Eutardigrada More than 1000 species of tardigrades have been described. Tardigrades occur over the entire world, from the high Himalayas (above 6,000&_160;m), to the deep sea (below 4,000&_160;m) and from the polar regions to the equator. The most convenient place to find tardigrades is on lichens and mosses. Other environments are dunes, beaches, soil and marine or freshwater sediments, where they may occur quite frequently (up to 25,000 animals per litre). Tardigrades often can be found by soaking a piece of moss in spring water.[3] Water bears are able to survive in extreme environments that would kill almost any other animal. They can survive temperatures close to absolute zero[4], temperatures as high as 151°C (303°F), 1,000 times more radiation than any other animal[5], nearly a decade without water, and can also survive in a vacuum like that found in space.
