In 2023, it was reported that nematodes of the previously undescribed Panagrolaimus kolymaensis were revived after 46,000 years in cryptobiosis. [2] [3] However, a number of scientists expressed skepticism regarding the accuracy of the age analysis for these worms. [1] Phylogenetic analysis and genome comparison with C. elegans revealed that ...
Scientists have revived a worm that was frozen 46,000 years ago — at a time when woolly mammoths, sabre-toothed tigers and giant elks still roamed the Earth.

[13] [14] In 2023, it was reported that nematodes of the previously undescribed Panagrolaimus kolymaensis were revived after 46,000 years in cryptobiosis. [15] Like bacterial spores, plant seeds are often capable of germinating after very long periods of metabolic inactivity.
Once thawed and hydrated, the worms bounced back to life, eating bacteria and producing offspring, researchers said. 46,000-year-old worms discovered on Arctic expedition. Now they’re being revived

Nematodes are very small, slender worms. Most are free-living, often less than 2.5 mm long and some only about 1 mm. Many nematodes are microscopic. Some soil nematodes can reach up to 7 mm in length, and some marine species can reach up to 5 cm. Some are parasitic and can reach lengths of 50 cm or more. [42]
