This fish, known since 1899, had never been captured on film until now. Aug. 29, 2012 -- This fish is extremely rare and has never been captured on film before. The Chaunacaops coloratus anglerfish was described in 1899 from a dead specimen, but has never even been filmed alive until now. The deep-sea fish was filmed by the Monterey Bay Aquarium Research Institute (MBARI) using a remote operated vehicle (ROV) 7,500-11,000 feet below the surface of the ocean off the coast of northern California. MBARI captured the 8-inch-long anglerfish and learned much about its behavior and habits, the institute said in a press release.
