[14:46:19] Octocoral [14:46:24] Probably genus Radicipes [14:46:42] which is a Chrysogorgiidae [14:46:56] This genus can live anchored in soft sediments [14:47:04] Chrysogorgid [14:47:11] (Tina)Radicipes [14:47:16] Venom from the deadly cone snails have been developed into Prialt a treatment for chronic pain [14:47:19] But this is a pretty shallow depth for it, I think.

I have a tentative ID for it: Duckbill flathead, Chrionema chryseres [14:50:42] christophermah leaves the room [14:51:02] There are a few zoanthids that can generate their own skeleton, so perhaps that is one example...? Not sure what else would build a skeleton like that. [14:51:29] But otherwise I agree with Joana that typically zoanthids overgrow an existing structure [14:52:34] @Scott we thought the skeleton may be black coral. [14:52:50] at the previous dives [14:52:54] Yeah same fish, but I think its just blinded by the ROV lights. They appear to be very visual species. [14:53:29] Think its distubed by lights [14:53:33] (Tina) greeneyes? [14:53:35] disturbed [14:53:53] @Asako: perhaps. But then that is very thick zoanthid tissue on the black coral. [14:53:58] (Tina) may be dial migration? [14:54:01] This is not a greeneyes [14:54:05] but certainly a possibility. [14:54:34] @Scott anyway, we always find these type of zoanthid where we cannot collect samples!!

[14:55:59] A lot of the small fishes with the bluish and greenish scales all appear to be deep sea cardinal fishes in the genus Epigonus.

[14:56:33] the preference may vary by species [14:56:44] I thought it was a coral [14:56:49] on the left [14:56:55] @Scott (Tina) ask scott about reference on their own skeleton? [14:57:08] (Tina) right of crinoid is probably scallop [14:57:14] (Tina) very tiny one [14:57:25] (Tina) it was possible to see mantel [14:57:27] Get ready to see all the squid as I have to log off for a couple hours :) [14:57:33] @chris what's the name of the trail-making urchin? [14:57:49] The branches ("arms") on the white thing behind that crinoid did not all come out of the same place, so don't beleive it was a crinoid [14:57:51] (Tina) at Hawaii they are sitting at Paragorgia [14:58:06] I thought their own skeleton zoanthid is Gerardia...

[15:02:24] @Tinasako: For sure I agree most zoanthids are epifauna, sitting on or overgrowing other fauna (corals, sponges, especially). But we know of at least some examples of species that can then build their own skeleton from that starting point, e.g. Gerardia and the one "gold coral" from the North Pacific (can't recall genus name right now) [15:03:06] This is greeneyes! [15:03:35] shortnose greeneye fish Chlorophthalmus [15:03:40] @Scott Gerardia is what I thought. [15:03:52] Brisingidae!

[15:23:35] @Asako: the only reason I didn't suggest polychaete is that there seemed to be many openings. [15:24:22] @Scott I have collected the similar one before. I have been thought it was polycheate!! maybe I was wrong... [15:24:25] @Asako: but it did have the right diameter and texture for a polychaete tube [15:24:41] @Scott is it the pdf entitled "A Photo Guide to Deep-Sea Fishes of Coral, Canyon and Cold Seep Habitats along the U.S. Atlantic Margin" I do have this one [15:24:43] LAT : 17.583298 , LON : -64.870595 , DEPTH : 517.3106 m, TEMP : 11.85748 C, SAL : 35.50673 PSU, DO : 4.28358 mg/l, TURBIDITY : 1.2821 FTU [15:24:55] @Scott but it was definitely tube.
