Speaking of cockroaches, many people are very disgusted, because it not only crawls everywhere and eats everything, but also carries a lot of pathogens, and is a mechanical transmitter of some pathogens.
Cockroaches are very powerful, even a hundred million years earlier than dinosaurs, so that they survived from hundreds of millions of years, is this hardcore? A biologist once made a conclusion based on the ecological habits of cockroaches: if one day there is a global nuclear war on the earth, all organisms in the affected area, including humans and even fish, will disappear, and only cockroaches will continue their lives! What a terrible life force!
In Toy Story, the uninhabitable earth, Xiao Qiang is still alive
According to studies, in the case of only dry food and no water, females can only survive for 40 days, and males can only survive for 27 days. If there is no water to eat, the female can survive for 90 days and the male can survive for 43 days! Cockroaches are water-intolerant!
Even cockroaches without heads can survive for ten days, and the reason is that they are starved to death, not because they die without blood loss on their heads!
What is even more infuriating is that as long as the female cockroaches mate once, they will lay eggs all their lives, and generally there is a cockroach in the family, and there are at least 20,000 cockroaches in that family!
