20:20:56] @Maria Are these blue sponges in the family Desmacellidae? [20:21:30] I do think they might be Hemimycale [20:22:05] let me check the family. [20:22:16] Same family than Hymedesmia. [20:22:30] Yes, I just saw that on WORMS [20:22:35] Thank you!

I'm taking notes! [20:25:56] What made you think on Desmacellidae Nolan?

I have notes from one of John Reeds pubs with pictures of distant blue encrusting demosponges that he called Desmacellidae. In the same image there were also white fan sponges that he called Phakellia sp. or at least Axinellidae family.

[20:35:21] What has happened? [20:35:27] no sound? [20:36:23] okay. There are blue sponges in many genera of Demospongia. [20:36:31] Off bottom for ship re-orientation. The ROV pilot line still has sound. [20:38:02] LAT : 24.369263 , LON : -80.708143 , DEPTH : 326.6879 m, TEMP : 9.792 C, SAL : 34.68158 PSU, DO : 3.8521 mg/l [20:38:12] Ahhh okay. Until that pub, I would ask about blue sponges and people would say "blue encrusting demosponge" because they are so hard to collect for ID. Originially, I was interested in the chemistry that gives them blue color. Blue color pigments are rare in nature.
