This M’sian snake cartwheels its way to safety at surprising speed

When danger approaches, most snakes rely on their ability to slither swiftly into hiding. But a remarkable group of small reptiles found in Malaysia has developed an escape technique that would put any accomplished gymnast to shame.

Rather than gliding across the ground, dwarf reed snakes can curl their bodies into a wheel-like shape and propel themselves forward in a succession of rapid cartwheels.

Now, an international team of scientists studying these elusive creatures in Borneo has discovered how they accomplish this extraordinary manoeuvre, reaching speeds of more than 13km/h while keeping their heads remarkably steady.

The findings, published in the journal “Current Biology”, shed new light on one of the animal kingdom’s most unusual forms of movement. Led by researchers from Japan’s Toho University, the study examined three species of dwarf reed snakes belonging to the genus “Pseudorabdion”, including one named “Pseudorabdion saravacense”.

The team recorded the snakes from multiple angles during experiments conducted in East Malaysia in 2019 and 2022, analysing precisely how different sections of their bodies moved during each rotation.

They discovered that the snakes achieved peak speeds of between 1.72m and 3.69m per second while rolling, approximately four times faster than when moving through conventional sideways undulations.

What makes the feat particularly impressive is the reptiles’ ability to maintain control despite moving at such speeds. Even while cartwheeling, they successfully navigated a narrow track measuring just 20cm across.

Ordinarily, a rotating body presents a considerable challenge for any animal. Without the axle of a wheel, the head would be expected to rotate alongside the rest of the body, disrupting the creature’s ability to see where it is going.

The dwarf reed snake, however, has evolved an ingenious workaround. Rather than spinning its entire body indiscriminately, it coordinates successive movements of its front and rear sections.

The posterior portion rotates rapidly while the head remains elevated, relatively stable and directed towards the intended escape route.

This remarkable separation of movements allows the snake to combine speed with directional control, potentially giving it a valuable advantage when fleeing predators.

Malaysia’s extraordinary serpents

The discovery adds another fascinating chapter to Malaysia’s rich reptilian diversity, which extends well beyond the familiar cobras and pythons. In July, wildlife enthusiast Vincent Teo highlighted several species with equally surprising adaptations.

The elusive dragon snake, for instance, can become rigid when disturbed, relying on its unusual appearance and camouflage to escape attention. The blunt-headed slug snake uses specialised teeth to extract snails from their shells, while the radiated rat snake has been observed feigning death to deceive potential threats.

Together, these behaviours demonstrate how different species have evolved remarkably varied strategies for feeding, protection and survival.

The dwarf reed snake’s cartwheeling ability was first documented scientifically in 2023, but the precise mechanics behind the movement had remained largely unexplained.

The latest investigation, which includes Malaysian researchers Yazid Hossman and Clement Het Kaliang, provides a clearer understanding of how an animal without limbs can achieve such sophisticated rotational movement.

It also challenges assumptions about the physical limitations imposed by an animal’s anatomy. The researchers believe the findings could have wider implications for understanding animal locomotion and the relationship between physical structure and behaviour.

For now, the dwarf reed snake offers an extraordinary reminder that nature’s most ingenious adaptations are not necessarily found in its largest or most conspicuous creatures. Sometimes, they belong to a tiny snake whose best chance of survival is to curl up and roll away.
