That species is known only to about 113 meters. The hogfish that we saw may have been an undescribed species, but don't take that as a firm statement. [00:04:39] Hi Everyone.

[00:08:03] although at this shallow depth the affinities are a little tough to tell as the fauna has become rather sparse.

Velatida. But I was also hoping Chris was still online.. [00:11:34] Chrionema species, Percophidae. Similar to C. chryseres, but may be a different species. [00:11:42] I think the seastar is a Paranepanthia sp (Asterinidae). You can see a picture of it in the HURL Animal Guide. I was just waiting for Chris Mah to call in. [00:14:54] I will definitely defer to you Chris. Diplopteraster is typically deeper than 800m...

The people that I work with who would know are at sea now, collecting specimens of snappers. The species occurs down to 300 meters and we see them at the depths where we now are, so I don't think this is exceptionally deep. This species occurs throughout Oceania, except for the Hawaiian Islands where it is replaced by a congener. [01:08:10] That is good, thanks.

[01:24:05] it is hard to tell to genus, you have to bleach it first [01:24:58] that's as close as I can come with the guide.

A two-fer [19:56:30] what is the concensus on shore for collection [19:57:00] it may be difficult to get both the anemone and the oph. they are not easy to reach for the arm [19:57:09] sounds like a good one to collect (get associates with it, too), but I'm not a coral biologist [19:57:52] LAT :-5.63233, LON : -173.83791, DEPTH : 1841.3077m, TEMP : 2.37307C, SAL : 34.62919 PSU, DO : 3.77277 mg/L [19:59:03] Amy should be here...

[20:06:22] test [20:06:46] hi tim [20:06:47] we will look at the CORA [20:06:50] Morphology seems most similar to what is referred to as Paragorgia coralloides, but it is hard to tell from images [20:07:24] looking at red Paragorgia with 1 ring anemone associate and several ophiuroids (red, blending very well with coral)- looked to be asteroschemid ophiuroids [20:07:54] LAT :-5.63235, LON : -173.83788, DEPTH : 1841.8520m, TEMP : 2.37397C, SAL : 34.63047 PSU, DO : 3.75440 mg/L [20:07:55] arms spread with star wraps on adjacent branches [20:10:51] beautiful sample!

[20:20:34] great shot of the chirostylid. Thank you! [20:20:39] any way to guess ages on some of these? [20:21:04] @Randi- have to collect [20:21:17] assume you meant the coral and not the squat lobster... [20:21:28] yes coral. thanks Tim!

[20:26:08] nope no rocks [20:26:14] @Randi - I forwarded your request to Allan Andrews in the same research group as me. He has worked on coral ages and provided some estimates yesterday. We'll see if he can help. [20:27:12] @Bruce - thanks! [20:27:45] Iridogorgia- no apparent associates [20:27:56] LAT :-5.63238, LON : -173.83798, DEPTH : 1831.8288m, TEMP : 2.35586C, SAL : 34.63157 PSU, DO : 3.77318 mg/L [20:30:33] nicolemorgan leaves the room [20:32:08] Les! check the colony now!

[20:33:03] That Iridogorgia is a young one of the new Rhodaniridogorgia we have from Amy Baco_Taylor's Necker Ridge collection [20:34:10] jaymesawbrey leaves the room [20:35:08] looking for a little context here - are there tons of new small benthic recruits in the background? (sorry - new to this) [20:36:14] This bamboo looks like it is probably in the D! or D2 clade, which include Keratoisis and its relatives. Can't tell which one though but it has the open branching pattern of K. grayi. [20:37:57] LAT :-5.63225, LON : -173.83796, DEPTH : 1825.9047m, TEMP : 2.36573C, SAL : 34.63069 PSU, DO : 3.76576 mg/L [20:38:42] A lot of hard bottom substrate...a lot of attached fauna. [20:39:09] jaymesawbrey leaves the room [20:39:58] Nice ridge line. Good habitat for sponges and corals, when currents are good to provide food. [20:40:07] O2 levels?

[20:43:36] @les: agree with B1 [20:43:51] go back to the coralliid please [20:44:38] @Abby, thanks, was beginning to think maybe C1, but not quite right, even though long bones... [20:45:20] We imaged a couple of the corallids earlier. If we come across another on the way we can take another look [20:45:58] beautiful!!! [20:46:18] Iridogorgia new species in the back, and I magnispiralis in the front [20:47:12] Interesting that when D2 turned away from the ridge the sessile fauna became very sparse [20:47:24] In order to know who the corals are, close shots of the branching and polyps will be needed. There seem to be a lot of unusual things here. [20:47:43] @Erik, what were you thinking doesn't look like mutualism. the associates on the dead bamboo skeleton?

[20:49:27] what a busy area! [20:49:36] adriennecopeland leaves the room [20:49:38] All this is very different from what we saw in A. Samoa! [20:49:53] busy for corals and busy for Seascribe... [20:49:56] Anthomastus [20:50:46] flytrap anemone (hormothoid) [20:50:58] Venus fly trap anemone on bare coral skeleton- 3rd observation [20:52:50] probably Hemicorallium [20:52:58] LAT :-5.63224, LON : -173.83802, DEPTH : 1816.3260m, TEMP : 2.41881C, SAL : 34.62432 PSU, DO : 3.73731 mg/L [20:53:27] great shot [20:54:00] thanks [20:54:32] there is that little mysid hovering around the colony. we have seen that all over the place.... [20:55:05] black coral mimicking Metallogorgia.... [20:55:07] umbellapathes? [20:55:49] anemone on a crab on a black coral?

[21:01:41] briankennedy leaves the room [21:01:52] very long armed crinoid [21:02:34] are they Pleurogorgia?

[21:05:06] we think it is Anthomastus [21:05:23] Hi Tina! [21:05:27] I think this is Anthomastus, [21:05:40] I think so too... [21:05:42] craigrussell leaves the room [21:05:43] we collected one similar in the GoMx in Desoto Canyon~~ [21:06:06] cutthroat [21:06:18] hi everybody [21:06:30] video breaking up....

[21:22:27] Anthomastus tahinoides [21:22:48] Nice one @Tina! [21:23:08] jaymesawbrey leaves the room [21:23:10] great Tina! [21:23:12] mmm, cool! [21:23:25] tahinodus [21:23:29] sorry [21:24:30] An Eknomisis with no color in the tissue, or maybe the tissue is mostly gone [21:25:27] @les, it may be good to ask tahinodus for genetic [21:26:58] Excellent idea @Tina.... did you get that @Steve and @Amanda? I recommend also we collect that brown Anthomastus if possible. [21:26:58] Saw a video of the Synaphobranchus posted on Facebook. The dorsal-fin origin was far behind the anal-fin origin, which narrows the identification to either Synaphobranchus oregoni or (most likely) S. brevidorsalis. [21:28:00] @les, apparently it has to go to another clade [21:28:50] is that because of the siphonozooids on the column? [21:29:30] Fish in center [21:30:13] falling seastars?! [21:30:20] light sensitive? [21:30:25] went into a hole. was probably and eel [21:33:54]
