Hooper SL. Octopus movement: push right, go left. Curr Biol. 2015;25(9):R366-8.
Octopus arms have essentially infinite degrees of freedom. New research shows that, despite this potentially great complexity, to locomote octopuses simply elongate one or more arms, thus pushing the body in the opposite direction, and do so without activating the arms in an ordered pattern.
