[21:44:50] arvindshantharam leaves the room [21:45:12] I will need to check..but I THINK Aporocidaris [21:45:26] Don't usually see pencil urchins on sediment right? I thought the spines were used to wedge into rocks. [21:45:31] last time collected in 1906 [21:45:42] LAT : 55.928504 , LON : -152.919207 , DEPTH : 2989.5549 m, TEMP : 1.56378 C, SAL : 34.64997 PSU, DO : 3.39856 mg/l, TURBIDITY : 0.9463 FTU [21:45:47] These are older.. spines lack skin.. [21:46:00] so stuff grows on them... Cidaroid urchins date back to the Paleozoic [21:46:55] samcandio leaves the room [21:48:38] Sorry got the nudi structure backwards the pinks dots were the rhinophores. The other end were the gills reference to the function of the rhinophores as an organ of "smell". We smell scents and odors with our nose, which has special receptors to sense the chemical molecules in the air. In nudibranchs, and other marine animals, the same sort of chemicals are dissolved in the sea water. In many Sea Slugs this is how they find their food. Scent receptors work better when there is a lot of surface area to test for the chemicals [21:50:43] LAT : 55.928415 , LON : -152.91947 , DEPTH : 2983.4107 m, TEMP : 1.56517 C, SAL : 34.65067 PSU, DO : 3.35294 mg/l, TURBIDITY : 1.0073 FTU [21:50:46] Another Hymenaster [21:50:48] lasers? [21:50:51] SLIME STAR! [21:51:07] how big is it? [21:51:57] ah sorry chris I got distracted. oops! [21:52:44] More of those beautiful sprial radicipes bamboo corals [21:54:45] samcandio leaves the room [21:55:08] Tina: another Liponema [21:55:44] LAT : 55.928434 , LON : -152.919508 , DEPTH : 2980.8882 m, TEMP : 1.56252 C, SAL : 34.64962 PSU, DO : 3.45047 mg/l, TURBIDITY : 1.5018 FTU [21:57:55] kellymarkello leaves the room [22:00:38] what's that long trail? [22:00:44] LAT : 55.928396 , LON : -152.919596 , DEPTH : 2977.7028 m, TEMP : 1.56138 C, SAL : 34.6495 PSU, DO : 3.40921 mg/l, TURBIDITY : 1.2332 FTU [22:00:54] looks like a half-buried urchin plowing through the sediment? [22:00:57] samcandio leaves the room [22:01:07] oh, acorn worm [22:01:12] neat [22:01:30] rhianwaller leaves the room [22:01:49] TIna: agree for anchor worm [22:02:00] kellymarkello leaves the room [22:02:01] jamesconrad leaves the room [22:02:57] seanrooney leaves the room [22:04:21] wood falls do support some pretty unique communities [22:04:35] Zoom on the wood would be great...small white star critters??? [22:04:43] Tina: Munidopsis [22:04:46] bacteria and fungi, plus xylophagaid bivalves [22:04:51] starfish also [22:04:57] looks pretty fresh [22:05:17] but closeups of the wood and surrounds would be nice [22:05:44] LAT : 55.928366 , LON : -152.919731 , DEPTH : 2976.1373 m, TEMP : 1.56721 C, SAL : 34.64974 PSU, DO : 3.3627 mg/l, TURBIDITY : 0.9341 FTU [22:05:58] can we get another angle on the crab? [22:06:37] Barnacle shells? [22:06:48]
