[15:14:12] Maybe explaination for burrows is infaunal inverts. Macroinvertebrates. Many fossorial amphipods. Les saw the Cumacean. I missed it. Not sure about sizes of burrows. Polychaetes too. I have look at preserved deep sea sediments separated by 500 micron sieves.

[15:49:25] @tom ooh not sure. good question. are the larvae for this genus known? [15:50:27] i don't think these are mysids, are they? [15:51:11] I think that one is a decapod. Not the same as previosu. [15:51:24] @Andrea I took larval fish class and we looked at osteology [15:51:35] That one didn't look like a mysid to me, but don't have another idea for it either [15:51:48] LAT : 34.775007 , LON : -75.345486 , DEPTH : 1586.3601 m, TEMP : 3.92425 C, SAL : 34.96033 PSU, DO : 7.99478 mg/l [15:51:59] previous [15:52:04] yes, that was not a mysid [15:52:08] Mysid with extended pleural plates. I think shrimp [15:52:20] halosaur [15:52:25] @tom of bathypterois? my ichthyology knowledge is because of fish larvae…i identified about 20k of them for my MS [15:52:33] yes this is a halosaur [15:52:40] can you zoom head, i think this is Haolsauropsis [15:53:10] Why are the ventral scales so large in that halosaur? [15:54:03] josephhoyt leaves the room [15:54:10] @Andrea. Wow. I had Dr. Olney for a class [15:54:19] some species have ll scales bigger than others [15:55:15] YEs, pretty sure halosaur is Haolsauropsis macrochir [15:56:08] jillbourque leaves the room [15:56:23] LAT : 34.775026 , LON : -75.345824 , DEPTH : 1580.9116 m, TEMP : 3.90807 C, SAL : 34.95958 PSU, DO : 7.99033 mg/l [15:57:59] Third maxillipeds with golden setal brushes.

[16:01:53] stevenauscavitch leaves the room [16:02:17] Hey Kasey, as a heads up, we will be calling in in about 10 minutes. [16:02:23] that was a cusk eel [16:02:39] ok great! [16:03:24] Collect one and then do gut study. [16:03:33] amazing behavioral observation! [16:03:48] Crab note///mud on carapace and 1st segment of walking legs...has been in a burrow. [16:04:36] May be periphyton on outside of arms so it is eating these. [16:04:50] snacking on the arms. sort-of like hot wings. [16:06:05] Thank you!

It is taking the protozoan sessile organism off of them. [16:07:13] I think [16:08:27] I changed my hypothesis. More like eating corn on the cob. [16:09:15] cranchy... [16:09:47] ophiuroid central disk contains the "soft bits" stomach, glands, gonads if developed. [16:10:37] just ate bits of the arm [16:10:48] we got highlight video [16:11:17] oh i take it back, its still just grooming stuff off the arm [16:11:28] LAT : 34.775039 , LON : -75.345687 , DEPTH : 1577.9456 m, TEMP : 3.87684 C, SAL : 34.96066 PSU, DO : 7.98618 mg/l [16:13:06] Mandibles are not working on arms.

[16:17:28] gill bailer, forget scientific name. [16:18:58] Hi Kasey, we may not call in to avoid feedback since the noise is so loud in the auditorium. I have one question from the audience that wants to know how big the crab is [16:19:19] scathognithite. Gee [16:19:34] scathognathite [16:20:11] Sounds good Joe [16:20:21] you can send them here [16:20:46] thanks. Another question: what is the policy on specimen collection and how is it done? [16:21:01] The mandibles did not work until it got to body disk. [16:21:25] LAT : 34.77503 , LON : -75.345727 , DEPTH : 1577.9216 m, TEMP : 3.76639 C, SAL : 34.95367 PSU, DO : 8.022 mg/l [16:23:02] Uses mandibular palp to lift separated disk to crush it with mandibular molars. Neat. [16:23:17] When I was grad student I studied scavenging amphipods very closely. Their mandibles had a distal cutting edge and a proximal grinding surface. At least there it looked like I could detect cutting edges at the tips of the mandibles. [16:24:07] @Scott yes [16:24:46] Henricia type... [16:26:26] LAT : 34.775052 , LON : -75.345858 , DEPTH : 1574.4426 m, TEMP : 3.74045 C, SAL : 34.95497 PSU, DO : 8.02567 mg/l [16:28:02] @Leslie: I'm not sure if you said it, but we also want to be sure the samples collected have scientific relevance and importance, and for that we look for consensus among the scientists in the chatroom. [16:28:18] a question from the audience at the NC aquarium: How fast can a sea star typically move and what is their range? Do you see similar things everywhere, or are these regionally specific species. [16:28:38] great answer on the collections policies! Thanks! [16:28:49] @scott - will add [16:31:15] regenerated arm! very cool [16:31:29] LAT : 34.775082 , LON : -75.345984 , DEPTH : 1568.6179 m, TEMP : 3.7373 C, SAL : 34.95518 PSU, DO : 8.02757 mg/l [16:35:24] This is great!

[16:36:27] LAT : 34.774947 , LON : -75.346061 , DEPTH : 1567.8058 m, TEMP : 3.72648 C, SAL : 34.9542 PSU, DO : 8.01963 mg/l [16:36:37] This is the one I suggested might be the sea pen Distichoptilum... [16:38:07] zachproux leaves the room [16:38:20] Another question from the audience: How much does the presence of the vehicle itself influence the behavior that is being observed? [16:38:29] andrewshuler leaves the room [16:39:42] @ joe - it depends on the organism. Sometimes organisms are attracted to the light , sometimes organisms are scared away. Some of the organisms we see (like corals) don't have eyes and don't notice we are there at all [16:41:28] LAT : 34.77504 , LON : -75.346301 , DEPTH : 1565.969 m, TEMP : 3.72614 C, SAL : 34.95276 PSU, DO : 8.02917 mg/l [16:44:07] Thanks Team, We will take a break here at the aquarium and be back to ask more questions from the crowd around 2pm!

Rest assured there is an ID that will be part of the metadata. [16:48:53] Looks molluscan to me... [16:50:32] danielwagner leaves the room [16:51:15] @Leslie: is this the ridge we looked at on the dive call last night? What happened to the current-swept rocky ridge?

[16:52:31] crab juvenile [16:52:46] Looks like lithoid. Agree [16:53:03] Carapace with spines. [16:53:23] That's so cool @Tom!

If not, it might have been a pelagic nemertean. [16:57:42] @Mike: I could see the parapodia and chaetae [16:57:53] My resolution was not good enough to be sure. [16:58:10] @Mike: didn't look like those pelagic nemerteans [16:58:18] OK Scott. ploychaet.

[18:00:26] mysid staying downcurrent to sea pen. [18:00:33] Sorry, I meant sea pen Anthoptilum [18:00:42] Brittle star is probably Asteronyx, or a relative [18:01:05] Maybe Anthoptilum grandiflorum [18:01:17] What is the deepest that the Okeanos can explore?

[18:02:53] The rachis curls... [18:03:02] halosaur [18:03:36] @Tom, not sure what the mysid is doing, but we have seen it a lot, and somewhere I have a specimen because it followed a coral we were collecting into the biobox. Always hovering around the octocorals. [18:05:44] From the NC aquarium: What happens with all the data that is collected from the Ship?

There was a second lower mound to the left that made me think terebellid. [18:14:00] the two grooves along the side of the pellets must also be distinctive... and I know that when we fed pink particles to a local mudflat terebellid the particles all were arranged in a nice little line along the pellet side. [18:15:19] I think Funiculina is a good guess for thta last one [18:15:37] @Les: yes, good observation.
