TARDIGRADE Tardigrades phylum of E]ecdisozoos within the animal kingdom, characterized by being invertebrates, protostomes, segmented and microscopic, of the order of half mm. long caterpillar-like shaped, walking slowly, similar to how a bear does. They are the most resistant beings on the planet, as they survive freezing at almost absolute zero and boiling water at 150°C. Years can go by without drinking water. Their body survives if they are fired by a cannon at high speed, although it is studied because they become sterile after this event. They can withstand 6000 atmospheres of pressure and the cold and radiation of space. They are more widespread than humans and there will be virtually some of them in any small portion of water that is analyzed. Tardigrades are investigated as possible contributors to the advancement of technology for their resistance in extreme conditions and their different states of E]cryptobiosis
