The marine photographer who captured the footage said it could be the world's first recorded sighting of a black seadevil alive in broad daylight near the ocean surface.

Researchers from the NGO Condrik Tenerife have captured what they say are the first images of an adult black seadevil anglerfish, also known by its scientific name Melanocetus johnsonii, alive near the ocean’s surface.

Marine researchers were out looking sharks off the Canary Islands when they found something quite unexpected -- a humpback angler fish known as a "black sea monster." It was the only known sighting of the deep-sea fish on the surface of the ocean.
