A rare black seadevil was captured for the first time on video in Monterey Canyon, and it’s a weird creature. The canyon plunges to a depth of nearly 3 miles — or 14,763 feet. The creature was caught alive on camera at about 1,900 feet. The fish, also known as a deep-sea anglerfish, is about 3.5 inches long. They die when brought to the surface. Anglerfish don’t have a swim bladder, so, unlike some other deep-sea animals, they won’t have all of their organs pushed out of their mouth when they’re brought up. The difference in pressure (and temperature, amongst other things) still kills them.
