What’s worse than a giant roach.
Maybe one that wears a suit. And breathes under water for hours.
It sounds like bad sci-fi. But researchers actually built them. They turned Madagascar hissing cockroaches into amphibious cyborgs. The study just dropped in Nature Communications.
These bugs aren’t natural swimmers. They get a diving rig. It looks like a shell with oxygen tubes attached to their thoracic spiracles—basically the holes they use to breathe air. The tubes act like a regulator. Like scuba gear but tiny.
“We allowed it to survive… transforming it into an amphibious cyber robot.”
The idea is simple. Terrestrial bugs hate water. This setup tricks them. Now they can operate where oxygen is thin or nonexistent. Under water, they live.
Why roaches.
Because they’re tough. They’re big—about 7.5 centimeters, or roughly your finger length. And they last. They live up to five years if you don’t squash them. Most other bugs die way too fast or break too easily.
You probably won’t use one to clean your kitchen sink. The real goal is disaster zones. Flooded ruins. Pipelines that humans can’t enter. Places that are wet, dark, and full of debris.
Hirotaka Sato leads the team at Nanyang Technological University. He says roads get blocked after floods. Access routes vanish. A small robot doesn’t need a road. It needs to crawl. And swim.
Can it replace a human search-and-rescue dog? Maybe not today. But it opens a lane. An amphibious lane.
Locusts could get the same treatment later. Beetles too. The platform isn’t limited to this one species. But for now it’s the hissing kind. Loud enough to be heard over the bubbles.
What else will they swim to? We will find out soon enough
