[17:10:35] Oh! Never mind! We have moved already! [17:10:50] Don't go back. [17:11:08] They had to move away to get the tray out/bioboxes [17:12:07] No worries, I understand.

Not having seen the first part of the dive I can't comment on whether there might have been anything worth going back to sample. [18:02:03] yes, you can tell that species from others by the characteristic dark blotch on the dorsal, spots on the cheeks, and a lateral line witth white spots at intervals [18:02:06] irissampaio leaves the room [18:02:26] robertcarney leaves the room [18:02:26] @cheryl thanks for the shout out too :) [18:02:41] We saw a striped-tentacle cerianthid like this in the GoMex [18:02:47] I do not know the sp [18:03:01] @andrea- thank you!

[18:04:00] @scott was the collection just ~~10 min ago an anemone or corallimorph? [18:04:19] @Andrea: great question. That was one of the reasons we collected it! [18:04:29] Corallimorph most likely [18:04:45] LAT : 34.503191 , LON : -75.697886 , DEPTH : 334.6031 m, TEMP : 7.88528 C, SAL : 35.04997 PSU, DO : 4.41435 mg/l [18:04:51] @Andrea: but my initial thought was corallimorph based on the width of the oral disc relative to height of column. [18:05:00] Or at least my hope! My first look at a live one if so [18:05:00] irissampaio leaves the room [18:05:02] @scott. thanks! my video was on mute…trying to get the baby to sleep but i was watching [18:06:58] so many BBRF here!

It's Kim from NOAA and we are watching you from Stennis! [18:38:30] I made that joke on twitter before - instead of bryozoologist I could be considered an ectoproctologist [18:38:43] @Megan: Oops! My bad. I meant "ectoproctologist". Don't tell my Invert Zool students! I believe it was Ken Halanych who said he preferred the phylum name Bryozoa over Ectoprocta because he wanted to be known as a Bryozoologist rather than an ectoproctologist. [18:39:01] @ Hi Kim! Kim Valentine? [18:39:15] @Megan: but maybe Ken stole it from you! [18:39:30] Yes, it's me Kim Valentine! [18:39:45] @Scott Oh that is hilarious!
