Researchers show how dwarf reed snakes escape from predators.
Researchers have uncovered surprising new insights into a species of snake that escapes danger by rolling at high speed.
The study, led by Toho University in Japan, found that dwarf reed snakes use precisely coordinated body movements to keep their heads stable while the rest of their body rotates rapidly.
Native to Southeast Asia, dwarf reed snakes are among the few animals known to roll away from potential predators. However, until now, little was known about how they actually achieved this movement.
To investigate, researchers recorded multi-angle video footage of the snakes in motion and analysed their mechanics in detail.
Reporting in Current Biology, the team revealed that the snakes do not simply rotate their bodies as a single rigid unit. Instead, each cycle consists of a continuous sequence where the snake rolls with one side against the ground, then swings an arched section of its body past its head toward the ground - a motion the researchers termed a “stroke.”
Additionally, they found that the snake’s head remains aligned with its direction of travel rather than spinning along with its body. Its head also stays relatively level, especially during high-speed rolling when the snake keeps its head elevated to reduce vertical head movements.
The researchers believe this combination of rapid body rotation and head stabilisation allows the snakes to maintain control and visual awareness while making a speedy getaway.
