Interesting [16:56:47] I believe the large ones are sprem contining ones [16:56:57] The little ones might have eggs [16:57:15] The large ones contain spematophores [16:57:27] Let me get the reference [16:57:56] The swollen balls at the tip of the sponge’s upright branches produce packets of sperm. These sperm packets are released into passing currents and are captured on the branches of other nearby sponges. The sperm then works its way from the packets into the host sponge to fertilize its eggs. As the fertilized eggs mature, these contact sites swell up, forming bulges part way up the host sponge’s branches [16:58:22] Lee, W. L., Reiswig, H. M., Austin, W. C. and Lundsten, L.

This sponge seems to have a very flexible morphology. The similarity is in the oscula. [17:34:26] I think it is useful to check on the blue sponges in the future once we get an ID for this one. There is another blue sponge in the family Desmacellidae but is much more of an encruster and has different oscula.

[18:38:47] Depends on what else you want to see and how to use the time. [18:39:14] @CrisDiaz Has an ID so I am not sure about the sponge. Do we know the range of the sponge? [18:39:22] I would have simply pulled up the sponge from the sediment and hoped the squat lobster held on. [18:39:41] I think Scott, if Tim has seen this, then we should not collect [18:39:47] Looked like the goblet was spitting a fireball [18:40:09] The one I have here is not from GoMex or off Florida [18:40:15] LAT : 23.969945 , LON : -81.800269 , DEPTH : 1116.8632 m, TEMP : 4.45385 C, SAL : 35.86392 PSU, DO : 6.50195 mg/l, TURBIDITY : 0.9035 FTU [18:40:26] stepping away for a bit [18:40:39] I'm only saying I have shared with him zoanthids from a Hyalonema stalk.

The Hyalonema/zonathids I have ARE from GoMex [18:41:51] Sittinghere with it in my hands now!

[18:47:23] More on the sponge sitting in front of me... It was collected from northern GoMex at about 1170 m depth, so pretty close to where we are now. I'll definitely send it to NMNH so you have both it and the zoanthids. [18:47:37] christophermah leaves the room [18:47:43] @Stephanie Just curious because I stepped away. An awesome collection! Y'all are going to have a great evening with all the subspecimens! [18:47:52] And I verified: Tim did subsample it - back in 2012! [18:47:59] @Scott! Nice. [18:48:11] Wooo yeah sequence the genome! [18:48:52] We stole its spongey treasure [18:48:57] So what did I miss as I was doing all this typing and searching? Did we collect the squat lobster? The sponge/zoanthids? [18:49:01] We got funds for a few from this cruise. [18:49:04] That would be great. I said cf. conqueros, there are few differences, but yiur work will nail it [18:49:30] @Scott, all got sucked up at once. Unclear if Squat made it to destination bucket. [18:49:40] @Scott Definitely zooanthids, maybe the squat lobster and maybe the hermit crab. [18:49:44] @Allen: thanks.

[19:04:18] feather stars are Atelecrinus.. .or at least Atelecrinidae.... they have those bare tips [19:05:18] LAT : 23.970018 , LON : -81.800161 , DEPTH : 1114.9543 m, TEMP : 4.47658 C, SAL : 35.89954 PSU, DO : 6.46113 mg/l, TURBIDITY : 0.9524 FTU [19:05:52] Chirostylidae, Uroptychus [19:06:14] Thanks for spelling Scott! [19:07:24] Purple almost looks like "Royal Purple"! [19:08:41] stephaniefarrington leaves the room [19:10:03] @Kevin: that is how I refer to them: the royal purple octocoral. [19:10:18] LAT : 23.969974 , LON : -81.800218 , DEPTH : 1115.5481 m, TEMP : 4.47834 C, SAL : 35.9013 PSU, DO : 6.43392 mg/l, TURBIDITY : 0.8974 FTU [19:10:33] Much of what I know of the chirostylids comes from Kareen Schnbel. Here is something from one of her papers: "Chirostylidae are often found to be host-associated with other marine invertebrates such as pennatulaceans gorgonaceans, and antipatharians (Baba, 1974; Baba & Haig, 1990; Rice & Miller, 1991), which in turn are mostly limited to the steep rocky slopes of the seamounts, ridges, and continental margins. This may provide an additional limiting factor for wide distributions and high species densities across large distances" [19:10:42] @Scott...nice! [19:11:02] I like the sounds of that. The royal purple octocoral. [19:12:24] solenosmilia [19:12:44] solenosmilia [19:13:30] Thanks guys. I was one l off [19:14:20] I proudly wear the fool hat in this context.

An aplacophoran? [19:17:35] stephaniefarrington leaves the room [19:17:42] Don't put the coral back now! [19:17:52] I thought I saw it swimmingh in the bucket. [19:18:22] It swam out of bucket. :( [19:18:54] They are going to do much better than they would have if they had stayed in the bucket!
