This is only the second time the species has been recorded while alive. “I thought it was A.I.,” says fish biologist Kory Evans.

While on a shark research expedition off the coast of Tenerife, marine biologists said they captured the first images of an adult black seadevil anglerfish 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.
