Benthic spawner. When fertilization takes place their eggs are laid on the sea bed, secured on rocks to ensure they are not swept away by the currents. These fish are born females and during their lifespan they change to males triggered by internal factors, with the exception of some that are born males and stay males, known as ‘primary males’. They have low fecundity rates, meaning they do not lay a large amount of eggs each time they reproduce, but have a reproductive cycle that is not limited to a particular season, being active throughout the year. When eggs hatch the parental care of the larvae is minimal to nonexistent, as the larvae are ‘pelagic larvae’, dispersed in the open sea.
