The creatures tend to shut down their systems when they are in unfavourable conditions. This means they won’t move or reproduce, and their metabolism stops.
Carbon analysis has revealed that the worms – also known as nematodes – came from a prehistoric era.
The developments could change the way experts approach bringing back other extinct species, too.
During an analysis, the research team discovered the worms were Panagrolaimus kolymaensis - a species that was previously thought to be extinct.
The scientists wrote in their paper: “Previously, we had shown that nematodes from the Siberian permafrost with morphologies consistent with the genera Panagrolaimus and Plectus could be reanimated thousands of years after they had been frozen.
“Several viable nematode individuals were found in two of the more than 300 studied samples of permafrost deposits spanning different ages and genesis.”
It’s not the only thing that scientists have recovered from permafrost, either.
It was announced earlier this year that scientists are busy working on reviving 'zombie viruses’ that have been lying dormant for tens of thousands of years in Arctic conditions, and while it sounds absolutely terrifying, it could be important when it comes to protecting us all in the future.
