Psolus! [21:42:57] LAT : 48.154828 , LON : -125.816777 , DEPTH : 910.5014 m, TEMP : 3.67815 C, SAL : 34.34925 PSU, DO : 0.39313 mg/l, TURBIDITY : 2.0208 FTU [21:43:01] psolidae [21:43:19] Solace [21:43:22] There is the Psolus...just a bit shallower than yesterday [21:43:26] yes [21:43:32] @jenna, nice idea--i wonder which species meredith might recommend we look at for that...lophelia or desmophyllum versus ? [21:43:43] yes.. like bottom of a shoe [21:43:48] the one on the right is also Psolus [21:43:52] The tentacles retract [21:44:24] (a closed one) [21:44:55] I would argue another sea cucumber just closed [21:44:59] the dendrochirote holo are most diverse in shallow water [21:45:00] there is a squat lobster to zoom on...didn't you ask for one? [21:47:56] ?? which one? [21:47:58] LAT : 48.154831 , LON : -125.816796 , DEPTH : 909.4827 m, TEMP : 3.63984 C, SAL : 34.36367 PSU, DO : 0.35156 mg/l, TURBIDITY : 2.0574 FTU [21:48:07] ah.. [21:49:33] hiding brittle star! [21:49:50] emilycahoon leaves the room [21:49:50] I do not think sponge. Possibly tunicate? [21:49:53] strange thing. maybe we can slurp it [21:50:06] tunicate [21:50:14] could it be a crashed siphonophore? [21:50:21] cool [21:51:24] thats the Tretodictyidae! [21:51:34] slurp away [21:51:44] its hard but very brittle [21:51:52] It might be a little bit to crunchy/crusty to slurp. [21:52:05] if you knock a piece off and slurp [21:52:12] that might work well [21:52:34] that bit on the right looks promising [21:52:57] LAT : 48.154815 , LON : -125.816879 , DEPTH : 909.6806 m, TEMP : 3.6349 C, SAL : 34.36479 PSU, DO : 0.33131 mg/l, TURBIDITY : 2.558 FTU [21:53:08] will small bits in the slurp be okay? They are on a pretty steep slope so if it falls they won't go collect it off the sediment (just for awareness) [21:53:36] hmmm [21:54:01] small bits would be ok [21:54:18]
