Cameras at the bottom of the Tonga Trench in the South Pacific have captured rare footage of a bigfin squid with spindly arms that stretch several feet long, a new video shows.
Bigfin squid (Magnapinna) are an extremely elusive type of cephalopod — a group that also includes octopus and cuttlefish — with only around a dozen sightings on record. They are the deepest-dwelling species of squid known to science, surviving at depths of more than 20,000 feet (6,100 meters), according to the Ocean Conservancy.
