The platyctenids can be found on a number of "hosts" [23:26:13] amandademopoulos leaves the room [23:26:17] LAT :0.80363, LON : -176.67428, DEPTH : 2287.9821m, TEMP : 1.95212C, SAL : 34.65769 PSU, DO : 3.59013 mg/L [23:26:24] I agree, Steve. [23:26:39] Let me know if this is the spo [23:27:03] the one with the longer spicule-projections [23:27:04] Yes, this is the one [23:27:44] I would regard this as a very high priority for collection. The one on the bottom is better, if the center portion is alive. [23:28:32] An oasis!!!! [23:28:53] those are ctenopohres? Ive never seen those before [23:28:56] aplac [23:29:14] is this a target for collection? [23:29:17] Center tube is alive. Let's look at the one below it, with the longer "branches". [23:29:23] @Erik: yes, benthic ctenophores. Search Platyctenida [23:29:47] It would be great to get a better shot of the putative aplacophorans. They don't normally eat sponges. We only know of one in the Antarctic that apparently does. [23:29:50] Great job at explaining this, Steve. Really great job! [23:29:53] yes target for collection. Maybe the bottom one [23:30:10] because I think the ctenophores and the aplacs would be extremely useful for genetics- [23:30:25] The lower one looks like an older version of the top one. [23:30:41] The platyctenids seem to have the same coloration as the hosts as we have also seen on previous dives. Must be a huge undescribed diversity of them out there if you extrapolate.... [23:30:46] I didn't notice the hydroids. That makes sense re: aplacophorans [23:30:47] It's the same, but the branches are longer. So, if the center is alive, I'd suggest collecting the one on the bottom of the screen. [23:31:08]
