I'm a research assistant at the Medical University of South Carolina also in Charleston and soon will be moving to Georgia Tech to start a PhD. I am interested in the chemistry that marine critters produce (called secondary metabolites or natural products) and their ecologcial purposes and the potential uses for human therapeutics. I used to be down at the Harbor Branch Oceanographic Institute and have worked there with Shirley Pomponi and Amy Wright.

Its common that glass sponges (normally colorless) will adopt a yellow color.

[15:48:25] Re: Enrique comment that the matrix appears to be mostly Madrpora- This would be highly unusual in this region. The various mounds are usually primarily Lophelia and Enallopsamia, and sparse Madrepora. Off Miami region Enallopsammia is more prevalent,. [15:49:28] Thanks! Very happy to be following along [15:49:50] Gray fish with black fin margins = cusk eel, Ophidiidae, looks like genus Monomitopus, probably M. agassizi. Parasite attached midbody on lateral line.

[16:19:03] Cheryl - you are correct, nettastomid eels are called duckbill eels or sorcerer eels [16:19:52] @Amy when were you at TAMUG? [16:19:56] Mushroom coral [16:20:21] Cool! Thanks Ken! Hope you are well! [16:20:52] cladorhizid? [16:21:14] Can we sample a specimen of the white octocoral? [16:21:40] Nettastomid with black tail is probably in the genus Nettastoma [16:22:04] We think it might be a swiftia and would love a collection of this white octocoral at some point [16:22:41] LAT : 28.249284 , LON : -79.598549 , DEPTH : 771.1618 m, TEMP : 7.0977 C, SAL : 34.91583 PSU, DO : 4.19096 mg/l [16:23:25] We believe that the white spiny puffballs are a type of demosponge [16:23:38] So much diversity in that tiny rubble patch! [16:26:06] Live Lophelia thickets can sometimes be essentially a low-diversity monoculture, but the Lophelia patches offer an ecotone interface, supporting greater diversity [16:26:28] @nolan I think they might have been cladorhizids, which are carnivorous sponges [16:26:50] I think some of the larger globous sponges (some have been yellow) could actually be Heterorete sp. which is in a different family then Farrea [16:27:17] Alexis Weinnig leaves the room [16:27:42] LAT : 28.249101 , LON : -79.598484 , DEPTH : 764.8454 m, TEMP : 7.10268 C, SAL : 34.91492 PSU, DO : 4.1943 mg/l [16:27:49] @Tara Oh yes! I remember now, that's the conclusion we came to in the past, I just couldn't quite remember just now.

[16:28:47] @nolan I agree! [16:28:51] i was leaning towards Enallopsamia [16:30:41] Last eel with black caudal fin area and silver belly is a juvenile Synaphobranchus, either S. kaupi or S. affinis - both co-occur at this depth [16:31:43] Gotta go work in the lab, I'll stay logged into the chat and occasionally read it.

As per Edie Widder's intriguing research, I suspect that animals like the large yellow sponge seen frequently here is either bioluminescent and/or fluorescent.
