Opisthoteuthis californiana, also known as the flapjack octopus, is a species of umbrella octopus.
The flapback octopus usually appears as transparent to dark red. Their maximum size is 20 centimetres (7.9 in) mantle length. They have eight jointed legs which are affixed together in an umbrella shape. They have a gelatinous body, which spreads into a parachute shape when maneuvering through dimly lit water. The flapjack preys on small fishes and planktonic crustaceans. They swim by moving their fins, pulsing their webbed arms, pushing water through their funnel for jet propulsion, or all three at once. Their depth range is: Para-larvae 200 metres (660 ft), adults 500–1,500 metres (1,600–4,900 ft). (from Wikipedia)
