“Alien creatures” are very patient and defecate again after two years, which arouses scientists’ thinking

With the continuous progress of human civilization, all kinds of ideas have changed. For us humans, defecation is a process of privacy, which can not be seen by others. This is also the embodiment of the progress of civilization. But animals in nature don’t have these concerns. They don’t have this kind of consciousness. The giant legged insects living in an aquarium in Japan are surrounded by a large number of spectators when they defecate. What’s the matter?


Guangming.com reported in June that an incredible scene was recently staged at an aquarium in Niaoyu City, Sanyo Prefecture, Japan. Several large and small legged insects reared in the aquarium defecated again after more than two years, attracting many tourists. It is estimated that many friends will be curious when they see this. Is animal defecation so beautiful? If you have never seen this animal before, but have heard of it, you will be curious.

What kind of creature is the giant legged insect, known as “alien creature”?


In addition to octopus and squid in the deep sea, giant legged insects are also known as “alien creatures”. It won the title because it looks like an alien in a science fiction movie. In particular, the giant’s face is more similar to that of aliens, with a large head and narrow eyes. It also has very hard “armor” on its back. Under the armor are many pairs of feet, which look very similar to the big bugs flying in the air in the Avengers.


An adult giant beetle is about 40 cm long, about the size of a pet cat. This also makes them the largest polypod in the world. In addition to the appearance, the defecation frequency is another highlight, which attracts the most attention of the audience and researchers. According to the staff of the aquarium, their last defecation time was in 2018, which shows how strong their patience is.

The peculiarity of the great king’s legged insect has aroused people’s thinking


Scientists have been inspired by the discovery that there should be a link between the speed of metabolism and the length of life. The fact that the giant beetles can defecate only once every two years means that their metabolism is very slow. At the same time, their average life span is between 40 and 60 years. Therefore, some studies suggest that the slower the metabolic rate of organisms, the longer their life span.


In fact, many biologists have been concerned about metabolic rate and longevity long before, and also proposed that there is a negative correlation between them. For example, the metabolic rate of house cat and King’s armyworm is completely different. Domestic cats represent the metabolic rate of thermostatic animals, while giant catfish represent the very slow metabolic rate. However, the average life span of domestic cats is only more than ten years, while the life span of C. giganteum can reach 40 years or more, which shows the sharp contrast between life span and metabolism.

Can we prolong our life if we slow down our metabolism?


Inspired by other creatures, human beings will eventually focus on their own development. Human is a kind of thermostatic animal, and its metabolism speed is several times or even dozens of times faster than that of most warm animals, but this does not mean that human life is shorter than that of animals.


The author thinks that even if some experiments prove that reducing the metabolic rate can prolong people’s life, we can’t significantly reduce the metabolic rate in exchange for a longer life, because we are always thermostatic animals, and all parts of the body need energy, and the main way to produce energy is metabolism.
