This sea creature may look like some scary 3D animation of an underwater monster, but it's not. It's completely real. What you're looking at is a deep sea anglerfish known as the Black Seadevil. This sea monster's existence shows that sometimes reality is crazier and more twisted than our scariest nightmares.
I mean, damn, this thing is beyond terrifying. Mother Nature and Evolution team up to do some really crazy things. MBARI writes more about the Black Seadevil:
Deep-sea anglerfish are strange and elusive creatures that are very rarely observed in their natural habitat. Fewer than half a dozen have ever been captured on film or video by deep diving research vehicles. This little angler, about 9 cm long, 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.
It's the first time this particular species has been captured on video. Watch it below. Makes you wonder what else is down there.
