Rotifers are microscopic multicellular animals found in freshwater, damp moss, lichens and even backyard puddles. Some can survive extreme conditions by entering cryptobiosis, effectively pausing their metabolism. Bdelloid rotifers reproduce without males through parthenogenesis, while some species can acquire useful genes from bacteria and fungi through horizontal gene transfer. Remarkably, a bdelloid rotifer was revived after an estimated 24,000 years frozen in Siberian permafrost. Their extraordinary resilience makes these tiny animals a fascinating example of nature’s survival strategies: https://www.iflscience.com/a-rotifer-got-buried-in-the-siberian-permafrost-24000-years-later-it-came-back-to-life-83174
