This video is dang interesting to me, and perhaps is even must see. the Angler Fish is famous. It is the iconic deep sea fish and versions of it are use everywhere in science fiction, fantasy, and horror - I'm a nature nerd - yet, even I have never seen the Angler fish 'portrayed' this way: I knew nothing about its jellyfishlike "catwhiskers" : it's just amazing..
(mating thing is not focus of video)
This better be happening.
