As in other parrotfish species, males are territorial. They are born female in a female-dominated civilization and can only change their gender as they mature, usually as they get older. This shift is a result of social and environmental factors. When there isn't a male in the group, activation takes place.
Here, sex change is age-dependent. For example, the California sheephead stays a female for four to six years before changing sex [35] since all California sheephead are born female. [38] A terminal-phase male bluehead wrasse. Bluehead wrasses begin life as males or females, but females can change sex and function as males. Young females and ...
Bidirectional sex changers: Where an organism has female and male reproductive organs, but may act either as a female or as a male during different stages in life. [15] Example: Lythrypnus dalli (Family Lythrypnus) are a group of coral reef fish in which bidirectional sex change occurs. Once a social hierarchy is established a fish changes sex ...

In fish, reproductive histories often include the sex-change from female to male where there is a strong connection between growth, the sex of an individual, and the mating system within which it operates. [55] In protogynous mating systems where males dominate mating with many females, size plays a significant role in male reproductive success ...
[17] [20] Population densities and sex ratios of hermaphroditic fishes are also intimately linked to ecological factors and human activities. [20] Spatial and temporal changes in fishing pressure, coupled with environmental changes across populations over time, tend to affect the reproductive potential of each population of California sheephead ...
Like many wrasses, the hogfish is a sequential hermaphrodite, meaning it changes sex during different life stages; it is a protogynous, "first female" hermaphrodite; juvenile hogfish start out as female and then mature to become male. The change usually occurs around three years of age and about 36 centimetres (14 in) in length. [6]
Goldfish has just announced that it's embracing its more mature, sophisticated side with a fitting new name. As of today, Goldfish will now be known as Chilean Sea Bass crackers.
