what is a dumbo octopus

The dumbo octopus is a deep-sea umbrella octopus, noted for its fins that resemble Dumbo the elephants ears. The name "dumbo" refers not just to one species but to an entire genus of at least 15 species of dumbo octopuses. They have a semi-translucent body with an internal "U" or "V" cartilaginous shell or mantle, which gives them some shape. They move by slowly flapping their ear-like fins, and they use their arms to steer. They are foraging predators and eat pelagic invertebrates that swim above the sea floor. Dumbo octopuses live at extreme depths in oceans around the world, up to 13,000 feet below the surface, and are the deepest-living octopuses known. They are small animals, around 8 inches tall, and have a pair of fins located on their mantle, their namesake, and webbing between their arms. Due to their preference for extreme depths, they are only very rarely captured in fishing nets and are probably not threatened by human activities.
