This video will have one of two effects: It will either delight you or make you afraid to go to sleep. After all, the deep-sea angler fish is the stuff of nightmares. With its garish teeth and disconcerting body shape (it's basically a giant mouth with a few fins tacked on) - not to mention it lives at an ocean depth where it's always pitch dark - you'd be forgiven for wanting nothing to do with the deep-sea anglerfish.

And yet, this video is so entrancing that it's virtually impossible to not be entranced by the fish.

According to the videographers, this little angler is about 9 cm long and is named Melanocetus.

"It is also known as the Black Seadevil and it lives in the deep dark waters of the Monterey Canyon. MBARI's ROV Doc Ricketts observed this anglerfish for the first time at 600 m on a midwater research expedition in November 2014. We believe that this is the first video footage ever made of this species alive and at depth."
