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 ...
Sidewinding is a type of locomotion unique to snakes, used to move across loose or slippery substrates. It is most often used by the Saharan horned viper, Cerastes cerastes , the Mojave sidewinder rattlesnake , Crotalus cerastes , and the Namib desert sidewinding adder, Bitis peringueyi , to move across loose desert sands, and also by ...
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]
Finally the caenophidian snakes use the fast and unusual method of movement known as sidewinding on sand or loose soil. The snake cycles through throwing the front part of its body in the direction of motion and bringing the back part of its body into line crosswise.
