Previously, scientists only had evidence that roundworms could remain dormant for up to 40 years.
Scientists have managed to revive worms that have been frozen for about 46,000 years. Sky News reported this.
A small group of worms that lived in the late Pleistocene period was found at a depth of 40 meters in the permafrost of Siberia. Members of the species Panagrolaimus kolymaensis are not dead, but in a dormant state known as cryptobiosis, which makes their vital signs invisible.
The worms were revived by giving them food and water. They lived less than a month, but have since produced more than a hundred generations of new caterpillars.
So far, scientists know of very few animals that can stop their vital activities in response to harsh environmental conditions.
It was previously reported that scientists believe bowhead whales can be pregnant for up to two years.
