[00:02:04] The rough texture also suggest possible Paracis-like taxon. [00:02:17] Paracis (and others) have very thick sclerites [00:03:26] LAT :-2.72906, LON : -175.12807, DEPTH : 1954.0662m, TEMP : 2.27550C, SAL : 34.63820 PSU, DO : 3.47971 mg/L [00:03:53] mashkoormalik leaves the room [00:08:12] White morph Paragorgia ? with zoanthids [00:08:26] LAT :-2.72904, LON : -175.12811, DEPTH : 1946.3552m, TEMP : 2.27363C, SAL : 34.64027 PSU, DO : 3.39928 mg/L [00:08:28] Paragorgia comes in red, pink and white [00:08:45] could be Sibogagorgia? [00:09:16] Just for perspective, how many deep sea octocoral species are there? (There are ~~450 scleractinians on shallow tropical reefs) [00:09:21] Could be. I should have written the more general paragorgiid. [00:09:23] ophiocantha like oph at the base....the same asteroschemid like oph among the branches [00:09:29] Hyalonema? [00:10:02] I think it's in that family, but Chris has been calling it a different genus than Hyalonema. Could be in the family Hyalonematidae. [00:11:00] Another Euplectellidae, I think. [00:11:09] @randirotjan: I's say on the order of 300 species of dee-sea octocorals. [00:11:51] I should know better but my memory fails me and would have to check on some papers.

The tubular ones with a sieve plate at the top are euplectellids. [00:15:36] @randirotjan: You could start with our paper in Adv Mar Biol on deep-water octocorals (http://www.sciencedirect.com/science/article/pii/B9780123855299000020), which includes the sentence: "By the time of Kukenthal’s (1924) volume summarizing the state of knowledge of the gorgonian octocorals, 226 species had been discovered living in deep water, representing 29% of the 781 species in the monograph." Give me your email nd I'll send you a PDF. [00:16:10] This stalked vase is not a euplectellid. Unfortunately, I don't know what it IS :-( [00:17:58] @Scott - sent to you in separate chat too, but rrotjan@bu.edu [00:18:21] @scott would you mind sending a copy to me as well? luket@stockton.edu ?

[00:33:23] @Scott, was a very unusual colony, tall as Steve says, but mostly straight up [00:33:27] @Steve: Tina requested if we could find black coral we could see twice at the beggning of the dive.

[00:34:16] polyps had a funny way of contracting as well, pulling tentacles in deeply, before column contracted a bit. polyp also white suggesting heavy scale density [00:35:58] @Scott: She mentioned Heteropathes cf. americana. I think we did not seen such colony before. [00:36:14] there was also a smaller bamboo early in the dive that was branched at internodes. We may not see it again but if we do then it would be good to pick it up [00:37:06] this primnoid could be a Candidella [00:37:15] Candidella?

[00:39:21] and the tissue has overgrown something [00:39:36] Yup - interesting - new polyps budding there. [00:40:09] @Les: classic "long ones?" [00:40:13] *bones [00:40:39] Beauteous. [00:40:51] was thinking that but the polyps are more devoid of sclerites, so probably B! [00:41:09] @Les: Dang. I was going with C1 clade! [00:41:45] must be a couple of meters tall, and such a small holdfast! [00:42:30] I think C1 has long intertentacular needles, at least 4 if not more [00:42:37] Perhaps low current strength, less "wobbling" at early growth stages, so small holdfast. [00:43:02] @Les: confession: I'm cooking dinner, so wasn't looking closely at the polyps! I am ashamed.

Roadside Assistance follies followed, the end result of which was spending 5 hours on the side of the road and eventually abandoning the vehicle. So, after getting up before the crack of dawn for the cruise, I didn't get home until after 1 am. I'm just getting my bearings! [00:48:21] eek. You've definitely had a rough day, Scott!

[00:49:46] haha @Scott... love those field trips with university vehicles.... I usually took my own car for that reason... [00:50:17] The sponge is another hexactinellid; I think it's a hyalonematidae. [00:50:48] and an I magnispiralis [00:51:22] Seastar "Henricia" like? [00:51:43] I should check before guessing, but this is how CK taught me! ;-) [00:52:15] @Scott: I feel very sorry to hear your hard day during our fantastic dive..

[00:57:07] like a funky branched parantipathes [00:57:13] Doh [00:57:47] You got me on the "funky," though, Tim. [00:58:15] thick branches...in a funky branching pattern..

[00:59:02] Hard to tell without detailed look at the spination of the skeleton. [00:59:46] Note that these cylindrical spiky sponges have ben very common. [00:59:52] Been. [01:00:09] not a bad way to spend the evening though, hey @Shirley [01:00:15] metallogorgia? [01:00:19] Finally a Metallogorgia! [01:00:21] metallogorgia! [01:00:29] No, especially when my husband is on the Okeanos!! [01:00:43] Ophiocreas oedipus oph, maybe [01:00:52] fish! [01:00:56] Perhaps a Metallogorgia juvenile next to it. [01:01:09] oh i guess not…. [01:01:29] But I see no oph on the smaller one... That is too unusual [01:01:35] the one next to it should be collected. Its very different [01:01:53] That one on left is not M. melanotrichos! [01:02:05] If we have collection time/.space, I say collect! [01:02:10] so same sp or no? [01:02:18] I am back awake [01:02:36] If it were M. melanotrichos, 100% of the time we see an oph, even on the juvenile colonies. [01:02:40] it is good timing for the collection. collect from me too! [01:02:52] i think they are different species [01:02:53] advise early if we are collecting the ship is needing to be stopped [01:02:58] The branches themselves also look different, I think. Lets get a close-up [01:03:32] collect....the adult and the potential juvenile?

[01:05:06] agree with @Scott, I think the little one is something completely different, but only one way to tell... maybe this is what a juvenile looks like with no ophi [01:05:14] fishy people, what is it? [01:05:36] some type of Hake? [01:05:43] lepidion [01:05:49] Moridae [01:05:52] I think the metallogorgia + other is worth a second look [01:05:57] yep, type of hake [01:05:59] agreed. although I feel like we saw something somewhat similar on the NE Seamounts [01:06:09] agreed- would like a second look. [01:06:37] yes, it is a Lepidion sp. [01:06:38] Did you see the oph in the Metallogorgia? the upper arms were (very) highly swollen. [01:07:24] @Tim, that is because they were reproductive. That group has the gonads in the arms rather than in the disk [01:08:10] My impression of that "juvenile" was that the branchlets were too curved upward for M. melanotrichos. [01:08:24] Lets have a look (I know we are going there) [01:08:32] LAT :-2.72984, LON : -175.12690, DEPTH : 1859.6787m, TEMP : 2.35394C, SAL : 34.63309 PSU, DO : 3.45984 mg/L [01:08:39] i.e. that was not a command to science team. [01:09:01] nearly there [01:10:24] what is the 3rd short stalk between the 2? [01:10:43] @Les, yes I was calling out that the gonads are loaded ... I don't think we have seen that the majority of the time... [01:10:57] Branches do not come out at same level on sides of axis: this is not Metallogorgia. [01:11:03] Must be a Chrysogorgia. [01:11:17] do not think they are same. size of polyps is different [01:11:32] i.e. branches alternate instead of opposite [01:11:54] "Must be a Chrysogorgia" or some other chrysogorgiid. [01:12:12] We can't collect it? [01:13:13] we could... its certainly rare.... [01:13:19] Have a good framegrab of the ophiuroid, but of course would love the sample. [01:13:31] It is also the only one we've seen in 2 expeditions [01:13:33] LAT :-2.72989, LON : -175.12693, DEPTH : 1860.8588m, TEMP : 2.37668C, SAL : 34.63367 PSU, DO : 3.40129 mg/L [01:13:47] OK. I'm standing down to let others weigh in. [01:13:52] smaller one here is a chrysogorgid no? [01:13:59] Having not seen 2 individuals it might not be prudent to collect this one [01:14:41] small yellow crinoid near the lowest barnches [01:15:16] Smaller one is definitely a chrysogorgiid (but so to is Metallogorgia). I just wanted to be sure it wasn't lumped in as a Metallogorgia juvenile, whcih was the first thought. [01:15:25] taylorheyl leaves the room [01:16:06] @scott stem was stright [01:16:11] I think at least the smaller one should be collected. It is odd but I am betting its a juvenile Metallogorgia based on the branching. [01:16:19] @Steve: ok, understood. But I think that is the first time I've heard that rationale (which doesn't mean I disagree with it) [01:16:52] Stem was straight and the branches at the terminal end are dichotomous. It has no brittle star which is the only time we have even seen that.

Internodal. And probably with "scaly" sclerites based on smoothness of the polyps. But the polyps were interestingly thin. [01:26:07] this place keeps throwing weird things at us...

But I completely agree we don't want to knock down a living colony to get at the thickest part of the axis. [20:02:16] the large crab we saw on the bamboo, identified on EX1504 as "Galatheoidea long arms spiny" - on a sponge and dead coral branches.
