[15:13:03] Thanks Scott,will resend. We have seen a possibly carniverous tunicate on the dive and there was interest in sampling it [15:13:53] I thought maybe that was a brachiopod? [15:14:07] "clam" might be a brachiopod [15:14:12] I just tuned in so had not seen it.

[15:14:42] Unable to see a stalk from this angle but I bet brachiopod [15:14:59] @Mike: can you paste today's SeaTube link in chatroom? [15:15:02] @Scott agreed! [15:15:21] Sanamyan, K.

[15:16:33] In this paper there is a description of Megalodicopia species from deep (>4000 m) South Atlantic. It is a different species cause the size and the aparent lack of stalk.

Would that be something you're interested in or is there a desire for a sample from this particular area? [15:33:36] I think those are baby pycnogonids?? [15:33:43] like the eggs have hatched?? [15:33:49] baby pycnogonids on daddy pycnogonid?

[15:36:22] Awesome! [15:36:35] Verification for sure that those are offspring. [15:37:26] Personally I don't think it is worth trying to follow the young ones drifting off. [15:37:38] They will simply drift away. [15:37:58] It may be that we have just caught this individual at the time that the embryos are hatchjing [15:38:41] Oh Wow!!! True Highlight!!!

[15:43:12] @Kim Now that pycno distraction is over... yes!!! I have a list of all the bryozoan lots collected from previous expeditions and looked at a few of them last time I visited the MSC, but I would love to see rubble and/or sediment [15:44:16] LAT : 30.760194 , LON : -78.746189 , DEPTH : 827.8034 m, TEMP : 8.22122 C, SAL : 35.1211 PSU, DO : 5.17206 mg/l [15:44:33] Sounds good. I've been advocating for sediment sampling, but since we collected some with other samples..it's hard to jusitfy more sediment sampling when it's likely all the same material [15:46:52] If we suck up another sample, I'll ask them to try to scoop up more material [15:48:16] Sediment will probably just include colony remnants or possibly small free-living colonies (e.g. Cupuladria) but is still useful, especially when so few colonies are big enough to be sampled by other means. From museum collections of trawled/dredged coral and bivalve rubble I've found a number of species [15:48:49] lazers on actopod?

So if we collect additional sediments/rubble with other samples, should they be preserved in ETOH? For the last sediments that came up I had rinsed in fresh water and dried it before storing it, but if you're interested in the colonies associated with the sediments/rubble then preserving these would be needed? [15:53:15] I think the octopod was a small Pteroctopus tetracirrhus.

[15:56:47] I would answer "No, crinoids are not normally that active." I agree with what Steph answered. More typically they remain in one position catching food in the water and move only when they need to.
