Tardigrade

Tardigrades are a globally distributed group of small invertebrates measuring up to 1 mm in length. They feed by using their sharp stylets to pierce and consume the cells of plants and animals. However, they are especially known for their remarkable ability to survive in extreme conditions. Tardigrades can be found in diverse habitats, from ice-covered regions and hot springs to soil and deserts, though most species prefer moist environments. When conditions unfavorable, tardigrades can enter a state of anabiosis, in which they almost completely desiccate. In this state, they can withstand extraordinary conditions, such as temperatures near absolute zero (-272 °C), or, conversely, temperatures up to 150 °C for short periods. They are also the only organisms known to survive in space for several days. Remarkably, at a "milder" temperature of -20 °C, tardigrades can survive for at least 30 years.
