Stoplight Parrotfish
Sparisoma viride
Parrotfish can change sex. It is believed that sex changes
occur when population densities are low, resulting in a lack
of breeding males or females.
Primary males are born male, and remain so throughout their
lives while secondary males are born female, changing both sex
and color to become male. These secondary males are also
referred to as super males (pictured)
