Tardigrade anatomy [3]. Tardigrades have a short plump body with four pairs of hollow unjointed legs. Most range from 0.1 to 0.5 mm (0.004 to 0.02 in) in length, although the largest species may reach 1.3 mm (0.051 in).
Tardigrades are known to exist in almost every biome on the earth. There are terrestrial species, marine species, and even fresh water species have been found. [4] The eight currently recognized species in the genus Bertolanius Özdikmen have a wide distribution ranging from colder arctic areas, including Norway and Sweden, to more temperate regions like the Mediterranean.

Tardigrades have survived exposure to space. In 2007, dehydrated tardigrades were taken on the FOTON-M3 mission and exposed to vacuum, or to both vacuum and solar ultraviolet, for 10 days. [20] Back on Earth, more than 68% of the subjects protected from ultraviolet were reanimated by rehydration, and many produced viable embryos. [20]
