Live Science notes that they are popular enough to appear on merchandise like clothes, earrings, and keychains, with crochet patterns for people to make their own tardigrade. [75] The Dutch artist Arno Coenen [ nl ] created statues for St Eusebius' Church, Arnhem of microscopic organisms including a tardigrade and a coronavirus .
Tardigrades are small arthropods able to tolerate extreme environments. Many live in tufts of moss, such as on rooftops, where they get repeatedly dried out and rewetted. Others live in the Arctic or atop mountains, where they are exposed to cold. When dried, they go into a cryptobiotic 'tun' state in which metabolism is suspended.
Tardigrades have been shown to respond to different temperature changes at different developmental stages. Specifically, the younger the egg, the less likely it is to survive extreme environments. However, not too long after development, tardigrades demonstrate a remarkable ability to withstand these conditions.
Tardigrades are affectionately known as water bears or moss piglets and are tiny invertebrates measuring a maximum of 0.05 inches in length. Viewed through a microscope, they look a little like a ...
When dried, terrestrial tardigrades draw in their legs and go into a cryptobiotic 'tun' state. They can quickly revive when re-wetted. [1] mg = midgut; go = gonad; pb = pharyngeal bulb; mo = mouth; st = stylet. From the early 19th century, tardigrades' environmental tolerance has been a noted feature of the group. The animals are able to ...
Tardigrades can stay in cryptobiosis for hours or days or even years depending on the conditions around them and are able to revive themselves within up to 24 hours after conditions have improved. However, tardigrades are not considered extremophiles as they do not live in these extreme conditions. [13]
Tardigrades live over the entire world, including the high Himalayas. [4] Tardigrades are also able to survive temperatures of close to absolute zero (−273 °C or −459 °F), [5] temperatures as high as 151 °C (304 °F), radiation that would kill other animals, [6] and almost a decade without water.

Eutardigrada are a class of tardigrades (Tardigrada) without lateral appendages. Primarily freshwater bound, some species have secondarily gained the ability to live in marine environments . By cryptobiosis many species are able to live temporarily in very dry environments. More than 700 species have been described.
