Snakes can exhibit 5 different modes of terrestrial locomotion: (1) lateral undulation, (2) sidewinding, (3) concertina, (4) rectilinear, and (5) slide-pushing. Lateral undulation closely resembles the simple undulatory motion observed in many other animals such as in lizards, eels and fish, in which waves of lateral bending propagate down the ...
Sidewinding in a newborn sidewinder rattlesnake. Yellow regions are lifted above the sand and in motion at the time of the photo, while green regions are in static contact with the sand. 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]

The function of these folds is to permit the circumference of the snake to increase, allowing prey to pass into the stomach during feeling.
