hello, i find distinguishing the different cranchids nearly impossible, here's a bunch from various dives that i don't think have been identified beyond the family level. first up is a short clip from the rebikoff foundation. they mostly dive around the azores so far as i know, so it'd be central atlantic. not sure what depth, but probably < 1000m since i think that's the max depth for their sub.

In the last one, the video is slightly grainy, but that tuft above the eyes does appear to be a cluster of tentacles... it's amazing how it seems to use the tentacle clubs (or something) as a kind of lure like the angler fish... amazing stuff. I've grabbed a moment where the cluster seems to dissipate and you can see the tentacles themselves:

here's another one i'm not sure about, near the great barrier reef. asked fernando fernandez-alvarez and his guess was most likely teuthowenia but couldn't confirm a genus from the footage. (yes, this occurs in the same segment as the ram's horn squid observation)
