The large eyes of Deania, plus reflecting tapaetum are adapations to gather as much light as possible. Another adaptation is an 'aphakic space' in the anterior end of the eye, so that the orbit is prolonged a bit anteriorly - allowing light to bypass the lens and go directly unfocused to the retina. In many fishes of this depth zone, just detecting light is more important than getting a focused image. See light, head that way, munch upon the light-producer [15:37:24] a common species in this area is B. fosteri (common name bloodbelly comb jelly) [15:41:49] LAT : 30.400884 , LON : -79.27586 , DEPTH : 831.8659 m, TEMP : 8.12643 C, SAL : 35.08729 PSU, DO : 4.99754 mg/l [15:44:46] There may have been a small Acanella colony by the bottle. [15:45:01] Not sure if you have been seeing those earlier - I just was able to tune in now. [15:45:12] Alternatively a small Chrysogorgia colony. [15:46:49] LAT : 30.400585 , LON : -79.275817 , DEPTH : 831.4675 m, TEMP : 8.1899 C, SAL : 35.0942 PSU, DO : 4.97206 mg/l [15:47:52] When we zoomed slightly to the bottle I saw lots of small colonies. So there are corals here, they are just small. [15:50:14] michaelvecchione leaves the room [15:51:02] We will be heading over a series of mounds today, with each mound increasing in height off of seafloor. At the slope toe for mound #2 [15:51:16] Much less coral rubble and much less populated than yesterday, Dont you think so? [15:51:50] LAT : 30.40032 , LON : -79.275923 , DEPTH : 832.5316 m, TEMP : 8.21715 C, SAL : 35.09797 PSU, DO : 4.95638 mg/l [15:52:29] dragonfish? Mid-water, bentho-pelagic coupling [15:52:36] Echiostoma if completely black [15:53:43] Steve Auscavitch leaves the room: Replaced by new connection [15:54:43] The shape of the photophore at the tip of the barbel is very important for taxonomy. [15:54:47] Stomiatoid midwater fish near the substrate: good example of a large adult midwater fish visiting the benthic boundary layer. That bioluminescent lure is just what would get the attention of midwater-fish munching Deania [15:55:32] That lure lured in too big a "prey", i.e. D2 [15:55:48] :-D lol [15:56:35] Hyalonema [15:56:50] LAT : 30.400247 , LON : -79.275837 , DEPTH : 830.3905 m, TEMP : 8.28583 C, SAL : 35.10588 PSU, DO : 4.95083 mg/l [15:58:34] You could see one of two large photophores under the fish's eye. One glows green, one red. These are stealth light organs, used to defeat the normal blue wavelength bioluminescence, and useful for intra-specific signalling. But some fishes like the Greeneye and the lizardfish Bathysaurus, and others, have yellow eye lenses to screen out the blue - allowing them to prey upon the midwater fishes that emit red light [15:59:46] No - Echiostoma only has blue photophores - the red are only found in Malacosteus, Photostomias and one other stomias who's name escapes me. No fish has been found that has green photophores (yet) [16:00:37] The actual common name for this is Venus' flower basket. [16:01:10] No, the yellow lens is used to screen out the broader spectrum background light, making the narrow spectrum blue bioluminescence relative brighter, basically breaking bioluminescent camouflage [16:01:51] LAT : 30.400161 , LON : -79.275846 , DEPTH : 830.3526 m, TEMP : 8.27981 C, SAL : 35.10521 PSU, DO : 4.9536 mg/l [16:01:55] The SeaTube annotations stop working again. [16:02:23] It has come off several times this morning just to let you know [16:02:33] It may be worth noting that although we use a single common name (or maybe we don't!) for these vase-like sponges, there are multiple species that have this basic morphology. [16:03:12] That is actually one of the "problems" with common names if you are trying to measure biodiversity and biogeographic ranges. [16:03:16] @Cris, could you please send a note to mashkoor.malik@noaa.gov, with a screenshot if you have any error messages [16:03:55] It was enlightening to see that large deep-water shark Deania cruising and gliding very slowly. Most sharks need to swim rather continuously and rapidly enough to keep from sinking. The very flattened head and body of Deania (and relatives) provides lift, which along with a fat-invested liver, enables Deania to stay aloft rather effortlessly [16:04:02] @Mike: at least on my chatroom window, your last post comes through as "object object", which in the past we've determined is a copy/paste issue from some specific platform. [16:05:06] Thanks Scott, I pasted mashkoor's email, mashkoor.malike@noaa.gov [16:05:22] @Scott, I had that problem yesterday. Try refreshing or logging back in. It seemed like a glitch that my internet didn't load. [16:05:25] @Mike: same result: "object object" [16:05:37] On mine, too. [16:05:47] Can we estimate the size of this corndog hexact? [16:05:55] Malacosteus has a large red light organ sitting just behind and below the eye. Then farther back along the upper jaw is a smaller but still prominent light organ that glows light green. [16:05:59] the email is: mashkoor. malike@noaa .gov (just eliminate the spaces) [16:06:10] I don't think it is an issue on my end - it is dependent on the users software and typically is when pasting. [16:06:36] @Kim: now you have an "object object". Did you do that intentionally as a test? [16:06:51] LAT : 30.400195 , LON : -79.275851 , DEPTH : 829.6746 m, TEMP : 8.31187 C, SAL : 35.10852 PSU, DO : 4.95405 mg/l [16:07:14] no, that was supposed to say "mashkoor . malike @ nooa . gov" [16:07:23] malik* [16:07:58] I think some hyperlinks show up odd based on either the sender or the program the receiver is using [16:08:10] @Kim: exactly. [16:08:21] sorry team I am not able to enter annotations, right now., it is not working [16:09:00] Sorry, but I've worked with Edie Widder and Peter Herring. They're measured the spectrum from just about every live fish that we catch in our nets - no green bioluminescence in Malacosteus. Does it perhaps irridesce or fluoresce green when room lights are on? [16:09:24] @Kim, @Mike: on an earlier cruise we narrowed down the issue. You can ask Kasey and she can remind us what "interface" it is that generates the problem. @Mike - what interface are you using? [16:09:32] I recommend trying to use on of the suggested programs. Pidgin or Adium [16:09:42] pidign [16:09:46] @Mike: I mean interface to comment in the chatroom. [16:10:10] @Mike: right. I think it may have been a pidgin issue. [16:10:24] Frank - I agree with you on screening out blue to break up biolumienscent camo, something used by predators looking up to feed on midwater fishes with ventral rows of photophores emitting blue wavelength. Many papers on this. But, consider Bathysaurus mollis living at 3000-5000 m depth where countershading against ambient light is not a factor. Bathysaurus preys upon both benthopelagic fishes, and notably on large midwater fishes with red light organs. Screen out blue - see red. [16:10:49] For some reason there is a problem with copy/paste in pidgin, or at least how it being received by some of the other interfaces. [16:11:24] @Mike: for troubleshooting, I'll note I am logged in to chatroom via Firefox browser. [16:11:41] good copy [16:11:52] LAT : 30.400042 , LON : -79.275855 , DEPTH : 829.0705 m, TEMP : 8.3436 C, SAL : 35.10977 PSU, DO : 4.95512 mg/l [16:12:31] CherylMorrison leaves the room [16:13:52] Ken - Only 3 fish have red bioluminescence, and that's all photophores. The yellow lenses block the longer wavelengths in the broader spectrum downwelling light, that the counterilluminators are trying to match. This makes their counterillumination relatively brighter than the background light, making them more visible to the animals with yellow lenses. No animals uses the extremely rare red luminescence to counterilluminate - just as sniperscopes to find prey. There is one chaetognath that may have red BL, but no one knows what it uses that for (yet)Tammy [16:16:21] shirleypomponi leaves the room [16:16:52] LAT : 30.400117 , LON : -79.275801 , DEPTH : 827.2474 m, TEMP : 8.37223 C, SAL : 35.11442 PSU, DO : 4.93042 mg/l [16:17:11] very different appeareance of the bottom [16:19:14] Yes [16:19:25] this is a different one [16:19:48] This strikes me as a "young" colony. [16:20:06] Not a different species; just a different morphology. [16:20:17] The main body is still developing... [16:20:22] The "tip" is just everted. But it's not the corn dog sponge. [16:20:37] There is lots to be done in studying development and life history in these deepwater sponges! [16:21:04] Those are my "spiculations" [thanks to Sarah Bingo for that pun] [16:21:12] Frank - we should discuss green light organs by email jumpingsturgeon@yahoo.com. I worked for 1.5 yrs in the IOS lab with Herring and the rest of the fish group, sailed on the Challenger for deep-sea fish missions. Great crew back then. Regarding Malacosteus, I have seen freshly trawled specimens with red and light green cheek organs still glowing under ambient light when landed. We did place midwater fishes and other organisms under short and long UV in a dark lab of several of my own cruises. In Malacosteus, the whole side of the cheek and other parts of the head fluoresced either purple or red. The red light organ still appeared its normal red, the 'green' light organ did not fluoresce if I remember correctly. Long time ago. I have photos somewhere. [16:21:53] LAT : 30.400062 , LON : -79.275736 , DEPTH : 826.844 m, TEMP : 8.35963 C, SAL : 35.11328 PSU, DO : 4.92993 mg/l [16:21:59] Yes different morph and probably different developmental stage like Scott is suggesting [16:22:07] signing off - nice fish imagery today [16:22:11] kennethsulak leaves the room [16:22:15] thanks ken [16:24:09] Fluorescence it not bioluminescence - requires a light source. Can't see most BL under ambient light. Lots of early papers mistakened irridescence and fluorescence for bioluminescence - not the same thing. Echiostoma light organ looks purple under room light, but still bioluminescence [16:24:55] Maybe they're just hanging out together, chillin' and watched passing ROVs... [16:25:36] Is anybody having trouble with the SeaTube annotations? Neither Cris nor I can enter data. We're each logged in, and we can actually type in the data, but we don't see the entries recorded. Just wondering if anyone else if having the same issue. [16:25:54] Sorry- meant to say Echiostoma looks purple, barbel looks blue and pink, but all bioluminesce blue. I'm happy to continue this at your e-mail, but there is so much misinformation about "different colors" of bioluminescence because so many documentaries call irridescence bioluminescence - like what we saw with the ctenophore - that I want to co0rrect this now.

[16:30:29] OK. Thanks, Scott. [16:30:36] I would suggest to keep inputting if possible, maybe it's archiving the inputs but not displaying. [16:30:59] Will do.

Look at the time stamp of your entry and then scroll up the page to that time and you should find your annotation. [16:32:28] I'd guess ascidian [16:32:38] Yeah, I see that. In fact, one of the notes I made was added on to an existing note. [16:33:08] It appears what is happening on my computer is that the time stamp is not updating - it is stuck on 1104... [16:33:29] Looks like an ascidian to me, too. [16:34:02] it looks more gelatinous than spongy...so colonial ascidian? [16:34:15] Yes, Megan. I agree.

At first I thought they werer hydroids, but now I think they are bryozoans. Thoughts? [20:19:56] I sent out the bat signal.

[20:21:27] @Scott I think so? I haven't noticed any bryozoans this dive so maybe I've been thinking they're hydroids. But I've mostly been at the microscope and listening.. [20:22:11] They have been quite abundant. Hopefully we'll come across another. You have to be at just the right angle but it sure looks like little cases along the side branches.

[20:23:49] Here is one! [20:23:57] To left of sponge [20:24:19] I think maybe a hydroid [20:25:05] uhhhhh [20:26:15] I see what you mean Scott! As far as I know there aren't any bryozoans that grow like that so I'm going to stick with hydroid [20:26:21] Stumped like me, eh... [20:26:32] chat-admin leaves the room [20:26:39] I thought bryozoan with a ? [20:26:51] christarabenold leaves the room [20:26:54] Yeah, everything about the gross morphology screams hydroid, but the close-ups make me question that.

[20:30:02] meganmcculler leaves the room [20:31:06] Chris Mah confirms Solaster for the 8 armed star [20:31:31] Nice!

[20:35:20] Solaster yes, did Chris suggest a potential species name? [20:36:08] Chris did not suggest a potential species name. His exact response: "Solaster! likely diggin' around for brittle stars to eat in that hole!" [20:36:34] what is that unbranched whip in front of isidid? (unfocused [20:37:18] LAT : 30.397668 , LON : -79.276471 , DEPTH : 827.8599 m, TEMP : 8.32082 C, SAL : 35.10986 PSU, DO : 4.99108 mg/l [20:37:23] @Tara- hahaha [20:37:46] Trees and corals- convergent evolution :-) [20:38:38] @TIm, exactly [20:38:55] @Asako: I think that is a Caldarisis [20:39:03] argh! Cladarisis [20:40:00] @Scott the unbranched one? I missed to hear your comment on phone [20:42:18] LAT : 30.397658 , LON : -79.276482 , DEPTH : 827.6493 m, TEMP : 8.32997 C, SAL : 35.11062 PSU, DO : 4.98116 mg/l [20:45:32] @Asako: yes, the one that appeared unbranched (It probably had branches lower down) [20:46:31] @Scott thank you. [20:47:19] LAT : 30.39757 , LON : -79.276483 , DEPTH : 827.7483 m, TEMP : 8.34 C, SAL : 35.11222 PSU, DO : 4.95564 mg/l [20:48:02] @Asako: more specifically, it is part of the S1 clade. The only taxon in the S1 clade that has been described so far is Cladarisis nouvaniae, and so I refer to S1 clade isidids as Cladarisis. [20:48:42] @Asako: but it is interesting that S1 clade is very common and widespread - both Atlantic and Pacific [20:51:27] @Scott that's interesting.
