"Dumbo octopus&qquot; Grimpoteuthis bathynectes swims in the Northeast Pacific Ocean; image courtesy of University of Washington/YouTube Down in the dark depths of the deep ocean live more than a dozen species of "Dumbo" octopuses.These octopods from the genus Grimpoteuthis are so named for their prominent, unusual earlike fins that they use to help them swim (reminiscent of the Disney elephant character who used his ears to fly).
