Dumbo octopus have a semi-translucent body with an internal “U” or “V” cartilaginous shell or mantle, which gives them some shape. Some Dumbos are short, squat and yellow, while others resemble a sea jelly with one giant, brown, walking shoe. Some have suckers, in addition to spines, on all of their webbed tentacles while others look more like a traditional octopus with the addition of blue or other colored “ears.” Prominent ear-like fins protrude from the mantle just above the almost sightless eyes of the octopus. They have eight webbed tentacles.
