[14:26:53] Nice, wouldnt be interesting to collect some of that microbial mat. [14:28:08] Dr. Hannisak says for sure not a cyanobacteria for the depth. But it is the most abundant visible organism here. [14:28:11] Looks like a primnoid octocoral [14:28:33] Note the relative stiffness of the skeleton [14:29:25] But I could not make out any scales typical of primnoid polyps. [14:29:58] What is that attached to the coral? [14:30:05] The blob wasn't in clear enough focus, but could have been a withdrawn sea cucmber or a tunicate [14:30:30] I have a small screen- looked more like a tunicate. [14:30:34] Hexactinellid [14:30:41] other whote sponges [14:30:54] That matty stuff is likely old mucus from a mollusc or worm or cerianthid anemone that has caught up sediments. [14:30:58] LAT : 28.431977 , LON : -79.04616 , DEPTH : 858.1931 m, TEMP : 5.87526 C, SAL : 35.04306 PSU, DO : 7.15747 mg/l [14:31:19] Yes, Anthomastus at base of isidid [14:31:31] Isidid = bamboo coral [14:31:44] There are several of the white "plate" sponges with fringe. [14:32:14] I meant the mucus is a feeding net that captures sediments... It is "old" in the sense that it has been abandoned by its maker. [14:32:36] I take back the isidid ID. Can we get closer look at white coral? [14:32:48] Not exactly sure what they are: most likely glass (or hexactinellid) sponges, but could also be demosponges. There are a lot of "look-alikes"--unable to distinguish without a spicule prep (but I''m not suggesting that we collect). [14:33:00] No worries! [14:33:08] Few sponges here [14:33:24] On closer look it may have been something like a Swiftia, not a bamboo coral. [14:33:56] Agree Steph - I mean related to Swiftia, ew.g. some Plexauridae [14:34:08] Ring anemone [14:34:28] Definitely not a bamboo coral, so this was a good look. Thanks. [14:34:36] That was good - we cvan move [14:34:51] Great response time! Thanks team! [14:34:59] Yes - permanent inhabitant of the coral. [14:35:15] Basically the pedal disc forms a ring around the branch [14:35:20] White Hexacts and maybe an Axinellid fan tan in color to the right after [14:35:33] Good question - I don't recall seeing them on dead skel;etons... [14:35:40] That sponge , lets get closer [14:35:56] Yes, it may be a Phakellia! [14:36:00] LAT : 28.431979 , LON : -79.046149 , DEPTH : 856.7796 m, TEMP : 5.90078 C, SAL : 35.04278 PSU, DO : 7.14336 mg/l [14:36:01] Interesting Scott. [14:36:28] Veining is caused by clusters of silica spicule tracts. [14:36:49] And they do tend to face the current. [14:37:02] No need to collect! [14:38:02] From a Ocana et el (2004): "During the last two decades several species of ring sea anemones have been recorded in different areas of the Pacific Ocean, from Japan to New Zealand, on different bottoms and depths, 30-1500. Ring sea anemones are remarkable because of their particular attachment to gorgonians. They show a high degree of morphological transformation, resulting in a considerable differentiation between the pedal disc system and the rest of the body. The ring attachment is unknown in any other actinians that live as epibionths on anthozoan (e.g., Hormathiidae). In addition, RSA may be parasites of their octocorals hosts." https://core.ac.uk/download/pdf/26907920.pdf [14:39:14] actiniarians = sea anemones [14:39:28] Hooray! [14:40:34] On approach the overall colony morphology suggests a D clade isidid, perhaps genus Eknomisis [14:40:46] If it is, then branching should be at internodes. [14:40:59] LAT : 28.432009 , LON : -79.046041 , DEPTH : 853.5594 m, TEMP : 6.00707 C, SAL : 35.04199 PSU, DO : 7.03191 mg/l [14:41:29] Yes, there we are: internodal branching. So I guess Eknomisis for this coral. [14:41:51] dialing [14:45:16] The "mucus" visible around the base of the bamboo coral (and those seen early) all take the form of flattened funnels--broad and open at one end and tapering to a narrow opposite end. I have seen these in this characteristic shape on dives all over the region, but I have never seen an occupant. [14:46:00] LAT : 28.432141 , LON : -79.045966 , DEPTH : 850.6758 m, TEMP : 6.04559 C, SAL : 35.05119 PSU, DO : 6.99406 mg/l [14:47:36] jimmasterson leaves the room: Replaced by new connection [14:47:40] kennethsulak leaves the room [14:48:46] Sympagella nux. Hexactinellid sponge. [14:49:07] Looks like a crustacean inside one of the balls. [14:51:00] LAT : 28.43212 , LON : -79.045927 , DEPTH : 848.9983 m, TEMP : 6.07057 C, SAL : 35.04813 PSU, DO : 6.95964 mg/l [14:51:12] Also, note the little "fuzzy branching trees" all over the the dead coral and hard substrates. They are agglutinating foraminiferans. Their relatives are single-celled members of the plankton that produce a sand-grain-sized calcium carbonate test (shell). These bottom-dwellers glue together fine sediment grains. They are actually among the most abundant organisms on these deep hard substrates. [14:52:58] cristianacastellobranco leaves the room [14:55:03] Looks like hexactinellid--heterotellid. Look for pairs of shrimp inside.

Skate imaged a short time ago probably is the Blackfin Skate, Fenestraja atripinna. A deep-water species known only from a few specimens. Occurs ~~600-900m in Pan-Caribbean to Bahamas region. I have not seen this species previously in subsea images. May be the first such image of a perhaps rare skate. Very few skates have distinctly black dorsal fins, increasing confidence in ID [18:31:21] LAT : 28.429791 , LON : -79.044609 , DEPTH : 837.808 m, TEMP : 6.55497 C, SAL : 35.0626 PSU, DO : 6.43726 mg/l [18:34:31] Demosponge [18:35:06] allencollins leaves the room [18:36:22] LAT : 28.429663 , LON : -79.044635 , DEPTH : 838.357 m, TEMP : 6.54889 C, SAL : 35.06236 PSU, DO : 6.45949 mg/l [18:41:09] many skates are benthic invert feeders (except large deep-sea species are fish feeders). Most have teeth modified into a crushing pavement good for munching molluscs. Prey is detected using extensive array of electrosensors on the underside of the snout and body. When buried prey is detected, excurrent flow is used to blow a pit in the substrate, exposing the prey to be sucked into the mouth. Nice that imagery today captured such a feeding event, probable mollusk prey.

[18:45:14] abigailpratt leaves the room [18:45:33] two of the fringy white plate sponges that we collected, again here [18:45:35] shirleypomponi leaves the room [18:46:05] Steph - the time seems condensed when looking back at the video. I did not note how long ago, but the fairly large gray skate was imaged in a fairly long segment. Grey disc, thin white margin, no obvious color markings, fairly long thin tail as is typical of genus Fenestraja, three prominent rows of spines all along the tail. Two tall black dorsal fins, distinctly separated from one another, black tip of tail (caudal fin). Only skate I saw today - but perhaps I missed another one? [18:46:23] LAT : 28.429643 , LON : -79.044672 , DEPTH : 838.0684 m, TEMP : 6.55402 C, SAL : 35.06278 PSU, DO : 6.45962 mg/l [18:48:01] Hey Ken- there are 2 skates, there was the one with the spines on the tail. and later we saw one i thought was benthobatus. [18:48:21] What is the thin white branching, Kasey might think it could be a Cladorhizid [18:48:32] Interesting dive. Lophelia rubble is good habitat for lots of inverts, but generally rather poor fish habitat. Most fishes using such habitat are sedentary or cryptic sit-and-wait stealth predators [18:50:30] I think this is a hydroid not a Cladorhizid [18:51:23] LAT : 28.429623 , LON : -79.044605 , DEPTH : 837.7096 m, TEMP : 6.58799 C, SAL : 35.0636 PSU, DO : 6.43217 mg/l [18:51:53] I think getting this community is a good idea.

[18:52:55] :yes: [18:54:33] Hmm - I did not see the Benthobatis, but the habitat and depth are right for that rather distinctive fleshy, blob-like genus in which the eyes are so tiny that they are barely noticable. Benthobatis is equipped with notable electric organs ventrally. Probably powerful enough to stun prey. [18:54:57] does bentho have a large tail fin? [18:56:01] Going back to that volutid snail, Jerry Harasewych says it was likely Scaphella.
