Biologist unlocks mechanics of snake motion

New York TV station highlights UC's discoveries about snake locomotion

WWOR-TV highlighted discoveries by the University of Cincinnati about the unique ways that snakes can move.

The program Science Now features interesting discoveries funded by the National Science Foundation. It profiled the work of UC College of Arts and Sciences Professor Bruce Jayne, who has been unlocking the surprising ways limbless reptiles have conquered oceans, deserts, grasslands, forests and suburbia.

In his biology lab, Jayne has documented in detail the many ways that snakes can move:

  • Rectilinear: The snake contorts its skin to propel the snake forward in a straight line. This is especially easy to observe in heavy-bodied snakes such as pythons.  
  • Lateral undulation: This is the side-to-side movement of snakes as if they were traversing a slalom sometimes called serpentine locomotion.
  • Sidewinding: Common to some rattlesnakes, this locomotion requires the snake to lift much of its body off the ground to propel it in a sideways direction on loose sand or slippery terrain.
  • Concertina: The coiling and uncoiling of snakes like a spring. 
  • Lasso locomotion: The unique way that some climbing snakes such as brown tree snakes can climb wide cylinders by wrapping themselves around them. Jayne discovered and described this unique behavior in a study published in 2021. 

Jayne says there are other variations of these movements that have helped snakes thrive wherever they are found.

This eyeless cavefish grows extra taste buds

August 21, 2024

Research led by Joshua Gross, PhD, in the UC Department of Biological Sciences, revealed the blind cavefish has a similar number of taste buds as surface fish from birth up to the age of 5 months. Then, these taste buds gradually increase in number and start appearing on the head and chin during adulthood, particularly at around 18 months of age.
