Tardigrades can stop their metabolism – meaning they pause all biological activity. This eliminates their upkeep in terms of energy, water, food, etc. Once favourable conditions return they will resume metabolism and get back to normal.

They also have special proteins in their cytosol that changes the cell into a crystal-like structure when there is no water. Crystals are incredibly stable and will protect the cells from environment damage for a long time.

Tardigrades also happen to have an incredible resistance to radiation due to a protein called “Damage Suppressor” (yes that is it’s real name). The exact mechanism of how it works is unknown but the protein was shown to be able to grant radiation resistance to human cells.

They are connected to the Mycelial network that crosses into different dimensions. Since they exist in a multidimensional state, they are very resilient as they must be damaged in all the dimensions they exist in to harm them.
