They think that behavior came from avoiding whale predation [13:10:13] Found it! [13:10:20] (Tina) it was plenty) [13:11:02] (Tina) and black coral at the top, or Acanella [13:11:28] Hoplostethus occidentalis ? [13:11:38] there is another one in distance))) [13:12:20] (Tina) [13:12:58] what is the one in front of Dendrobrachia? Anthothelid???? or?? [13:13:28] Yes, I think Anthothelidae [13:13:41] interesting that this coral community looks more NE Atlantic than NW [13:13:43] (Tina) no... I think Plexaurid.. [13:14:15] Sorry - am paying attention to the Dendro and the databasing here on ship! [13:14:17] bit thin... would be Plexaurid..

[13:15:31] @Carlos interesting! did you collect them? [13:15:41] ashleymarranzino leaves the room [13:15:41] daphnecuvelier leaves the room [13:16:02] MARECO dives recorded "white orange roughy" hanging out with orange orange roughy. [13:16:06] (Tina) or just take all. [13:16:12] (Tina) Swiftia perxaps.. or else) more probably else [13:16:33] yes we saw pink Swiftia -like colony earlier this dive [13:16:40] We collected a sample of a very similar looking colony that was id as Muriceides, but that was at 500 m (also in the MAR) [13:17:00] Thanks Carlos! [13:17:21] (Tina) Swiftia are often white [13:17:33] @Scott how about to collect this white Plexaurid? [13:17:49] Yes, stand by for pilot to complete this collection [13:17:53] (Tina) Muricides is another good guess [13:18:19] We have to lift off in order to open the drawer to stow the sample. [13:18:27] We aren't leaving [yet] [13:19:01] stand by [13:19:17] LAT : 40.452843 , LON : -29.907865 , DEPTH : 1174.0623 m, TEMP : 6.31312 C, SAL : 35.18387 PSU, DO : 6.98098 mg/l, TURBIDITY : 0.9768 FTU [13:20:17] watch camera 2 to see down into box [13:20:22] Just have a few minutes this AM. That silver-gray macrourid with enormous eye, long pointed snout and row of scutes along the dorsal fin = Trachyrinchus scabrus - a common NE Atlantic species, but I have never seen in imaged subsea before [13:21:16] hey Ashton and Scott! [13:22:23] Trachyrinchus is the genus that gave the rattails their other name 'grenadiers' because the long pointed snout resembles the tall pointed hat of British grenadier soldiers - soldiers with rifles able to lob grenades [13:22:36] Hi Deb! [13:24:04] now we can see it [13:24:18] LAT : 40.452888 , LON : -29.907852 , DEPTH : 1176.68 m, TEMP : 6.34546 C, SAL : 35.18535 PSU, DO : 6.93032 mg/l, TURBIDITY : 0.9463 FTU [13:26:43] please don't hesitate to cut large piece :) [13:26:52] What was the suggested ID on this one? Swiftia? [13:27:23] maybe...but another possiblity is Muriceides [13:27:45] Oh right - Muriceides. Thanks [13:27:46] I just say Plexaurid... [13:28:17] or Muriceides of course [13:28:53] The small spiny eel seen just after the Trachyrinchus rattail = Polyacanthonotus merretti, named for Nigel Merrett by me in recognition of his great contributions to knowledge of NE Atlantic deep-water fishes [13:28:57] Thank you for the collection!! [13:29:04] Amazing work!

[13:32:47] Could this be Thouarella? [13:33:00] no, its not hydroid [13:33:41] agree, could be Thouarella [13:33:43] shrimp behind coral [13:34:19] LAT : 40.452768 , LON : -29.907721 , DEPTH : 1169.7782 m, TEMP : 6.44712 C, SAL : 35.19511 PSU, DO : 6.87154 mg/l, TURBIDITY : 0.9341 FTU [13:35:43] Mike - Caelorinchus and Trachyrinchus are very similar (although different subfamilies). The character to look for is the sawtooth row of scutes running along the base of the dorsal fin on each side and onto top of head. In some frame grabs today, I could see that row clearly [13:36:20] Hemicorallium tricolor [13:36:49] The bluish gray fish with very long dorsal fin filament, long pelvic fin barbels is the Moridae fish Lepidion, but could be either L. guentheri or L. eques [13:37:40] Thanks to the pilot and camera person - working together nicely to capture close-ups of even moving fishes today!! Credit due to skill shown [13:38:18] Thanks Ken [13:39:19] LAT : 40.452748 , LON : -29.907689 , DEPTH : 1167.6857 m, TEMP : 6.45299 C, SAL : 35.19612 PSU, DO : 6.88242 mg/l, TURBIDITY : 0.9402 FTU [13:41:06] @ken - I was just rewatching the video of Trachyrinchus. There is a pale organ that appears to be directed into the eye - looks almost like the eye-facing photophores in stomiiforms. Is this species bioluminescent? [13:42:03] Scott - you are right, the long pelvic feelers and the long chin barbel in Lepidion are both sensory. That long barbel suggests species ID = L. guentheri. The tall black first dorsal ray is possibly not sensory but a species recognition character. According to the sunlight extinction coefficient in purest sea water, no photons remain below 1100 m. So why have a visual species recognition character. In this case the species ranges well above that critical light extinction depth. [13:43:10] coral with ctneophores [13:43:26] same J1 clade? sorry I was out of the room for a bit [13:44:20] LAT : 40.452855 , LON : -29.907666 , DEPTH : 1166.9539 m, TEMP : 6.46728 C, SAL : 35.20783 PSU, DO : 6.87499 mg/l, TURBIDITY : 0.9463 FTU [13:45:20] no, looks like Eknomisis.... my bad [13:45:26] (Tina) no... do not think so. differet barching pattern in collected branching [13:45:27] daphnecuvelier leaves the room [13:45:45] Whew! [13:46:07] re: Eknomisis ID. I was beginning to think I knew nothing of bamboo coral ID! [13:47:03] (Tina) Leiopathes [13:47:30] Ashley - interesting question. Some macrourid genera have a bioluminescent organ ventrally near the anus, a 'window' allowing the luminescence of gut bacteria to shine through. Used for intraspecific recognition. But I do not know of a macrourid with a post ocular photophore. However, I just zoomed in on my frame grab and note that your observation is worthy of consideration. There is a definite tiny white spot on the upper posterior area of the eye. Also, this enormous eye has a nice keyhole aphakic space, meaning this fish is equipped to rein in all the photons it can - presumably pursuing bioluminscent nekton. This is a nekton feeder, not a benthic feeder. [13:47:32] carlosdominguezcarrio leaves the room [13:47:43] (Tina) it is interesting. some rocks are just perfect in terms of biodiversity) if they attract each other? [13:47:49] could be a I. fontinalis or maybe I. pourtalesi. lazers on it? [13:47:51] (Tina) ask zoom on Leiopathes? [13:48:02] brief closeup please [13:48:25] has shrimp, Bathypalaemonella serratipalma or other species [13:48:48] elisabettamenini leaves the room [13:49:00] such a beautiful shot!

[13:50:31] I know this is tough but a live piece of this with the great images would help to establish what that species really does look like [13:51:31] after the money shot can we have lasers? [13:51:44] (Tina) like no space left between tentacles of polyps from closeby pinnules [13:51:52] (Tina) and like batteries of bumps between them [13:52:01] alainahebert leaves the room [13:52:13] the bumps are clusters of cnidae [13:52:17] (Tina) and pinnules are not staright, but like bow... [13:52:49] (Tina) take 10 cm)) [13:53:09] Do you need the main axis as well, or just pinnule?

Both are passive drifters and scullers that hang around corals and dropoffs - opportunistic mesovores of small mobile inverts. [13:58:09] might as well cut low [13:58:36] Sorry to always be behind the video. Keep getting bumped off the video and chat streams [13:59:07] Ken: are you using the science low latency feed?

[14:03:21] (Tina) just got sad news that Myriam Sibuet, French deep-sea biologist and ecologist, died yesterday morning [14:03:30] as background, what is left of the type of I. pouralesi is just a few polyps. The branches and axis that was collected during the 1800s has all been lost.
