Tardigrades (Water Bear) is one of Ecdysozoa Supefilum, Tardigrada phylum. It size is very small and it lives in water. Water bear also has eight feet. For the first time Tardigrades was described by Ephraim Goeze in 1773.
Tardigrades means “slow-walker”, it was given by Spallanzani (1777). Adult Tardigrades body length is 1,5 mm, the smallest is 0,1 mm and its larva length is 0,05 mm.

Tardigrades can be found in worldwide, from the top of Himalaya until the bottom of ocean and from the poles to the equator. They love to live in a place where there is much algae. You can find them on the beach, land, although in the water.The most interesting thing of this animal is its ability to adapt in extreme environment. Tardigrades can survive in frozen environment (0 degree C) and in a place with high temperature (151 degree C)It can even withstand against radiation 1,000 times higher than the amount of radiation the other living can survive. Therefore, Tardigrades known as an animal that is polyextremeophiles.
With this capability, Tardigrades is a living that can survive if there is a nuclear war or an extreme cataclysm. Even Tardigrades can live for 120 years in dried condition.
Tardigrades sent to space using a spacecraft FOTON-M3 by European Space Agency. From the research, the scientists said that Tardigrade has another ability to survive in space that is no oxygen (vacuum) for 10 days. And also it can survive against cosmic ray and UV radiation of the sun 1000 times higher than the radiation at the earth’s surface.
