Provided that they're muscles, it can be noted that this means the octopus need to actively flex the longitudinal muscles in the course of jetting in an effort to keep the mantle at a constant length. The radial muscles operate perpendicular into the longitudinal muscles and they are used to thicken and thin the wall of the mantle.
