Fairy shrimp has existed for more than 200 million years, which is a general term for small freshwater crustaceans. They have strong viability. At the bottom of the dry lake, they can stand the test of high temperature baking and frozen soil for several years. Once the eggs of the fairy shrimp encounter abundant rainfall, they can hatch and gain new life.

Moreover, the eggs of the fairy shrimp will not be destroyed in boiling water, because the eggshell has a "heat insulation layer". Shrimp eggs smaller than sand have a hard protective shell, which is also a real thermal protective layer.

It can resist boiling water and still has vitality. A tiny egg can wait for 10,000 years until the water comes and the environment is suitable. They are wonders of biology. This kind of animal is common in rural rice fields.
