Tardigrades (Waterbear) also known as waterbears, were first discovered in 1773. Known as the world’s most resilient living creature and a part of the tardigrade (Latin Tardis meaning slow; gradi meaning step) class, water bears are invertebrates with 4 pairs of short legs. Their body length may vary between 0.08 mm and 1.5 mm. Their bodies usually have a cylindrical shape with a flat abdominal area. The cone shaped end is considered the head. They do not have respiratory organs. They are gonochoristic. Their body cells are stable.
They Tardigrades have approximately 960 known species. They are resistant to extreme environmental conditions. Initially thought to live only in fresh water, upon genetic analyses it was revealed that they also migrated to land thanks to their great adaptive abilities. These micro-organisms, which can live in extreme temperatures from 180ºC to -236ºC, are also immune to high radiation and high pressure environments. From deep oceans to the highest mountains, they can live anywhere in the world. It is also discovered that they are able to live in space.
