This dumbo octopus was filmed at a depth of 900 meters (2,950 feet) using the Global Explorer remotely operated vehicle. There are six families of finned deep-sea octopods which all belong to the Cirrata suborder. Cirrate octopods differ from other octopods in that they have all but abandoned swimming via jet propulsion and instead they rely on fins as their primary means of locomotion. These ear-like fins that protrude just above the eyes has earned this group the nickname "dumbo octopods," in honor of the ears of the famous Disney elephant, Dumbo.
