The dozen or so species that make up Grimpoteuthis are called Dumbo Octopuses because of the two large fins – One on either side of the mantle – That protrude like ears.
Add in the octopus’s small size (generally around eight inches), relatively short arms, bell-shaped body, pale coloring, and tendency to hover over the seafloor, and you’ve got a cephalopod that’s often called the cutest octopus in the world.
