6. Dumbo Octopus By: Rory Cole The Dumbo octopus or Grimpoteuthis is one of the rarest species of octopus. They move by jet propulsion, using their eight arms, and, or moving their elephant-earl-like-flaps. By using all of these different methods of movement, the Dumbo octopus can hover or swim. They eat copepods bivalves and crustaceans. An interesting fact about Dumbo octopi is that they eat their prey whole. This kind of octopus can dive farther than any other octopus. They are seen most frequently at depths of 3,000-4,000 meters below sea level, but have been seen up 7,000 meters below sea level. Beccary, . "Dumbo Octopus with elephant ears." Nature's Crusaders .
