The net cost of transport (NCT), which indicates the amount of energy required to move a unit of mass a given distance, for a snake moving with a lateral undulatory gait is identical to that of a limbed lizard with the same mass. However, a snake utilizing concertina locomotion produces a much higher net cost of transport, while sidewinding ...

Blue denotes tracks. Scale imprints are visible in the tracks, showing that the snake's body is static during ground contact. Tracks of a sidewinder in the sand.
Rectilinear locomotion relies upon two opposing muscles, the costocutaneous inferior and superior, which are present on every rib and connect the ribs to the skin. [5] [6] Although it was originally believed that the ribs moved in a "walking" pattern during rectilinear movement, studies have shown that the ribs themselves do not move, only the muscles and the skin move to produce forward ...
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. [1] [2] It is named after the concertina musical instrument. [citation needed]
