This kind of creature can escape from the digestive system of frog and escape from its anus intact!

We all know that there are only two ways of biological digestion: physical digestion and chemical digestion. Physical digestion is a process in which the food particles become smaller and smaller through oral chewing and the rolling of poultry muscle stomach. Chemical digestion is the process of transforming macromolecular food into small molecules through the catalytic reaction of digestive juice and various enzymes.

We can often see from some film and television works that some people swallow a small amount of gold, and the gold will not react too much with the stomach acid in the human body, so it can be pulled out through their own defecation. So, if a small life is eaten in, can it be completely discharged?

Don’t be surprised, Shinji Sugiura, an ecologist at Kobe University in Japan, recently published a research report in current biology, which revealed the escape of aquatic beetles from the digestive system of frogs. Let’s look down together!

Ecologist Dr. Shinji Sugiura wanted to know what would happen to frogs and beetles if they shared a room? So it did an experiment with an aquatic beetle, regimbartia attenuata, and a black spotted lateral fold frog.

From the picture, we can see that the beetle and the frog met as scheduled in this transparent plastic box. Sure enough, the frog swallowed the beetle without hesitation.

Amazingly, 115 minutes later, the aquatic beetle crawled out of the other end of the frog intact. Not only did the beetle escape from the predator’s gut, it was as vibrant as ever.

Before that, some people suspected that frogs would spit out beetles. Now, it seems that this phenomenon is conclusive evidence. Dr. Shinji Sugiura said that in his experiment, 93% of frogs could escape from the anus of frogs within four hours after being fed the beetle, and the beetle often mixed with the dung of frogs. What’s more surprising is that the beetle’s fastest escape speed has reached 6 minutes.

Aquatic beetles are the general name of thousands of aquatic insects. Their body is about 2 cm long and their back is concave and convex. The scientists found that the aquatic beetle in the experiment has been able to evolve into a better swimmer by kicking, and they can breathe in the water by getting a small bag of air under the wing cover. So they can survive in frogs for a while.

Of course, scientists can’t find out how this beetle makes frogs excrete in time. Maybe we need to further study in the future to find out the secret.

But Xiaobian’s brain hole is wide open. What if this beetle is eaten by frogs in infinite circulation and excreted in infinite circulation?
