Editing Bigfin squid (section)

=== Anatomy ===
The specimens in the videos looked very distinct from all previously known squids. Uniquely among [[cephalopod]]s, the arms and tentacles were of the same length and looked identical (similar to extinct [[belemnite]]s). The appendages were also held perpendicular to the body, creating the appearance of strange "elbows". Most remarkable was the length of the elastic tentacles, which has been estimated at up to 15–20 times the mantle length. This trait is caused by filament coiling of the tentacles, a trait that is rare among similar species.<ref name="Osterhage2020" /> Estimates based on video evidence put the total length of the largest specimens at {{cvt|8|m|ft|round=5}} or more, with some estimates up to {{cvt|12|m|ft|round=5}}.<ref>{{cite magazine |last=Bolstad |first=Kat |date=May 6, 2003 |title=Deep-Sea Cephalopods: An Introduction and Overview |url=http://www.tonmo.com/science/public/deepseacephs.php |magazine=The Octopus News Magazine Online}}</ref> Viewing close-ups of the body and head, it is apparent that the fins are extremely large, being proportionately nearly as big as those of bigfin squid larvae. While they do appear similar to the larvae, no specimens or samples of the adults have been taken. While their exact identity is unknown, all of the discovered specimens can be observed to have a beige color body, translucent fins, near-white tentacles, and dark eyes.<ref name="Osterhage2020" /> These species of squids are mainly identifiable by their long thin arms and specific colors. The squid also have a very unique brachial crown that sets them aside from the rest of other families that are known.{{sfn|Vecchione|Young|1998|pp=429-437}}
