Snake locomotion (2)

The video explores how snakes move without legs, focusing on the role of their scales. Initially thought to push off rocks, new research shows that the overlapping scales create friction that propels them forward. Experiments with a special jacket demonstrate the importance of scale directionality. Mathematical models incorporating weight redistribution further explain snake movement, drawing parallels to legged animals. The video concludes with unique challenges faced in snake research, highlighting the intersection of math and biology.
