[12:58:34] Alepocephalids are called slickheads or smoothheads - due to the lack of scales on the head. They are not particularly slimy (except one genus).

However, I wonder if some do not also feed facultatively in midwater, especially the very active swimmers?? Indeed, the highly-modified genus Pelagothuria never descends to the substrate - so much feed pelagically [13:20:38] Can [13:20:44] 't quite tell.

Sorry for late ID - got bumped off the feed [13:48:12] Thanks, Ken! I'll go switch the annotation [13:48:42] allencollins leaves the room [13:49:01] LAT : 38.016556 , LON : -26.781018 , DEPTH : 1555.8424 m, TEMP : 4.90244 C, SAL : 35.0858 PSU, DO : 7.73747 mg/l, TURBIDITY : 0.9402 FTU [13:51:22] Thanks Ken. I have been having trouble with the feed today too, but I am out at my cabin in the woods so I assume mine is a local problem. [13:51:53] Squalogadus lacks a first dorsal fin - only such macrourid I think. Big inflated head is a floatation device. Sometimes this fish is seen close to the seafloor, but may be more typically deep pelagic. [13:52:46] Mike - same here - rural location with funky DSL that fails frequently [13:53:56] jaymesawbrey leaves the room [13:54:01] LAT : 38.016989 , LON : -26.780816 , DEPTH : 1405.2532 m, TEMP : 5.63385 C, SAL : 35.17215 PSU, DO : 7.42109 mg/l, TURBIDITY : 0.928 FTU [13:54:57] daphnecuvelier leaves the room [13:55:30] taraluke leaves the room [13:55:44] Note on distinquishing Etmopterus lantern sharks from closely-related velvet dogsharks. Etmopterus has a lower, longer caudal fin almost in line with main body axis. Centroscymnus and Scymnodon and related genera placed in family Somniosidae now are fatter midsection and have a kind of shortish diamond shaped caudal fin [13:57:12] My preferred solution is to ask a fish person. [13:57:16] Thanks! I was just trying to pull up a key to the genera to figure that out haha [13:57:23] Otherwise general body shape and fin position is similar in both groups of deep-living black dogsharks [13:58:50] allencollins leaves the room [13:59:02] LAT : 38.017237 , LON : -26.780742 , DEPTH : 1255.2451 m, TEMP : 6.84003 C, SAL : 35.36311 PSU, DO : 6.87108 mg/l, TURBIDITY : 0.9402 FTU [13:59:45] words of wisdom for differentiating the Squalogadus from other fish that look similar (like ophidids and liparids)?

Only somewhat similar fish is the blind cusk eel Typhlonus nasus - large nostrils, no eyes [14:03:41] cyclothone? [14:03:49] yup that was a cyclothone [14:03:57] okay, thanks Ken!

I think it emulates swimming holos - drifting/sculling off-bottom, using off-bottom currents to move to a new benthic feeding location, descending periodically [14:04:43] Ashley, sisnce you and Ken are on I am going to stop pretending to know the fishes. [14:05:08] you're faster with a lot of these IDs then I am, Mike haha [14:05:28] taraluke leaves the room [14:05:34] I'm so busy annotating that I don't get a chance to stare at the fish so you're tentative IDs are actually very helpful!

I might be able to ask them to flush it... [14:10:32] sorry - 1900m [14:10:55] allencollins leaves the room [14:11:13] we still have 3 empty canisters, correct? [14:11:22] yes, three empty canisters [14:11:29] @mike - do you know anyone that would want the benthic holothurian? [14:11:31] Deborah, can you wait to flush until all of the other canisters are full? [14:11:32] kennethsulak leaves the room [14:11:56] I suspect it is not very valuble. [14:12:05] yes, i can certainly wait. i can check to make sure it's possible or not too.

Another interesting point, the next time we see one is that red is a good color because most organisms that can see in the deep sea don't see the color red, so it makes them extra-invisible.

If not no worries any picture's will be amazing help [14:40:20] The black ctenophore will hold up for a bit under the photography set up if kept cold. Maybe 10 minutes or so. If you can get images with very strong sidelighting, it will be very helpful. [14:41:16] @allen, we will do our best [14:41:19] This is great. A lot of hidden diversity in this genus Bathocyroe, but this is reasonably close to type locality for B. fosteri. [14:41:37] is there a maximum time we can keep it before it degrades? [14:41:42] @Joana, I know you will! And whatever is possible is enough. ;-) [14:42:19] ya they must be kept cold or their body starts to disintigrate like the witch in the wizard of oz [14:42:25] Shrimp, same species as before [14:42:45] taraluke leaves the room [14:43:11] @mike, can you write the shrimp species here, if you know? I'm just back from lunch so may have missed it [14:43:19] @joana, there is variability. One cydippid I was looking at on board started disintegrating within 5-10 minutes of photographing. It started to change shape, then the combs started to break off. If you see that starting, pop into perservative [14:43:42] Not sure on species, will send off to Tammy Frank and Heather Bracken-Grissom for IDs after the dive though [14:44:07] LAT : 38.019246 , LON : -26.778703 , DEPTH : 1200.1675 m, TEMP : 6.99004 C, SAL : 35.36672 PSU, DO : 6.78148 mg/l, TURBIDITY : 0.9341 FTU [14:44:51] discarded larvacean house [14:45:49] an Allen animal [14:46:26] That was halicreas minima [14:46:34] michaelvecchione leaves the room [14:46:49] @allen, ok, we will do that.

If there is loose tentacle on the cydippid, that can serve as the subsample for genetics. Or if you can pick some of the tentacle off, that would work. The remainder of animal can go into formalin, and with fingers crossed we will get something to actually examine for morphology. And a huge thank you.

Didn't get good look at possible Rhopalonema. [17:32:08] Deiopea like?? [17:32:26] @Allen, I have a timestamp I'll send you [17:32:30] neuscampanyallovet leaves the room [17:32:38] maybe a younger bathycyroe [17:32:43] Its a lobate for sure [17:33:13] Colobonema? [17:33:15] Rhopalonema I think on that one [17:33:41] strange ctenophore [17:33:51] Thalassocalyce [17:34:00] This is the medusa-shaped lobate [17:34:06] thats it...I couldnt remember how to spell it [17:34:11] Exactly.

[17:38:30] Colobonema [17:38:49] We could sample for sure. [17:38:53] beautiful [17:39:17] Has been sampled from Pacific a lot. And so cryptic species always a possibility.

Looked like a possibility. And if so, pop em in EtOH. :) [17:46:56] EX2206_DIVE03 ROV Ascending [17:47:12] And there goes Solmissus! [17:47:27] it was teasing you. [17:49:19] @allen, if we see any tentacles we will just get them individually preserved in EtOH [17:49:29] LAT : 38.019388 , LON : -26.77802 , DEPTH : 518.3702 m, TEMP : 11.7962 C, SAL : 35.56613 PSU, DO : 6.21463 mg/l, TURBIDITY : 0.9463 FTU [17:49:50] as we wouldn't be able to tell from whom they come from :-D [17:51:47] Hi all- great dives. In my dives with the Johnson-Sea-Link submersibles we would often turn off all lights to see how deep we could still make out the basket on the sub from just surface light. I think about 600 m in Bahamas. Mike and Allen- how deep do we know that mammals, fish and inverts sense surface light?

They can swim faster with stem pulled in. Some pull the stems in very quickly [18:00:00] Hi John -- According to a slide I stole (I think from Peter Herring's book) the limit for crustacean phototaxis in clearest seawater is about 650 m. For detection of light by deep-sea fishes it was shown as 1000 m. [18:01:05] chaetognath [18:01:24] @mike Thanks I wonder about whales with those huge eyes. [18:01:36] @MV, very interesting. Thanks for answering that. When the bathypelagic starts. . . [18:01:44] Copepod [18:02:51] deep-diving whales are using sound. Architeuthis use their big eyes supposedly to detect stimuated biolum around the whales. [18:03:32] Bioluminescence decreases in fishes below 1000m - which suggests less reliance on vision below those depths as well [18:04:14] GeorgeMatsumoto leaves the room [18:04:31] LAT : 38.019807 , LON : -26.778801 , DEPTH : 500.5981 m, TEMP : 11.87213 C, SAL : 35.56735 PSU, DO : 6.23994 mg/l, TURBIDITY : 0.9585 FTU [18:05:07] hatchetfish [18:05:32] doing what HArbison said they do.
