Humans love the big, the dramatic, and the colorful. Thus, corals get lots of attention. Not so much for the drab, brown-gray sediment surface-dwelling small organisms - which are highly diverse, wonderfully adapted, and with unusual life styles. OE needs to add a new tool, a benthic crawler with close-up imagery capability - time to take stock of the mud-dwellers [16:20:41] old adult red crabs get deep dull red, sometimes almost black [16:21:42] Another Witch Flounder, abundant enough to be an item in the commercial trawl fishery - marketes as 'gray sole' [16:23:10] LAT : 40.851193 , LON : -66.540839 , DEPTH : 1016.6797 m, TEMP : 4.4543 C, SAL : 34.96233 PSU, DO : 8.07851 mg/l [16:23:43] Note the very small mouth of the Witch Flounder, a muncher of very small benthic inverts, such as worms.

Great job! Thank you! [17:44:23] Javier, do you know anything about the commesal shrimps int he sponge? [17:47:12] I'm pretty sure we've seen this yellow sponge on the New England Seamounts, though I don't recall it being collected. [17:48:02] Hi Meagan! I identified the specimens in the Dictyalus in the past but I do not remember the name now (I will check). However, as you mentioned, this could be another specimen and perhaps another shrimp species associated? It will be super interesting to know [17:48:18] LAT : 40.853222 , LON : -66.539658 , DEPTH : 933.0941 m, TEMP : 4.53969 C, SAL : 34.96794 PSU, DO : 8.01403 mg/l [17:48:55] Megan can't see all the corals here for the sponges! ;-) [17:51:04] Example of previous image: https://oceanexplorer.noaa.gov/explorations/04mountains/logs/may23/media/coral_sponges.html [17:51:13] I am not sure if this could also be Hertwigia but it would be great to confirm it [17:52:31] i think i remember hearing herwigia comes in yellow?

It usually comes in yellow [17:54:32] By "previous image" earlier I meant one example of the observation of this yellow sponge in the western North Atlantic. [17:55:33] well now we have a white "hertwigia" and yellow one to compare [17:55:36] There is only one species in the genus (Hertwigia falcifera). It will be interesting to check! [17:55:51] yes! it will be really good to compare both! :) [17:56:01] I've always wondered what that bright yellow sponge was so it will be great to find out! [17:56:25] Acesta bivalves, as well. [17:56:51] Most organisms with well-developed coloration have an adaptive reason to be so colored. Wonder what is happening with this dramatically yellow sponge, and also the encrusting purplish-blue sponge from similar depths??? Would be cool to apply the Eddie Widder UV light to see if this sponge fluoresces.

Unexpectable [18:12:09] but septae are invaginating betweem mesenteries.... so the tentacles.. so it is logic [18:13:18] @Meagan and @Francisco The yellow coloration of that Hertwigia likely comes from a small molecule called uranidine that is commonly seen in quite a few sponges (deep-sea/shallow and hexactinellid/demosponge). When exposed to air or EtOH it rapidly oxidizes and turns into a black precipitate. The ecological purpose for this compound is still unknown.

I'm spending my days in the Atlantic and my nights in the Pacific these days, everything looks the same some days [18:37:51] I was told they are Limidae and the taxa name is Acesta [18:37:55] Looks like a small Lophelia below the Acesta [18:38:08] @Meagan If this sponge changes colors, could you please send me pictures?

[18:59:33] it seems another species than the 'G. barretti' we collected [18:59:35] Is it possible the yellow sponge on the side is actually a different sp. or is it all one? Its this bicolor pattern usually observed? [18:59:49] the yellow one may be another one, give me a second and I will give you the name [19:00:09] collect the chiton with the sponge? [19:00:13] Is it possible that the sponge is upside down? i.e has it been dislodged, or knocked off of a rock? [19:00:15] I can also give you some names for the chitons, in fact, there is one (Hanleya nagelfar) that I think feeds on sponges [19:02:11] and the yellow one perhaps is another sponge - Hexadella dedritifera, that is common on Geodiids and other astrophorids (SubOrden Astrophorina) [19:03:25] LAT : 40.85347 , LON : -66.539588 , DEPTH : 919.4902 m, TEMP : 4.58634 C, SAL : 34.97043 PSU, DO : 7.92856 mg/l [19:03:26] That would explain the bicolor appearance! And different textures. [19:05:15] Javier, what should I called the sponge? Geodiidae? [19:06:50] This view convinces me there are 2 sponges, one layered on the other. [19:07:06] Hanleya hanleyi is the actual name I was referring (Hanleya nagelfar has been synonymized (sorry for that). However, a positive ID would require the sample and I think that there were 2different species of chitons as well [19:07:17] Would the yellow one eventually completely overgrow the lithodid? [19:07:38] one looked to me as Placiphorella but it is hard to type and watch at the same time, lol! [19:07:54] Where are the incurrent ostia of the geodid? Are they blocked by the yellow sponge? How does the geodid then survive? [19:08:26] LAT : 40.853458 , LON : -66.539597 , DEPTH : 919.5102 m, TEMP : 4.57773 C, SAL : 34.9694 PSU, DO : 7.95838 mg/l [19:09:54] I would call the white Geodia, but I think the yellow is different (Hexadella dedritifera) [19:12:37] Hanleya nagelfar, a sponge-feeding ecotype of H. hanleyi or a distinct species of chitonhttps://www.tandfonline.com/doi/abs/10.1080/00785326.1991.10429706 [19:13:11] nowadays both species of chitons are synoymized [19:13:26] LAT : 40.853448 , LON : -66.539725 , DEPTH : 920.521 m, TEMP : 4.59048 C, SAL : 34.96927 PSU, DO : 7.93693 mg/l [19:13:34] Javier, should I take a genetic sample of both the inner portion of the sponge and of the yellow outer part? [19:13:51] Great you collected the samples! This will help to know for sure! [19:14:16] Yes! For the genetic sample I woulld take one for the inner portion and another for the yellow outer part [19:14:18] @Megan: Absolutely you need to preserve separate samples for genetics. [19:15:32] Don't know about this species in particular, but Paragorgia comes in at least 3 colors: red, pink and white, so that isn't iunusual. [19:17:36] Thats what I thought but Tim told me that this color wasnt as well known from this area [19:17:47] We've collected white P. johnsoni from the New England Seamounts that look like this; not genetically different from the red or pink ones, at least in the standard markers. [19:18:06] thats interesting [19:18:21] There was so much going on this sponge. From experience in northern waters around the Grand Banks of Newfoundland and Flemish Cap area we have seen similar things. Two chitons that could be 2 species (Hanleya hanleyi and Placiphorella sp.). For the sponges I would say the white is a Geodia (could be Geodia phlegraei) and the yellow Hexadella dedritifera, but great you got the sample!!

Both sponges belong to the suborder Astrophorina although they are in different families. You may see more of this ‘Geodia’ type sponge with the yellow covering, so I would keep in mind for future that could be Geodia or Stryphnus. It is very difficult to say from the video and great that you collected the sample. Our colleague Paco Cardenas is a specialist on these sponges and he may be able to say from the video. However, with the sample will be straightforward to know [19:35:06] It looks like it is pulling the guts out from inside the mantle rather than eating the mantle muscle.

Seems unlikely he could catch it, unless it fell from another predator (squid or fish)? [19:39:32] Crab got it from someone else, I wager. [19:39:54] my thought @bradley is that the squids attacked eachother [19:42:41] @scott, do you have a guess of this bamboo coral?

[19:44:13] Still haven't seen any nodes on this colony. We moved too soon to the crabs! [19:44:19] barryeakins leaves the room [19:45:42] Regarding black viscous fluid exuded from soft corals, Callogorgia americana colonies that have snakestar commensals exude a black fluid just where the snakestars are attached - when physically removed. Black fluid may be a sulphide - I have wondered previously if there is a chemical exchange going on between host and commensal [19:45:55] Bradley, Scott, and Megan -- I would not be surprised if the squid was decapitated by another squid. [19:46:29] thanks for the info @scott! It will be great to see what turns out when you compare with your databasee. We thought that it was different to other bamboo corals collected previously in the area. In the Gully sample it was also hard to see the nodes, but we saw them at the end! Thank you!
