[14:40:16] they are wondering if they are "Tubeworms?" [14:40:49] I don't see tubes, but they could be worms - polychaetes? [14:41:26] I haven't had a good look, but they could also be the arms of brittle stars that are just under the sediment surface [14:41:27] Any fish people watching -- are the big round burrows tilefish burrows? [14:41:42] about a minute ago [14:43:21] I think tilefish burrows are vertical funnel shaped holes made in the mud. These look like they are dug horizontally into the rock, like lobster burrows.

[14:44:33] Thank you both for answering and giving a shout out! [14:44:45] @bradleystevens not sure - also not sure if they are putting out one arm [14:45:23] @Brad: I think there may be multiple arms spaced out over a distance, such that seeing 5 arms waving is not 5 ophiuroids but one. My guess, anyhow. [14:45:27] there are so many arms they could have multiple extended? [14:45:55] @brad: at least, that is what I have seen in other situations.

Or the ones whose branches fork (which we were calling sponges)? [15:20:08] Not the stringy hydroids. What I mean are the thin branching with bifurcate tips. Haven't seen a good cu though. [15:23:41] @John Interesting - I haven't got enough experience yet to be able to ID many deep water bryozoan species by growth pattern.

It's one of my pet peeves. Especially since, in the US at least, there are no bryozoologists that can take grad students. It's a lot of self-teaching [15:37:44] I'll be glad once I can get a longer stay at the Smithsonian MSC to ID more stuff [15:39:00] LAT : 38.123219 , LON : -73.847942 , DEPTH : 657.1835 m, TEMP : 4.96052 C, SAL : 35.00575 PSU, DO : 7.65929 mg/l [15:39:04] Are these the bryozoans here? The forked tip ones? [15:39:44] oh, are these the carnivourous sponges? [15:40:02] @Amy: that is what I am trying to determine! [15:40:04] @Scott I think they are bryozoans. I saw some lophophores out [15:40:12] @megan: thanks! [15:40:42] Thanks! trying to read and narrate at the same time. [15:41:23] @Scott welcome! They have a very cool branching pattern. It's like most of the colonies we just saw were starting new branches so they looked forked [15:42:04] But maybe they just flare out at the branch tips [15:42:59] @Megan: we've been seeing these forked branchers regularly this week, so it isn't just this patch. We thought they were cladorhizids. [15:43:38] @Amy: I am going to have to leave you in a few minutes for a meeting. [15:43:58] okay, thanks for calling in @scottfrance!

Have we collected any? I would of course be interested in that if possible. Colatooecia mentioned by @John has not been found this far north, so it's either a new record or a different species [15:47:01] Or if there's some coral or sponge collection that has the bryo on it so we get at least a two-fer [15:47:46] @meganmcculler we will see what we can do! [15:48:13] Do you think suction sampler? Probably too small for manipulator arm? [15:49:01] LAT : 38.12319 , LON : -73.847964 , DEPTH : 649.7037 m, TEMP : 4.95624 C, SAL : 35.00736 PSU, DO : 7.66923 mg/l [15:49:38] @Amy ummm...some of them look fairly large? Branching species like this often have rhizoids to attach them to the substrate, so I'm not sure the suction sampler would work [15:50:15] @Amy I would say if there are any on a sponge or something else we want to collect that might be a good way to go [15:50:29] I'm off the phone now. It's interesting to see so many pairs of grasping crabs at this time of year. Some crabs like to find "safe" locations for mating, and clinging to the rock walls may help them stay away from other crabs. [15:50:56] Gotta go. I should be back in 30 minutes [15:50:58] taraluke leaves the room [15:51:08] @meganmcculler Okay, good to know. Our pilots are amazing so I'm sure we can figure something out although I'm not sure how easy it is going to be to sample here in general due to the current. [15:51:09] Golden and scarlet king crabs like to hang out on large vase sponges when mating on N. Pacific sea mounts [15:52:47] @Amy Sounds good, thanks! That's what I figured - if there wasn't much current we could do like a few dives ago, cut with manipulator arm then suction [15:52:49] Little flicking appendages are the antennules that have chemosensory cells on them - it is the crabs "nose". Probably detecting lots of pheromone "perfume" emanating from the female.
