[19:49:46] (Tina) better to look at polyps to know if the coiled black coral is Sticopathes or not [19:49:56] (Tina) normally if they are yellowish - more chance Aphanostichopathes [19:51:04] if we could see another coiled black coral, could you please have a quick zoom to see the polyps?

[19:57:06] @Megan, yes, we saw a few, no idea about the species [19:57:38] Little baby Halosauridae [19:57:41] sorry, the pilots had to move so we couldn't zoom in on the coral [19:57:55] could we have a zoom next coiled black coral? [19:58:08] Thank you! [19:58:23] @Nolan oh wow that's an amazing photo! Sad I missed it but thought I would take the opportunity to do a couple things while the dive was paused [19:59:29] Glad you got it! Yup, totally understood! I'm reading a manual to fix a DI water machine. [19:59:34] We would need a sample to ID, but i know at least A paucispina has coil near the tiip. Maybe also true for A. spiessi? [19:59:35] (TIna) I think Aphanostichopathes. do not thing paucispina [19:59:40] thank you for the zoom!! [19:59:43] @jeremy, was that useful? [20:00:00] it's a cheilostome bryozoan. I could try to go further than that [20:00:43] Thanks! Maybe we can get a rock with a bryo and sponge on it!

[20:02:19] Yes @Tina [20:03:31] thanks [20:04:40] @Joana Given that the closest Hyalonema had its stalk also uncovered, I think the current was strong enough at one point to blow away the top layers leaving both sponge more exposed.

[20:14:02] christophermah leaves the room [20:15:02] slime star! [20:15:10] Just joining the dive now. Looked back for fishes. First encountered was a halosaur, genus Halosaurus. There was some front line discussion of why zooming in on head. The zoom on this specimen revealed scales on the top of the snout = diagnostic feature that identifies this genus versus genus Aldrovandia. Zoom shows small unpigmented nostrils = a female; males have larger black nostrils, that get greatly enlarged during spawning season. Zoom in also reveals a 'see-through' skull, frontal bones are transparent and unpigmented. That allows light to strike the pineal organ, used to coordinate seasonal spawning and gonad maturation. Sunlight is extinguished at 1100m [20:15:17] oh wow! a pterasterid! [20:15:27] nice [20:15:33] yes.. like Hymenaster o perhaps pteraster [20:15:51] @Ken Thank you for the clarifiation! [20:16:21] calkingh [20:16:23] LAT : 19.04358 , LON : -67.568981 , DEPTH : 1450.2063 m, TEMP : 4.28402 C, SAL : 34.99138 PSU, DO : 6.30777 mg/l, TURBIDITY : 0.989 FTU [20:16:44] But, the bathymetric range of halosaurus gets fish into the dim sunlight range above 1000 m. Breeding males have that pineal window occluded with intense black pigment. So, by zooming in - you gain a lot of ID and sex and life cycle information [20:18:39] @Ken if in Halosaur male is bigger than female or vice versa? [20:19:41] Another bamboo! [20:19:48] (Tina) black halosaur was pretty small [20:21:21] LAT : 19.043691 , LON : -67.56893 , DEPTH : 1443.5123 m, TEMP : 4.28898 C, SAL : 34.98591 PSU, DO : 6.13003 mg/l, TURBIDITY : 0.9768 FTU [20:22:00] christophermah leaves the room [20:25:54] going to step away for about 20 minutes, so I'm sure you'll come across some great bryozoans [20:26:22] LAT : 19.043753 , LON : -67.568925 , DEPTH : 1438.1967 m, TEMP : 4.29472 C, SAL : 34.99066 PSU, DO : 6.2401 mg/l, TURBIDITY : 1.6545 FTU [20:26:31] (Tina) Chrysogorgia [20:26:45] So, a second halosaur observed had the large jet black nostrils, and no scale on top of the snout = male Aldrovandia. Dirty white body color = A. affinis. Also has the see-through top of the skull condition - so a male, but not yet in spawning condition. [20:27:07] (Tina) interesting it is almost stright near the base [20:27:24] @Ken thanks [20:27:50] Metallogorgia [20:27:57] the first one [20:28:12] @Asako @Tina So maybe the little Chryso that just saw could be baby Metallo? [20:29:31] maybe, I bit thought it might be baby Metallo [20:29:37] (Tina) @nolan, I am thinking that you may be right, but there so many Chryso in Carribean [20:30:02] Great, thank you! [20:30:36] (Asako) for me, its more like Chryso...

[20:45:09] Oh this one has a really ruffly almost bubbly oscular surface [20:46:24] LAT : 19.043979 , LON : -67.569081 , DEPTH : 1428.0861 m, TEMP : 4.30377 C, SAL : 34.99143 PSU, DO : 5.73817 mg/l, TURBIDITY : 0.9646 FTU [20:46:47] (Tina) one without stalk had several osculums [20:46:49] Isn't this a shorter version of what was collected earlier? [20:47:35] @Scott I thought it was different... same? [20:48:20] @Scott I don't think so, unless its a case of the darker orange one that we collected is compressed like the "sneezing" behavior noted ealrier this year. [20:48:44] To be fair, [20:48:58] (Tina) i read somewhere that sponge can contract, so if you look at contracted and uncontracted specimens at photo you cannot take them for one species [20:49:00] I haven't been paying enough attention to have a legitimate opinion. [20:49:19] @Joana Do you know about the behavior I'm describing? The main sponge body was seen in a timelapse to compress and then expand again. [20:49:40] @Asako Exactly what I was thinking of. [20:49:55] @scott and all, I think we have 2-3 different Hyalonema species here. I didn't want teh dive to be a full sponge collection one. Any corals of interest? If not, I think we will collect 1-2 sponges more [20:49:59] But my impression was that it was "simply" one whose stalk had not grown as tall. But again - I have been in a lab meeting and not totally focused on the video, so I defer to you experts. [20:50:04] @Nolan its Tina! [20:50:26] @Asako and @Tina Gotcha thanks! [20:50:29] From what I have seen the spoges are dominant, so lots of collections seems approporiate. [20:51:08] @Scott Did you also want to see another bamboo upclose before deciding to collect? [20:51:25] LAT : 19.044271 , LON : -67.568903 , DEPTH : 1420.4891 m, TEMP : 4.3057 C, SAL : 34.99668 PSU, DO : 6.6688 mg/l, TURBIDITY : 0.9951 FTU [20:51:41] Tina also think that black coral we are seeing has been already collected a lot from this area. [20:51:53] @Deb This rock reminds me of a well laminated pastry...No I am hungry... [20:51:59] (Tina) what is groing at top of big one? [20:52:14] too late( [20:52:19] @Nolan: yes, I haven't had enough look to be able to recommend any collection. [20:52:21] @Tina I believe Jeremy was interested in collecting one too [20:52:37] (Tina) Madrepora? [20:53:07] @Nolan (Tina) Jeremy was looking at branched one [20:53:13] primnoid? [20:53:28] Primnoidae [20:53:41] the first primnoid [20:53:43] Looks like genus Narella, as a first guess. [20:54:07] 2-3 per verticil [20:54:16] @Tina Oh, I thought he was referring to the Aphanostichopathes because he said he wanted to compare it to the one he had just described.
