Bigfin Squid: Genus Magnapinna

On November 9, 2021, during Dive 10 of Windows to the Deep 2021, NOAA Ocean Exploration captured remarkable footage of an adult bigfin squid, genus Magnapinna. While we did not get a length estimate on this squid, the largest bigfin reported was about 6.4 meters (21 feet) in total length (including the arms and tentacles). Bigfin squid are the deepest known squids and while sightings of them have been recorded globally, the total number of sightings is likely less than two dozen, making this observation rare and all the more exciting.
