Remarkable Living Worm Structure Could Pass for an Unconventional Escape Vehicle
Worming Together: A Natural Phenomenon Uncovered
When the time is due, these humble worms unite to form a wriggling colossus, a testament to unity we've never seen before. We're talking about towers of worms, and yes, they're as fascinating as they sound. They clamber upon each other, creating one interconnected organism, ready to explore and adapt to their surroundings for up to 12 hours.
But why do they do it?
A Towering Achievement: Delving into the Worm's World
"When I first saw those natural towers, I was thrilled," says Serena Ding, group leader at MPI-AB. "For ages, we've only imagined worm towers in our dreams. But with diligence and determination, we discovered these structures hidden among us."
Scientists have always speculated that worms might construct such structures, and now they've finally proven it. Nematodes possess an astonishing array of behaviors, some thriving even under extreme conditions like freezing temperatures or Chernobyl radiation. They can taste sunshine and transform plants into zombies. But worm towers eluded them- until now.
Collective Dispersal: A Shared Experience
Building worm towers is reminiscent of a unique phenomenon known as collective dispersal. Only a few animals, like slime molds, fire ants, and spider mites, have displayed such behavior in the past. However, unlike these creatures, worm towers consist of identical individuals, or clones, indicating a harmonious lack of competition. There's no hierarchy, no choreography, and yet the result is harmonious and graceful.
On the Hunt: Investigating the Tower-Builders
Researchers observed towers forming on decomposing apples and pears, and they found that these structures harbored two species of Caenorhabditis worms. These particular worms often enter a stress-resistant phase called the "dauer" stage, helping them endure harsh conditions. It's these dauers that construct and congregate in the towers.

Discovering the Tower Secrets:
Long hours with a digital microscope and a passion for discovery led Ryan Greenway to unearth worm towers in orchards near the university. In the lab, some of these structures were recreated using toothbrush bristles, allowing for further investigation and analysis.
The results were astounding. Tower height could reach an impressive centimeter, and the structures could realign themselves and stretch across gaps. When gently touched, the towers would extend towards the stimulus, and dozens of worms would sometimes migrate en masse to a new food source.
Innovation in Motion:
"A tower of worms is not just a pile of creatures," explains Daniela Perez, a postdoctoral researcher at MPI-AB. "It's a living, breathing, coordinated structure that responds to its environment."
Perez goes on to say, "The tower is growing and responding to stimuli. Touching it causes it to extend in the direction of the touch, anchoring to the new surface."
Furthermore, individual worms in the tower are interchangeable, with no discernible differences between the base and the top. Researchers, however, note that this might change in various situations.
A Mystery Unfolding
Although much has been learned about the tower phenomenon, many questions remain unanswered. For instance, how do the worms synchronize without a leader or signals? What sensory cues trigger tower formation? Why don't the non-dauer worms tower? And what roles do individual worms play in different genetic groups?
For now, towers of worms remain one of nature's enigmatic wonders, a silent dance between life forms that continues to unfold despite our curiosity. The fact that such complexity and purpose can emerge from a mass of clone organisms demonstrates the power of evolution, capable of constructing marvels with no blueprints, only pressure, time, and a burning will to scale new heights.
