by Flapjack octopuses usually appear pinkish.
They have fins above their eyes, similar to those found on some species of squid.
Their maximum size is 20 cm (7.9 in) mantle length.
They have eight arms (like any other octopus), but these affixed together in an umbrella shape.
However unlike other octopus, they are unable to camouflage by changing skin color and texture.
They have a gelatinous body, which spreads into a parachute shape when maneuvering through dimly lit water.
They swim by moving their fins, pulsing their webbed arms, pushing water through their funnel for jet propulsion, or all three at once
