Apparently, according to Scientific American, Octopi can fly. Numerous anecdotal accounts, including those by marine scientists, suggest that in predator avoidance an octopus can fire it's jets and leap right out of the water. Obviously rare, there's no YouTube video (except octopi balloons and kites). Witnesses claim to have observed the animal adjusting it's fins (some species) and mantel for "English" to maneuver. Octoflight has been visually estimated as at much as 3 meters high and 30 meters in duration.
