SPECIES: Milnesium alabamae Tardigrada by Sophie Cassou The tardigrada are basically indestructable. They live in the most extreme environments in the world. During severe conditions that could kill mostly anything on earth, the Tardigrades would roll up into balls called “tuns” and they could survive like that for long periods of time. Some can live freezing temperatures such as -273 degrees, and some can live in burning environments (304 degrees), Some can go 10 years without water, and some withstand over 1,000 times more gamma radiation than other animals.
They can take 570,000 rads of x-ray radiation whereas a human would die with a mere 500 rads. •Some can live in a vacuum for a while as well•The tardigrades can survive pressures of up to 6,000 atmosphere•The tardigrades withstood 10 days in space, when they arrived back on Earth they laid eggs and they hatched perfectly http://www.bioone.org/doi/abs/10.1660/062.115.0104?journalCode=tkas
http://www.earthlife.net/inverts/tardigrada.html The word Tardigrada comes from Latin. Tardus means slow and gradu means a step. This translates to slow walker, which describes how they move.
The Tardigrada are also called a water bear. This is because they dwell in water-based environments and they have sharp claws, stubby legs, and awkward, slow movements. The species is distinguishable from other tardigrada because of its wide buccal tube and carni`vorous diet. This specific species stomach can contain mastexes. rotifers, and buccal structures of other tardigrada. This would not be considered uncommon, however, recently this species has eaten an amoeba which is uncommon and the first time it has happened. Milnesium eurysionm is found mainly in Greenland.
