Why can the diapause period of fairy shrimp last for decades?

Because it is very survivable and adaptable, it can adapt to many harsh environments.

During diapause, female fairy shrimp send a biological message telling their eggs to "do not hatch", and on the 13th and 27th day after their eggs are laid, they will stop hatching. At the same time, this biological message also informs their eggs that when the next rainy season comes, it is time to "hatch".

Fairy shrimp are both fertile and adaptable.

This biometric information may be a chemical reaction that stops the biological clock of the female fairy shrimp by telling the eggs. As long as it is kept in a state of drought, the diapause period is at least 20 years.

In a bad environment, the eggs will stop developing and hatch until the environment is suitable.

Prevent breeding offspring in harsh environments.

According to scientists, the reproduction ability and adaptability of fairy shrimp are very strong, and its eggs can be dormant for many years in harsh environments such as drought, cold, and high temperature, until they hatch and regenerate when they encounter water. Even if the environment is bad, the eggs will stop developing until the environment is suitable for hatching.

This is all in order to adapt to the living environment, and it is a last resort.

Because the living environment is not good, it is easy to be born to die.

It is possible to avoid production at the wrong time.

This is the ability of the organism itself, the way the average person understands it.

Fairy shrimp mainly live in some small ponds, pits, paddy fields or ditches and other temporary small waters, so the requirements for water quality should not be high.

The scientific name of the fairy shrimp is "the branch-frontal worm", because of its beautiful appearance, it is called "fairy shrimp", specifically it belongs to the "hairpin-fronted worm family" a kind of aquatic animal, its life cycle is short, rural paddy fields are more common, India and Thailand have the species documented.

The fairy shrimp has black eyes, brown or light yellow, light green, a forked tail, a dozen pairs of legs on the abdomen, a body length of about two centimeters, and a lifespan of only two or three months.

Environment: Fairy shrimp have been around for more than 200 million years and are a collective term for small freshwater crustaceans. They have a strong ability to survive, at the bottom of a dry lake, they can endure several years of high temperature baking and frozen soil, while the eggs of fairy shrimp can survive for tens of millions of years.

And because the egg shell of the fairy shrimp has a "thermal insulation layer", the eggs of the fairy shrimp can not be destroyed in boiling water.

Smaller than a grain of sand, fairy shrimp eggs have a hard protective shell, it is also a real thermal protective layer, can withstand the steaming of boiling water and still have vitality, a tiny egg can wait for 10,000 years until the day when the water arrives and the environment is suitable for hatching, they are called a miracle of the biological world.

The scientific name of fairy shrimp is "branch-frontal worm", because of its beautiful appearance, it is called "fairy shrimp".

If you can, go to a pond or river to get water, but make sure there are no contaminants in it. Fairy shrimp can be fed yeast powder or soy milk every other day, but green water (exposed to the sun and rich in green algae) is the best food, and it is not easy to spoil the water.
