Quattrini et al 2017 Deep Sea Research showed a picture of this fish and called it Polyepion sp. A, possibly a new species. [17:42:22] range so far is 363m-410 [17:42:50] danielwagner leaves the room [17:43:06] looks like a black coral to me [17:44:04] Maybe Ellisellidae [17:44:17] take that back on the close up [17:44:47] There are several whip-like forms in that family, and they get more common the shallower you go. [17:45:11] danielwagner leaves the room [17:45:37] Note on feeding of the large white gorgonocephalan basket star seen perched atop large sponge: considered to be suspension feeders - BUT when open this large sticky surface functions as a fish trap for very small midwater fishes swimming over the substrate at night. Any fish touching the basket star gets glued tight and when many are so secured, the basketstar closes up into a tight ball - presumably digesting its victims. Have seen this several times. Think they are not primarily suspension feeders, but nekton predators. They can also move rather fast. We deployed large fish traps at 300 m depth - next day basketstars on the trap with a few inside - attracted to cut fish bait [17:46:00] LAT : 18.207183 , LON : -67.803442 , DEPTH : 392.6972 m, TEMP : 14.75689 C, SAL : 35.97379 PSU, DO : 4.8515 mg/l [17:47:49] @Ken: that is very interesting. Not sure how they would begin digestion in the pocket you describe as the mouth is oriented downwards, but never underestimate the power of adaptation when it comes to using new food sources.

[17:49:51] michellescharer leaves the room [17:50:06] danielwagner leaves the room [17:50:18] Scott - well, I do not know much about echinos. But when they ball up, the ball is very tight. I had assumed the digestive area would be within the ball. You see both open and closed individuals at the same time, but many more are fully open at night [17:50:36] @Ken: unless the tight ball has the arms curled downward! Then it totally works.

Name?? It looks like a serranid bass/basslet, but the small mouth is wrasse-like, not serranid like (long gape). This fish also swims partly by oaring the pectoral fins in coordination - again wrasse-like [18:02:17] danielwagner leaves the room [18:02:56] @ken it is a wrasse Polylepion sp. [18:03:37] Thanks stacey - new to me, have not seen this fish in deep water in Gulf of Mexico [18:04:13] danielwagner leaves the room [18:04:17] My impression is the black corals are the dominant fauna today, or at least the dominant corals, especially the feathery ?Antipathes.

They have very weird delta 13C values, not in the typical range for suspension feeders consuming plankton or fresh particulates. I have wondered how some of these BCs could feed effectively on plankton - the polyps being miniscule and/or enclosed. 13C values suggest specialization of highly refractory carbon - perhaps recycled by resuspension of bottom sediment carbon?? Deep-water sponges have similar, equally weird values. I think Amanda D has perhaps gotten additional stable C data on BCs. Need to run 34S at same time to gain insight [18:11:33] danielwagner leaves the room [18:12:13] jasonchaytor leaves the room [18:14:44] @Ken: I can add that I've never seen a black coral polyp holding some presumptive prey. In fact, that is the case for most of the deep water corals we observe on video. Guess we'd need to train a camera on the colony for a very long period of time. So, it wouldn't surprise me at all to learn our assumption that they are all plankton predators is off. Just like the discovery of how vampyroteuthids feed - fearsome grazers of marine snow!
