Clownfish will actively degenerate

Clownfish, scientific name Amphiprioninae. Named because it has one or two white stripes on its face, resembling a harlequin in Peking Opera, it is a tropical fish.

In a population of clownfish, the largest one is the female, the second largest is the male, and the rest are small fish of undifferentiated sex. Therefore, when the female clownfish (the largest one) dies, the original male (the second largest one) will automatically change sex and take over the role of the female clownfish, while the largest of the undifferentiated small fish will become a male fish.

In the vast ocean, there are actually many fish with transgender ability, such as grouper, red silk fish, sheephead fish, parrotfish and so on.
