Which is also why I suggested this area (I had suggested the western one as well).

[16:06:14] johnreed leaves the room [16:06:16] @Scott that's what I thought at first too but aren't the polyps on alternate sides in S-1? [16:06:44] Just looking for name for the collection. Thanks [16:09:25] I would call this Keratoisididae ?KerJ3a [16:09:29] LAT : 24.380765 , LON : -84.110932 , DEPTH : 2426.05 m, TEMP : 4.32286 C, SAL : 34.9753 PSU, DO : 6.79829 mg/l, TURBIDITY : 0.8547 FTU [16:10:06] Thanks [16:11:43] christophermah leaves the room [16:13:55] I'm just looking through my database at the Nashville Seamount samples (the ones that had no nodes), and sure enough they have polyps that resemble these ones (squat with very long tentacles). Those were collected at 2246 m and so remarkably consistent with this depth. These were genetically clade kerJ3a. When I search my database for that type, I find 3 additional specimens from the deep Bahamas! (Bahama Escarpment at 2073 m) So I suspect that is what this will turn out to be (it is as yet an undescribed species in an undescribed genus), and this will be the first record for the Gulf of Mexico.

Will be very interested to hear if, when you look at it in the wet lab, you see any nodes. [16:15:23] Nice. [16:15:35] stephaniefarrington leaves the room [16:16:08] Hopefully we get some nodes. We will make note of what we see in the wet lab for you Scott. [16:16:55] @Allen: I'm actually expecting there will be NO nodes. That is the really cool thing! Kind of the bamboo coral equivalent of a cladorhizid: a bamboo coral without the defining nodes! [16:17:08] D'Oh! so much for all of that... [16:17:13] meganmcculler leaves the room [16:17:31] Thanks much for that collection! [16:17:42] allencollins leaves the room [16:18:27] Later we should be up on top of the crest so collections shouldn't be so difficult. But I have been in too many situations where we say "Lets wait and coillect the next one we see" and we never see it again. So the challenge was worth it, IMHO. [16:18:58] For sure Scott.

[16:25:21] @Scott I don't really follow the associate collections unfortunately. Tim S might know [16:25:53] Okay. Mary W was saying that these are either unsampled or undersampled in the GoMex. [16:25:58] Heteropathes sounds right to me too. [16:27:00] cool! [16:27:06] Small victories! [16:29:04] Looks like Paramuricea [16:29:15] could be P. biscaya [16:29:28] looks like maybe a small white branching bryozoan to the left of the corel [16:29:31] LAT : 24.380775 , LON : -84.111009 , DEPTH : 2419.5775 m, TEMP : 4.32192 C, SAL : 35.00618 PSU, DO : 6.79066 mg/l, TURBIDITY : 0.8974 FTU [16:29:32] would be great to collect if possible [16:30:27] yes bryozoan [16:30:48] georgesedberry leaves the room [16:30:50] we are finding that the west florida escarpment could be a source of larve for populations affected by the DWH oilspill. It would be imporant to figure out if these are the same species [16:31:19] Santiago, interested in teh Paramuricea when we find another? [16:31:30] yes please [16:31:31] stephaniefarrington leaves the room [16:31:40] Would be good to get one with ophio in it (if we find that) [16:32:13] yes, absolutely [16:32:28] stepping away for ca. 15 min.

So not a taxonomic characteristic, but an ecological one... [16:35:16] we have seen them hoping from one colony to another [16:35:54] So if there are lots of previous collections from the GoMex, what is the attraction for this specimen? [16:36:41] I don't think this is species is known from this far south in the gulf, so it could be a new/different species [16:37:22] we are finding that the west florida escarpment could be a source of larve for populations affected by the DWH oilspill. It would be imporant to figure out if these are the same species. Knowing this would be iimportant form a management perspective [16:37:53] @Santiago: thanks, that is helpful.

[19:35:16] @Megan Same! [19:35:48] I'm in maze of time zone... [19:35:51] now on land I don't have that so it's a wonder I ever know what day it is [19:36:42] @Megan If I didn't have google calendar, I would be completely lost! [19:37:01] @Nolan yeah google calendar is a life saver [19:38:24] @Scott Maybe analogous to plant galls induced by wasps? [19:39:22] feet are called "cirri" [19:39:50] LAT : 24.380645 , LON : -84.109046 , DEPTH : 2353.9387 m, TEMP : 4.31729 C, SAL : 35.00185 PSU, DO : 6.76352 mg/l, TURBIDITY : 0.873 FTU [19:41:10] @Nolan: nice! That is a great comparison. [19:41:20] @Scott Glad it was a useful analogy! I'm leading a plant-walk this weekend in the Georgia Mountains so it was on my mind! [19:41:35] @Nolan @Scott actually there exist coral galls! I thought Pal Mortensen and Lene Buhl-Motensen published the paper [19:42:08] @Asako Oh really? Gotta see this paper now! [19:42:11] @Asako: sure - ascothoracicans for sure, perhaps others created by polychaetes. [19:42:47] Lovely view of the sponges! [19:43:24] There is probably some simple mathematical explanation for the regularity of that sponge architecture... [19:44:19] @Scott Well the math must produce imaginary numbers when they produce amorphous blob sponges!

[19:45:35] @Asako Is the paper you are talking about showing a copepod producing a gall on Paragorgia? [19:45:45] @Scott XD [19:46:09] meganmcculler leaves the room [19:46:17] @Bob: cool! Does it explain the algorithms behind the biology? [19:46:20] @Nolan I suppose so! [19:46:24] May have to order that... [19:46:45] ophiacanthids [19:47:30] iscwatch leaves the room [19:47:53] @Robert oh, Jaap Kaandorp! I have that book [19:47:57] @Scott haven't read that particular book. Similar books "Algorithmic beauty of....." for gastropods and plants have been good. [19:48:20] So neat!

[19:51:34] I'm surprised at the lack of large sea star or urchin predators on these colonies. In the pacific it was quite common to see at least a few per dive. [19:51:49] white branching bryozoans right beneath this coral [19:51:59] @Nolan I think this is the one https://www.researchgate.net/publication/235700045_Crustaceans_associated_with_the_deep-water_gorgonian_corals [19:52:14] @Asako We cannot see what you just posted [19:52:19] Paragorgiidae [19:52:40] cristianacastellobranco leaves the room [19:52:47] nevermind are those those really small corals [19:54:51] LAT : 24.380613 , LON : -84.109001 , DEPTH : 2357.6844 m, TEMP : 4.31773 C, SAL : 35.00201 PSU, DO : 6.74161 mg/l, TURBIDITY : 0.8669 FTU [19:55:09] https://www.tandfonline.com/doi/abs/10.1080/0022293031000155205 [19:55:10] spoke too soon! There is our predation event [19:55:24] the culprit [19:56:16] @Asako Still not seeing it. Are you copying and pasting an image or a hyperlink? [19:56:31] Lepadaemorph barnacles [19:56:42] I still want to call them bryozoans but those little stylasterid corals trick me [19:57:10] @Nolan I don't know. I just googled it, got the page and just copied the link! [19:57:41] I know Megan. Look like stylasterids to me, but I don't feel I know enough bryo growth forms to be confident [19:58:47] christophermah leaves the room [19:59:30] @Nolan sorry it was not the one. same author but different. [19:59:48] @Allen and I don't know enough about stylasterids to be confident ..hah!

What we are seeing is [object Object]. [20:01:58] Maybe its just me since I'm logged in through the tgfoe.org website? [20:02:45] Some of those little white branching things are bryozoans [20:03:34] yes a chrysogorgiid. I think different than the one from this morning [20:03:36] chrysogorgia [20:03:48] either planar bi-planar [20:03:52]
