The name dumbo octopus refers not just to one species but to an entire genus of deep-sea umbrella octopuses, noted for their fins that resemble Dumbo the elephantβs ears (of Disney fame).
There are at least 15 species of dumbo octopuses, and like all umbrella octopuses, their arms are connected by a web of skin, causing them to resemble umbrellas when their arms are spread apart.
