[15:16:45] @nolan the coral near the sponge [15:16:45] alexisweinnig leaves the room [15:16:52] jaylunden leaves the room [15:16:56] I think it is Scleractinian [15:17:39] @ChrisK Good morning! [15:18:02] I agree with Chris on the genus name of that hexactinellid. It does look like a Regadrella. (Chris is way more familiar with hexacts than I am, so I will defer to his diagnoses! Thanks, Chris! [15:18:16] @Iris I didn't get a good look at the coral [15:19:11] A dumb question from out in the pacific, how deep do these Lophelia/Enallopsammia bioherms get down to?

[15:23:12] Hyalonematidae [15:23:20] It has a lophophytus attachment which rules out a lot of things. [15:23:29] ? [15:24:06] Can you take a look at the feather star below the stalked sponge? [15:24:15] Hi @Chris, on the New England seamounts we saw both Enall... and Lophelia down to maybe 2000 m, but not in large bioherms like this [15:24:52] Also, judging by the Mn coating, these are quite old dead skeletons [15:25:00] Thanks to Cheryl and Les for their answers.

[15:28:17] Sabellid polychaete? [15:29:25] No - 8.5 degrees! [15:29:44] @sci: in situ temp is 8.5 degreesC [15:30:03] If this is Oculina then there could be metapseudid tanaidaceans. Apseudomorpha.

Not sure what is going on. These abundant little feather stars may be an undescribed species. [15:32:17] not sure about Enallopsamia in this are [15:32:33] Thanks @Erik, and it likes higher salinity as well, I think [15:33:15] I have no idea what's going on with that sponge [15:33:52] Those are really weird but I think they are glass sponges, perhaps rossellids [15:34:02] can we zoom to the brownish/cream colored material? [15:34:04] collect?) [15:34:20] Maybe pheronematids??? [15:34:31] because they are identical [15:34:54] @ScottH - will do. [15:35:03] irissampaio leaves the room [15:35:27] Yeah, very curious beasts!

Looks like the sediment we see here. [15:36:25] Nolan, rossellids can also have a lot of fibers coming off their sides so who knows what those were. [15:36:35] I had a serious delay... [15:37:45] @scotth - sorry, didn't know what you were referring to. [15:38:08] Pheronema ? [15:38:17] @ChrisK Amazing [15:39:11] Iris, I don't know that genus well since we dont have it out here but that certainly would be a possibility [15:39:36] truly similar with our NE Pheronema carpenteri [15:40:21] The only real difference I see on this sponge is the amount of sediments bound up in the attachment spicules. But I'm not a sponge expert!

[15:41:52] I just looked up images of Iris' suggestion and I agree, it sure looks like it could be that or something close to it. [15:42:20] If it is Pheronema carpenteri, the good thing is that that is a species on the Connectivity target list. [15:42:33] @ChrisK I just did too. I agree [15:42:49] I had stepped away and just caught the last glimpse of the feather star. Was that the one that was swimming/drifting? [15:42:58] irissampaio leaves the room [15:43:06] I... I do not particularly like pteropods [15:43:28] @charles, it was sitting calmly [15:44:03] yey! a Pheronema [15:44:52] A bleach prep and a quick look under the scope would easily confirm it to family at least. Pheronematids have very distinctive spicules called amphidiscs. [15:45:01] @Chuck: yes - looked to be a combination of being caught in the current or ROV wash and "swimming: [15:45:17] ...or at least waving its arms wildly! [15:45:31] If it proves to be P. carpenteri it would be the very first record for the NW Atlantic [15:45:50] LAT : 30.403805 , LON : -79.598517 , DEPTH : 778.6495 m, TEMP : 8.51712 C, SAL : 35.08928 PSU, DO : 4.16497 mg/l [15:46:04] @joana great news!!! [15:46:18] @Joana That would be really exciting [15:46:28] If you have trouble with the scoop, I think you can just grab the sponge. It will be kitchen sponge-like, not brittle [15:46:47] @Chris: one persons "distinctive" is another persons "huh"? :-) [15:47:18] No record that members of this genus can swim, although they might, but the current is strong enough to suggest that it might have drifted off a perch. [15:47:47] @Chuck: that is more what I saw. It was moving too fast to be simply swimming. [15:48:20] Amphidiscs look like 2 umbrellas with their handles cut off and glued together in opposite directions so you have a little umbrella at each end of a rod [15:49:00] erikcordes leaves the room [15:49:10] Great collection! Thank you and I am looking forward to see what it is! [15:49:25] @Sci, when you look at this scooped organism, look closely at the upper rim to see if that is sediment incorporated into the organism and if it is similar to the loose materials scooped. [15:49:36] I agree, great collection but I'm biased of course. [15:49:59] ah... I see that there's another species of Pheronema reported for the NW Atlantic, Pheronema annae which is also not a well known species, so either way this is a very interesting finding [15:50:18] Darn have to go get ready for work.

S. farallonesica is white but unbranched, so what we are seeing are not this species but it shows in situ photo by ROV. their polyps are large and let me know quite difficult to distinguish them. [18:04:59] @scott, Eunicella my guess [18:05:33] in Anthothela polyps are much bigger [18:05:56] There was at least one white stem with that sponge, so we can possibly solve "Anthothela"/"Eunicella" question.
