Parrotfish has an ability to spontaneously change its gender from female to male.
Parrotfishes are a group of fishes that traditionally has been considered a family (Scaridae), but now often are considered a subfamily (Scarinae) of the wrasses.They are basically found in relatively shallow tropical and subtropical oceans throughout the world, but with the largest species richness in the Indo-Pacific. These approximately of 90 species are found in coral reefs, rocky coasts and seagrass beds and play a significant role in bioerosion.
Change In Gender : The development of parrotfish is complex and accompanied by a series of changes in color termed polychromatism. Almost all species are sequential hermaphrodites, starting as females (known as the initial phase) and then changing to males (the terminal phase).A few species, for example the Mediterranean parrotfish are secondary gonochorist, meaning that some females do not change s*x and the ones that do, change from female to male while still immature (i.e., reproductively functioning females do not change to males).
