[15:33:58] @Jeff Speaking of which, have yall noticed a lot of debris on this exped? [15:34:30] Nolan, it varies from dive to dive. This one we've seen a whole lot, canyon walls are very old material and prone to failure. [15:34:38] Or do you mean human debris? [15:35:01] @Jeff Haha both! Initially human, then bio/geo [15:35:45] There hasn't been a whole ton of human debris, one dive (I believe second) a few pieces. the MPA and the fishing protected area last dive had none.

Common gray cutthroat eel with black caudal area = Synaphobranchus affinis, Large grayish skate with sparse thorns down the midline, buried in substrate, with shark leech attached = probably Amblyraja radiata. Large flatfish = Greenland halibut, Reinhardtius hippoglossoides, one of the more primitive flatfishes [15:42:25] annidaveerle leaves the room [15:42:56] @Ken How would you distinguish between the Greenland and Atlantic Halibut?

Both AH and GH can have pale white spots, so that does not help. But, in the GH the 'left' eye (top eye) lies almost right on the dorsal midline just in front of the dorsal fin, while in AH it lies lower, below the dorsal midline - as in today's fish. Also, looking again at the video, the caudal fin is notably wide - matching AH. [16:03:11] Incomplete migration of the left eye, as in GH, is a primitive feature also found in the genus Psettodes - in which species the eye that ends up on the dorsal midline can be either the left or the right eye [16:06:14] LAT : 40.90448 , LON : -66.501934 , DEPTH : 682.5812 m, TEMP : 5.26162 C, SAL : 35.00515 PSU, DO : 7.44001 mg/l [16:10:02] Thanks @Ken!
