The Dumbo octopus is named after Disney’s Dumbo the elephant character, from the eponymous movie, that was famous for its big ears.
Unlike most octopuses, the Dumbo octopus doesn’t have an ink sac because it rarely encounters predators in the deep sea.
The Dumbo octopus uses its ear-like fins to propel through the water and steers using its webbed arms.1
The Dumbo octopus is the deepest-living genus of all known octopuses.
