Umbrella octopi are known for their curious way of getting around – by using a combination of pulsing their webbed arms, moving their fins, and jet propulsion through a funnel, some compare it to a parachute being unveiled. Little is known about the Opisthoteuthis, except that it resides in the mesopelagic zone – up to 500 meters below the surface of the ocean. Specimens average ~7 inches in diameter.
