They have survived on earth for tens of millions of years, but our understanding of them is only in the last few decades. For example, it was only in 1991 that the real spawning grounds of the eel were discovered. The sex of the eel is controlled by environmental factors and density, and when the density is high and there is not enough food, the eel will turn into a male, and vice versa, it will turn into a female. In the rivers of Taiwan, eels are mostly females due to their small numbers.
