“The dozen or so species that make up Grimpoteuthis are called Dumbo octopuses because of the two large fins—one on either side of the mantle—that protrude like ears,” says @natgeo. This clip from ROV SuBastian shows a great example of how Dumbo Octopuses use the flapping their strong fins to propel themselves through the water, as opposed to the jet propulsion (expelling water forcefully from their siphons) as other octopuses do. Another noticeable difference is that the Dumbo octopus doesn’t h

Dumbo octopuses (Grimpoteuthis spp., also known as “umbrella octopuses”) are known as one of the deepest living species of octopus in the ocean, inhabiting depths of up to 13,000 feet below the surface! You’ll notice this particular species (identified as “Cirroteuthis” by cephalopod expert Janet Voight from the @Negaunee Integrative Research Center), does not use jet propulsion like its cousins. Rather, it flies only by the power of its two headbound fins. Though the IUCN red list certifies thi
