I think H. phrygiana but H. heathi among others are recorded from this area. [18:02:53] lovely! I think H. phrygiana predators on cnidarians [18:03:05] almost everything we see is prob. eating something cnidarian [18:03:20] LAT : 53.293528 , LON : -169.776044 , DEPTH : 779.9834 m, TEMP : 3.49695 C, SAL : 34.11899 PSU, DO : 0.92489 mg/l, TURBIDITY : 1.0073 FTU [18:03:26] My thanks Rhian! [18:03:39] So, I ran the coral snipping sequence in a series of freeze frames. The very pale eel-like fish sheltering within that coral appears to be a zoarcid, eelpout. Fairly large eye, bluntish head. Most zoarcids are bottom sitters, a few associated with thermal vents. I do not recognize this eelpout, but looks like genus Lycenchelys. [18:03:44] jenniferaschoff leaves the room [18:04:30] I have lost track - what is this Dive number? [18:04:36] the other corals are Callogorgia and Plumarella? [18:04:40] Dive 7 [18:05:08] we cannot see sclerites.... [18:05:33] I don't think this is Primnoa [18:05:56] but still interesting. [18:06:21] oh, I can see small sclerites. [18:06:44] kennethsulak leaves the room [18:07:00] It might be the species described by Bob Stone?? not sure.. [18:08:06] the feather like branching would be Callogorgia?

[18:08:55] @Scott do you mean just passed by? or the one we had close up? [18:09:50] @Asako: Sorry - I was only half paying attention, but it was one that was being closely imaged. [18:10:23] Looking at the polyps I don't think it was.....it was strange! [18:10:56] @Scott it had only small few polyps. [18:11:10] sorry *sclerites [18:11:26] please close up the purple something [18:11:29] Note the single armed gorogonocephalid.. Astrochele laevis! [18:11:40] can we get a zoom on those? [18:12:14] wow beautiful. Thank you for the up! [18:12:36] ElainaJorgensen leaves the room [18:12:38] I had the same experience coming across one in the Emperor's. I stared at it for the longest time completely mystified, and Sarah Bingo said it was obviously (to her) a Primnoa, which upon collection we discovered itwas. But, I confess, I did not see the close-ups today, so don't take my statements with too much authority. [18:12:43] the single branch one looks different. [18:13:21] LAT : 53.293425 , LON : -169.776101 , DEPTH : 775.8675 m, TEMP : 3.5012 C, SAL : 34.11595 PSU, DO : 0.92532 mg/l, TURBIDITY : 0.9463 FTU [18:13:52] YAY for the mafic igneous rock!! [18:14:20] yes! thanks Chris! [18:15:00] Can we zoom in on the large bushy colony in front? Might be large hydroid [18:15:06] Taking a sample of this one - maybe it is Pirmnoa but has different polyps/scleraites - Scott? [18:15:10] @Scott Thanks. now it might be Primnoa...Actually this is the first time for me to see N-EAST Primnoa underwater. [18:15:28] emilycrum leaves the room [18:15:48] @Rhian, [18:16:04] I only have seen N-WEST Primnoa pacifica in the water!!! [18:16:15] Yes I agree with Primnoa ID. They always fool me from a distance and I want to type "bamboo coral"! [18:17:41] jenniferaschoff leaves the room [18:18:22] LAT : 53.293454 , LON : -169.776223 , DEPTH : 775.5154 m, TEMP : 3.51324 C, SAL : 34.11546 PSU, DO : 0.93948 mg/l, TURBIDITY : 0.9341 FTU [18:18:37] Looks like a tight association between the unpigmented fish and the soft coral. My first guess from freeze frames was wrong - NOT a Zoarcidae. Instead, I think this is an Ophidioid pearlfish. Some are tightly associated with sea cucumbers as inquilines. Others with starfishes. I do not know of a pearlfish described as associated with bubblegum coral or any coral. Could be an undescribed species [18:20:32] might be Primnoa wingi Cairns & Bayer, 2005? [18:20:42] another possiblity [18:21:24] jenniferaschoff leaves the room [18:23:22] LAT : 53.29341 , LON : -169.7761 , DEPTH : 774.8544 m, TEMP : 3.5172 C, SAL : 34.11339 PSU, DO : 0.93581 mg/l, TURBIDITY : 0.9341 FTU [18:23:52] I wonder if it is - i've been looking at my close up images of P. pacifica polyps open and it's not quite the same with that ring around it. I'll look at hte sample when it comes up! [18:24:21] I don't know how to tell those species apart in situ. [18:25:49] @Rhian that is why I mentioned as P. wingi [18:25:57] ChristinaConrath leaves the room [18:27:16] starfish below sponge doesn't look spiky enough for Hippasteria [18:27:45] oh yes bigger one is Hippasteria-ish [18:28:17] can we ZOOM on the star? [18:28:22] Wouldn't those be embryos on the shrimp, given they are being held by the pleopods? [18:28:24] A NON-Hippasteria.. thansk! [18:28:25] LAT : 53.293377 , LON : -169.776168 , DEPTH : 775.8764 m, TEMP : 3.47209 C, SAL : 34.12824 PSU, DO : 0.92097 mg/l, TURBIDITY : 0.9341 FTU [18:29:09] Hippasteria have spines.. this one does not.. more like Ceramaster maybe [18:29:19] The eggs are produced in gametes in the thorax, and once fertilized the female holds them with pleopods (abdominal limbs) [18:30:04] I meant "gonads", not "gametes"! Can't make that kind of an error with a reproductive specialist in the hot seat. [18:31:19] Hah, that's okay Scott, sorry we couldn't get a good shot of where they were, she was certainly packed! [18:31:35] They were definitely on the pleopods [18:31:45] Ceramaster are sponge predators! ha ha! sorry guys!! [18:32:05] THIS IS PRIMNOA [18:32:13] For me [18:32:23] Pretty confident from freeze frames of fish tightly hugging the coral that it is a Carapid pearlfish, similar to genera Synderidia and Pyramodon. Both genera are supposedly 'free-living', i.e., not commensal with an invertebrate. Image of that fish coiled within the coral should be a highlight photo. My best guess from head shape, eye, and presence of clear fan-like pectoral fins is genus Pyramadon. Two species are known from off Japan. [18:32:25] The sponge looks more like a Heterochone calyx (the one with the crab) [18:32:30] This is Primnoa pacifica for me. [18:32:36] Looks like the thick droopy polyps of a Primnoa. [18:32:48] The straight up from a ceenter? This is not the polyp morphology of a p. pacifica for me.... [18:33:10] I believe it is.

[18:33:59] (I screen shotted [18:34:48] Sponge to the right now is Acanthascus (quite spiky) [18:34:59] If another of those coral-hugging fishes is encountered, might be worth a try to suction sample. It looks very reluctant to move from its companion. [18:36:03] @Rhian I think the last one you should collect. it looks like Primnoa pacifica for me. [18:36:57] emilycrum leaves the room [18:37:06] We have passed it Asako, we can look at others [18:37:13] kennethsulak leaves the room [18:37:45] @Rhian forget the branching pattern you know. [18:37:58] There were too many rows of spikes for P. pacifica for me, looking at my polyp close ups from the fjorrds - maybe a variation though, they have a lot of varaition between colonies. The morphology tooof the whole colony was a little strange. [18:38:02] The body proportions of that fish (in the anemone) look more like a snailfish than what we were seeing before. [18:38:21] @Ken - we do not have the permits for vertebrates I think - I am checking now.

[18:49:24] Uh nice Heterochone calyx :) [18:49:39] Tina: I like this spiny vase sponge [18:50:03] @Ken - thank you! They look much different when they come up in our trawls! [18:50:52] please shot the yellow single branched one [18:51:12] Looking carefully at that translucent eel-like fish head down within that large anemone. Again, looks like a commensal relationship. The anemone has contracted the tentacles closest to the fish, none actually touching the fish, none extended to encircle and secure it. You would expect the opposite if the anemone were latching onto a fish to eat. [18:51:23] no never Paragorgia. [18:51:38] Tina: I think bamboo right [18:51:50] Amazing landscape. Must come back and sampling these communities more intensively some day. Could probably spend all day here and still find new things to collect. [18:52:01] Is this the last dive? [18:52:11] Anybody? [18:52:13] Tina: I think bamboo right [18:52:22] Tina: Pacifigorgia? [18:52:30] Elaina - yes, I have seen many trawled up off Greenland in Davis Strait. They get battered and come up pretty much gray - without the nice spots. [18:52:44] Steve we should have one more dive this expedition.

[19:10:18] on the anemone [19:11:18] it's using its suction cup to hold position [19:12:50] @Steve, we certainly could - we have filled two of 4 boxes, and are not even half way - do we think that would be a good collection?

[19:14:59] @Asako? [19:15:05] I believe it's not pacifica. [19:15:34] collecion or no? We have to respond fairly quickly to that if you want collections [19:15:39] Looks much more 'puffy' than pacifica to me. Haven't seen wingi [19:15:53] we did collect this before. close up? [19:16:15] If possible to collect a piece, yes! [19:16:35] @Asako - see message from Steve earlier on Pacifigorgia....not this coral, one from earlier.... [19:16:44] Juvenile fishes? [19:17:11] nursery habitat! [19:17:15] this is not pacifigorgia [19:17:36] @Rhian we collect this before. right? [19:17:43] @asako, you need to read up to Steve's comment on Pacifigorgia..... [19:17:47] @Asako we were asking if you want to collect the previous golden-yellow coral that we called Pacificgorgia . [19:18:18] @Steven single stalked? yes [19:18:25] yes, that one [19:18:29] LAT : 53.29318 , LON : -169.776553 , DEPTH : 751.8334 m, TEMP : 3.37176 C, SAL : 34.16508 PSU, DO : 0.85501 mg/l, TURBIDITY : 0.9402 FTU [19:18:35] TIna also think we should collect the one. [19:18:38] gorgeous shot! [19:19:04] Wow so cool! [19:19:44] @Steve it could be kind of Alaskagorgia more than Pacifigorgia.

I got lots of really good frame grabs. That fish is a stumper. Never have seen a totally white cusk-eel before. No prominent pectoral fin spines either. [19:25:15] the link is for the Alaskagorgia [19:26:06] collect? [19:26:13] jenniferaschoff leaves the room: Replaced by new connection [19:26:14] @Rhian: I heard you say "Paragorgiid" for this one. I think you mean Paramuriceid. [19:26:28] emilycrum leaves the room [19:26:51] Thank you Scott , I asked earlier if paragorgid was a term...no one answered....:) [19:27:03] If this is Alaskagorgia, its current incertae sedis (no family given) [19:27:15] I only know one specimen of Paramuricea from this region in the Smithsonian [19:27:52] @Rhian: Sorry. I was booted out of chat erlier and too busy here to log back in, but am following. [19:27:54] Are we calling it Alaskagorgia or Pacifigorgia? [19:27:57] ChristinaConrath leaves the room [19:28:09] @Asako your call [19:28:28] A few minutes back, tightly puckered red-orange anemone with that same 'pearlfish' sitting upon it. Again - apparent commensal relationship. That fish would have been collectable with suction - worth a try for such an unknown species that is sitting vulnerable to capture.

Could be Alaskagorgia or Cryogorgia... [19:29:05] Plexaurids are out and paramuricids are in - thanks! [19:29:11] its not Cryogorgia I believe Scott. [19:29:18] if no one can decide, Unidentified Malacalcyonacea is the lowest level [19:30:43] I'll put that down - when it comes up I can look in the ID books and see if I can get it further later. [19:31:45] jenniferaschoff leaves the room [19:32:07] oooo! Did they get the oph with the coral? nice! [19:32:27] @Rhian we should call Alaskagorgia [19:32:29] Not sure, didn't spot it initially.... [19:32:46] Found a potential new species from one of the associate brittle stars off the Shakedown cruise corals!!

As someone noted, the translucent fish associated with that puckered anemone is not a carapid, but a liparid. Good close-up. For positive genus and species ID, would be nice to suction and preserve. [19:34:47] I agree with Asako: label it Alaskagorgia [19:35:29] Okay, we can change the label when it come sup to Alaskagorgia [19:35:42] Snailfish body shape and head match Paraliparis, reddish color matches genus Careproctus. [19:37:03] shortspine thronyhead [19:37:25] thanks! [19:37:36] Not sure it has been said, but obviously there is a lot of food in the water column to support this high density of suspension/filter feeders. [19:37:50] Polyps pointing downwards on coral to right! [19:38:11] calyptrophora, likely. large basal spines visible [19:38:16] What is white primnoid coral to right of fish?

[19:40:10] kennethsulak leaves the room [19:40:24] I could see typical two long spines on that coral. [19:40:28] Could also be Paracalyptrophora which is known for downward polyps but the Calyptrophora clade wyvillei has all polyps downwards too [19:40:40] jenniferaschoff leaves the room [19:40:47] Arthrogorgia also have downward polyps and has two spines [19:41:31] shot to the right of a Henricia inside a ponge!

However there is not alot of comparative molecular phylogenetics for this genus. Only a handful of specimens have ever been sequenced and published. Mostly by Scott and Meredith. [19:56:00] Much of the taxonomy and systmatics is based on morphology only [19:56:33] I'm going to head to lunch quickly, be back in a short bit!

This one is very healthy looking so I would say probably not brooding [20:50:10] Thanks [20:51:21] My experience diving has been that this species is pretty bold.
