OkEx expedition to the general region SEUS, but based on the email from Tom the other day I would say we have "seen" most things on these mounds, but not necessarily collected them. The note from Tom was a very good example of something we assumed had previously been sampled, but has not (I'm referring to the Aphanostichopathes). At least, not collected with D2. Not sure what the Deep SEarch folks have sampled (though apparently not a Aphanostichopathes).

And too late now! ;-) [15:23:01] @Allen: I mean I did not realize dactlyozzoids were simply modified tentacles (or I forgot!). Makes a lot of sense.

I used to key on the bulbed tentacles, but Daphne F corrected me on that! I usually look for a diaphanous appearance - very transparent body wall. [15:40:38] So I would have called that last orange one an anemone. [15:41:00] But I really don't know. [15:42:06] New Zoanthidean species & genera were named from Aphrocallistes earlier this year from the IndoPacific, so these maybe new to science [15:42:09] Hello - just on for a few minutes. Nice dead Lophelia landscape - friendly to fishes. The medium-sized darkish ophidioid cusk eel with 2-rayed pelvics is Neobythites gilli. The synaphobranchid eels are most probably Synaphobranchus affinis at this depth (too shallow generally for S. kaupii). That head-shaking behavior and bumping into the substrate is because the ROV lights blinded the fish. When really annoyed by getting light blasted, cutthroat eels will gape and snap the jaws violently. The ROV is not benign - it affects the behavior of fishes observed in various ways. [15:44:02] Actually it was Aphrocallistes beatrix from West Africa: Guinea and Cape Verde at depths of 580–800 m. [15:44:15] If you want to see previous OkEx collections in this area, have a look at dive reports from EX1806 dive 5 through 8 and EX1903L2 dives 2 through 8 and EX1907 dives 1 through 8 (the latter Stephanie was on and collected a fair number of sponges) [15:44:26] LAT : 28.539256 , LON : -79.262934 , DEPTH : 820.5703 m, TEMP : 6.97223 C, SAL : 35.12603 PSU, DO : 5.93228 mg/l, TURBIDITY : 0.8974 FTU [15:44:39] The new zoanthidean genus & species are Vitrumanthus vanderlandi [15:45:23] the weird brittle star. [15:45:31] we saw this last time out.. I thnnk its new [15:46:07] but you are right the disk is fleshy [15:46:17] You should suction! [15:46:24] suction is better.. [15:46:35] We'll be here all day if you try to pick it up with claw. [15:47:06] I have a question for the Invert experts. Why is that sponge (and also others of different morphology in the GOM) intensely blue??? I suppose I will get the standard answer that this is an incidental thing, a byproduct of physiology with no adaptive function. I do not believe that. Same question for the semi-colonial (groupy at least) solitary coral Rhizopsamnia, which is very unusual in being jet black when alive. Both live at the bottom of the mesophotic zone, where a small fraction of the sun's photons still survive unabsorbed. Could the blue sponge and the black cup coral be particularly sucking up those precious photons and supplementing their energy budget via photosynthesis???

So the challenge now is to match thos observations in the video to polyp scalse varaition to see if they are specieis specific. For that reason, if we stop to image a bamboo whip, I always ask to pan acrtoss the colony so that we can accumulate these observations such that in future we can acurately make an identification from video snap shots.

(so far as I recall) [19:48:23] @Tina: no. We have been looking! [19:48:59] This is all scleractinia... [19:49:54] LAT : 28.539521 , LON : -79.260418 , DEPTH : 776.571 m, TEMP : 7.80423 C, SAL : 35.11159 PSU, DO : 5.12018 mg/l, TURBIDITY : 0.8608 FTU [19:50:23] Enallopsamia never has intertentacular budding [19:51:01] Just all looks like dead scleractinian to me. [19:51:35] styla [19:54:55] LAT : 28.53954 , LON : -79.260367 , DEPTH : 772.513 m, TEMP : 7.59139 C, SAL : 35.13357 PSU, DO : 5.34885 mg/l, TURBIDITY : 0.8669 FTU [19:56:39] Ye olde Keratoisis [19:59:02] Well, that could nbe a young bubblegum coral... [19:59:06] ершы щту цушкв [19:59:10] sorry [19:59:16] this one is weird [19:59:22] Which would explain the lack of a "bulb" [19:59:29] :) Good one Tina. [19:59:40] I did not have a close enough look. [19:59:55] LAT : 28.539561 , LON : -79.260289 , DEPTH : 770.491 m, TEMP : 7.50091 C, SAL : 35.12829 PSU, DO : 5.43914 mg/l, TURBIDITY : 0.8669 FTU [20:01:18] I will look back [20:02:09] That Geodia looked a little bit like what Paco mentioned the other day it can be G. pachydermata [20:02:51] Collecting the yellow sponge may be interesting since it is one of the most common after the Euplectellids!! [20:04:10] timothyswain leaves the room [20:04:55] LAT : 28.539553 , LON : -79.26025 , DEPTH : 769.1528 m, TEMP : 7.39316 C, SAL : 35.12728 PSU, DO : 5.48214 mg/l, TURBIDITY : 0.8669 FTU [20:07:29] YEEEAH! [20:07:30] Just grab skeleton below it. [20:07:36] Pseudoanthomastus under sponges [20:07:40] Any ideas [20:08:06] Any ideas beyond Hexact? [20:09:56] LAT : 28.539623 , LON : -79.260168 , DEPTH : 767.3267 m, TEMP : 7.2747 C, SAL : 35.11438 PSU, DO : 5.52105 mg/l, TURBIDITY : 0.8669 FTU [20:10:23] No Ideas from here Allen, that is one unique on your ally! [20:10:52] christophermah leaves the room [20:11:01] So excited to see this one! [20:11:17] Dignified cotton candy!!! [20:12:19] Allen place some pieces for histoloogy and/or TEM just in case you get some reproductive stuctures [20:12:37] OK, into formalin with some then? [20:14:30] emilycrum leaves the room [20:14:49] In the past if the sponge is very large, we dry the bulk of it following appropriate preservation of chunks of tissue for DNA and spicules. [20:14:56] LAT : 28.539619 , LON : -79.260155 , DEPTH : 765.9831 m, TEMP : 7.45507 C, SAL : 35.14722 PSU, DO : 5.36089 mg/l, TURBIDITY : 0.8608 FTU [20:15:29] Canb you reiterate to pilot to simply grab the coral skeleton below the sponge. and not the sponge itself. [20:16:16] like flowers [20:16:24] Oh, what an elegant collection!!!! [20:16:36] Okay - maybe not necessary. I find it VERY difficult not to have the pilots on stream 1. I miss a lot of context and it takes too lonmg to keep changing camera feeds. [20:17:14] allencollins leaves the room [20:17:18] urchin at 1 o'clock [20:18:18] I totally would feel that way @Scott. [20:19:32] allencollins leaves the room [20:19:57] LAT : 28.539629 , LON : -79.260162 , DEPTH : 765.5223 m, TEMP : 7.79969 C, SAL : 35.13589 PSU, DO : 5.01127 mg/l, TURBIDITY : 0.8669 FTU [20:20:49] I like hearing pilots and back and forth with bio/geo leads when listening in. A few times it is confusing, but mostly it gives much better sense of what is going on [20:21:18] Yes, and at times tha is critical. [20:21:44] Helps keep my backseat driving to a minimum if I know what is happening in the front seat! [20:21:59] aha. [20:22:20] "rabbitfish" [20:22:37] this one is absolute rabbit [20:22:39] But ghost sharks are also chimaeras. [20:24:51] No - no black corals today [20:24:57] LAT : 28.539674 , LON : -79.260084 , DEPTH : 767.1384 m, TEMP : 7.5635 C, SAL : 35.1293 PSU, DO : 5.34697 mg/l, TURBIDITY : 0.8608 FTU [20:25:47] @Tim, we have Aphrocallistes from Atlantic with zoanthids at NMNH. Will try to find them for you if you are interested. Not sure they are in formalin though [20:26:37] This one does not tapper to the tip, it might be more like Vazella species, maybe [20:26:57] What is the angle here? [20:28:48] @allencollins Always interested, but particularly if paired samples for DNA [20:29:57] LAT : 28.539665 , LON : -79.259955 , DEPTH : 767.4506 m, TEMP : 7.65238 C, SAL : 35.12742 PSU, DO : 5.27572 mg/l, TURBIDITY : 0.873 FTU [20:34:28] The Previous one, had the upper part wide, but this one with the decrease diameter on the upper part, it is quite different and common today [20:34:58] LAT : 28.539641 , LON : -79.259908 , DEPTH : 765.522 m, TEMP : 7.77763 C, SAL : 35.13777 PSU, DO : 5.10594 mg/l, TURBIDITY : 0.8608 FTU [20:35:50] It could be Regardella [20:36:41] Yes indeed @mariadiaz [20:36:58] yes.. Araeosoma [20:37:02] Just joined in time for a neat sponge! I was leading a field trip. How was the dive today? [20:37:07]
