Rolling snakes reportedly stabilize their heads while the rear body spins

The head stays aligned while the rear body rotates

Researchers from Toho University, Hokkaido University and Kyoto University and their collaborators reported analyzing the rolling-like movement of naked cat snakes. They found that, while the rear portion of the body rotates substantially, the head remains oriented in the direction of travel and relatively stable in height. The article says the highest rolling speed reached about four times that of ordinary serpentine locomotion and that the snakes moved stably along a narrow racetrack.

The supplied material compares the rolling motion’s top speed with ordinary serpentine locomotion, but does not establish a broader before-and-after baseline for this behavior.

The reported video analysis links fast, controlled rolling to rear-body rotation paired with stabilization of the head’s direction and height.

The observation reportedly identifies a form of body control that lets an animal maintain a stable head while much of its body rotates, connecting that control with fast and directed movement.
