So the "connectivity" angle refers to a list of species that were generated 2 or 3 years ago (following the ASPIRE workshop) that represented species people on both sides of the Atlantic were working on and where additional samples could prove useful to a larger dataset, if they cam from new locations (I mean "new" in the sense that species had not been collected there before). You are, of course, spot on that low sample sizes cannot reveal much (anything) about population analyses. The idea is that we would have a limited list of taxa that would qualify for collection even though they are not new species or extended ranges or "characteristic" (the typical things we are looking for in a collection since we are limited to so few). There is more to it than this and I can get you a link to the ASPIRE reports if you are interested. [17:04:02] arbuscula is really descriptive name for these Acanella [17:04:52] Irridiogorgia [17:05:56] @scott, taking into account that you need 30+ sample from same location to test connectivity bw population it is virtually impossible without destructive sampling...

[18:00:35] It's probably not too happy about bumping into the bottom like that [18:00:37] nice gonads! [18:01:06] :) [18:01:36] drats. missed it. too many virtual meetings!

Any idea if this has been collected here? I would be interested in examining some [18:05:08] leswatling leaves the room [18:05:43] yes, we collected a large specimen from Yakutat... [18:06:20] Thanks Les. Just verified the same. [18:06:25] that's the one we call purple plexaurid, looks sort of like a paramuricea but no thornscales [18:07:06] @Les @Scott Thanks. I'll follow up on that later on. [18:07:20] @Steve, I can send you a dry branch if you are interested. The colony I have is 3 feet across....

I'll follow up with you by email to explain what I'm working on. [18:09:06] the term "garden" is interesting - coral/sponge gardens have management implications. Is anyone aware of a/the fomal management deifnition of a garden, perhaps from EU MSFD, NOAA? [18:09:15] @Steve: I can tell you it was a pill to work on the DNA.

[19:09:36] Hah - maybe! [19:09:41] hey we're back :-) [19:10:10] it was a beautiful Beroe that you had on camera when the chat went down. [19:10:23] And before Bob Carney gets mad at me, I mean less biologically interesting from an ROV video perspective! Plenty of cool biology in those sediments, as you have been noting. [19:10:48] lobate ctenophore [19:10:53] @George: an another to welcome you back. Well, not a Beroe this time [19:11:06] Bathocyroe [19:11:29] also abundant in the water column on the way down [19:12:06] iscwatch leaves the room [19:12:12] They are such interesting looking fish! [19:12:29] sorry - phonetically Bath-o-sigh-roe-e [19:12:48] @scott...you are forgiven [19:13:07] Thanks Bob. [19:13:24] Look at all those burrowing critters with no respect for stratigraphy [19:13:37] perfect pronounciation! [19:14:41] Halosaur [19:14:45] Looks like a swollen belly. Pregnant? [19:14:47] maybe [19:14:53] Or way overfed? [19:14:58] well fed? [19:15:03] Nice bioturbation bottom image. Infauna deposits fines on surface ignoring bigger rubble chunks. Thus the patches of lighter color. [19:15:25] not a halosaur. [19:15:28] yeah, it is a very weird looking one [19:15:57] We used to call them spiny eels. but google come u with the wrong one. [19:17:11] Notocanthidae [19:17:40] snubnose spiny eel [19:17:57] I might note that on Great Meteor seamount the sediment yielded 56 species of harpacticoid copepods, of which 54 were new.... lots of stuff in the seds... [19:19:28] hannahmiller leaves the room [19:21:06] Territorial oreos? Wow. Didn't know that. That explains why one tried to take a bite out of the camera lens on a previous cruise.

[19:24:50] @Rhian: whatever they want. [19:25:00] :-) [19:25:24] Seriously though... I believe we have good video of one chowing down leg by leg in a brittle star [19:25:53] yes .. and feeding on small fishes too i think [19:25:54] and another one scooping fish eggs that had been laid on a rock. So, opportunistic. [19:26:27] the 2019 expedition with all the squids, the crabs were fighting over all the squid pieces [19:27:04] I have also seen them eating dead jellyfish [19:27:20] I have also seen them lunge for shrimps, but no successful catches yet in my records [19:27:25] Thanks everyone!
