But I have also seen look alikes or members that I do not recognize as Geodias (I am most definitely not an expert on them). As for the blue sponge, if you can collect a geological sample that has it on it, thats fine. It would be interesting to catalogue it and get a potential ID from it. But its not a priority.

[15:40:25] @WatchLeads I will be in and out today. I will try to stay on top of sponge IDs as I can. But if you see some sponges that you think are in the ASPIRE List, most of them are in the animal guide. Pheronematidae have furry or fuzzy (called lophophytous) attachments to ususally hard substrate. Aphrocallistes has a characteristic shape. There are some very good images in the animal guide for these two groups. Vazella are Euplectellid vases that are fairly dense, squat, and very spiny so that they collect a lot of marine snow (not in the guide). The Geodias may be sort of hit or miss because they are pretty much characterized by being relatively tough/crunchy due to high content of siliceous spicules, but have an extremely variable general morphology. [15:40:30] Cladorhizid sponge [15:42:35] This is a hyalonematidae glass sponge [15:42:42] thank you [15:43:14] Stalk sponge is Hyalonematidae [15:43:25] LAT : 18.015843 , LON : -65.72947 , DEPTH : 747.2786 m, TEMP : 7.71244 C, SAL : 34.95691 PSU, DO : 3.99783 mg/l [15:43:41] D'Oh!

Fishes: blue-silver drifting midwater fish with large eye and prominent scales = Neoscopelus; 2 different congrid eels encountered, probably genus Gnathophis (elongate snout) and genus Rhechias (abrupt snout). Need to zoom in on head as was done for first specimen to enable firm ID; reticulated small angler = Lophioides reticulatus; grayish, semi-translucent brotulid = a species of Bythididae - but unknown and maybe undescribed. This is very deep for this type of 'cave brotulid'. Halosaur did have small scales on head = genus Halosaurus. Two macrourids seen nosing along the bottom were Nezumia aequalis. Tripodfish was a juvenile of Bathypterois viridensis - the upright pectoral 'sails' are jet black in adults. Drifting elongate black midwater fish was probably Gonostoma. [16:13:21] need to sign off for appointment. suggest taking a bit more time with hovering and sedentary fishes, zoom in, get good head end detail That translucent brotulid is a case in point - unknown to me, very deep for this type of brotulid, need close-up lateral if possible of head and body to enable best possible ID [16:13:34] LAT : 18.016288 , LON : -65.729185 , DEPTH : 708.0254 m, TEMP : 7.95907 C, SAL : 34.97926 PSU, DO : 3.9161 mg/l [16:13:41] @Ken Thanks alot for those details.

For some reason my Chrome browser had turned off Flash (since Friday) so it needed to have the permission reset. Note above the video on the feed is "The Google Chrome web browser may exhibit difficulties with the live stream if you have not enabled the most recent version of the Adobe Flash Player, particularly for Mac users. For optimal performance and lowest latency, upgrade to the most recent version." When I clicked on the hyperlinked "version" a pop-up message appear that asked if I wanted to block Flash or not. I said "Allow" and now my delay is down to 2 seconds. [16:21:45] Went back to look at strange brotulid - you guys did get excellent close-up. Thanks. Nifty image of Bathynomus isopod - disturb the next one and observe how it swims. Some speculation that they sometimes swim upside down and scoot along the substrate - but I have not seen that. Nice close-up imagery of Neoscopelus. Gonostoma was G. elongatum.

They will likely be covered in marine snow and have lots of spciules projecting out from the main body.
