Editing Concertina movement (section)

{{Short description|Method of locomotion used by snakes}}

'''Concertina movement''' is the method by which a snake or other organism anchors itself with sections of itself and pulls or pushes with other sections to move in the direction it wants to go. To spring forward a snake may require a rough surface to thrust back against.<ref name="Gray">{{cite journal
