A study co-authored by University of Cincinnati Professor Bruce Jayne, an expert in snake locomotion, has revealed the secret behind how snakes can stand upright without arms or legs. The research, published in the Journal of The Royal Society Interface, combines biology, mathematics, and mechanical modeling to explain that snakes don't have to stiffen their entire bodies to span gaps or reach up to branches - instead, they use their powerful muscles to maintain balance at the base where their weight is supported.

Why it matters

Understanding the unique abilities of snakes to navigate complex environments has broad scientific implications, from improving robotics and engineering to shedding light on evolutionary adaptations. Jayne's previous work has uncovered other remarkable snake locomotion techniques, making this latest discovery an important addition to our knowledge of these fascinating reptiles.

The details

The study found that snakes can stand upright by using their muscles to become rigid near the base of their bodies, where their weight is supported, rather than stiffening the entire length. This allows them to stretch up or outward while maintaining balance, a key to their ability to span gaps in forests or reach up to branches and ledges.

  • The study was published in the Journal of The Royal Society Interface in March 2026.
