This video from the USA says about itself:
This video shows never-before seen footage of a deep-sea angler fish, Chaunacops coloratus. In it, we summarize recent work by scientists at Monterey Bay Aquarium Research Institute, Moss Landing Marine Laboratories, and Monterey Bay National Marine Sanctuary. The video seen here was recorded by MBARI’s ROV Doc Ricketts at depths of 7,800 – 10,800 feet below the ocean’s surface.
