The bigfin squid is the deepest dwelling squid in the entire ocean, having been filmed at an incredible depth of 6,000 meters. This alien-looking creature is also the size of an orca, has no suckers, and its tentacles jut out like "elbows". Bigfins are very rare and unique cephalopods, with much still unknown about how they hunt or reproduce. Finding and studying these deep living creatures is difficult, but important.
