Dumbo Octopus Grimpoteuthis plena

Little is known about the Dumbo octopus, as only a few have been recorded. Its common name derives from a pair of unusual, earlike flaps extending from the mantle above its eyes. The Dumbo octopus has a soft body, an adaptation to its deep-water habitat, and eight arms connected to each other almost to their tips by “webbing.” Its diet includes worms and snails.
