Snakes belong to biological species. Whether it is soaked in water or other liquids for a long time, it is out of the original state of life. If there is no oxygen, you can't eat when soaking. The liquid soaked for a long time will corrode the snake's skin, and the longer the time, the greater the corrosion. Although snakes have the characteristics of hibernation and can persist for a long time without eating, the environment is completely different from being soaked.

If "it was fished out alive and bit its owner", there is only one possibility:

The snake's "teeth" have not been corroded or softened by the soaked liquid. Compared with the sharp teeth of snakes, human skin is very soft and fragile. After taking out, if the skin touches or touches a sharp surface, it may cause bleeding and the illusion of "being bitten".

I hope I can help you.

Have a nice day.
