They determined that dioecy was less likely to occur when the size advantage is stronger than other advantages Warner suggests that selection for protandry may occur in populations where female fecundity is augmented with age and individuals mate randomly.Selection for protogyny may occur where there are traits in the population that depress male fecundity at early ages (territoriality, mate selection or inexperience) and when female fecundity is decreased with age, the latter seems to be rare in the field.Protandrous hermaphrodites refer to organisms that are born male and at some point in their lifespan change sex to female. Dominance is based on size, the female being the largest and the male being the second largest.The rest of the group is made up of progressively smaller non-breeders, which have no functioning gonads.Sequential hermaphroditism (called dichogamy in botany) is a type of hermaphroditism that occurs in many fish, gastropods, and plants.Sequential hermaphroditism occurs when the individual changes sex at some point in its life.Wrasses are found around the world in all marine habitats and tend to bury themselves in sand at night or when they feel threatened.

The general structure of the gonads remains ovarian after the transformation and the sperm is transported through a series of ducts on the periphery of the gonad and oviduct. For example, the California sheephead stays a female for four years before changing sex.Initial Phase males have larger testes than larger, terminal phase males, which enables the initial phase males to produce a large amount of sperm.This strategy is able to compete with that of the larger male, who is able to guard his own harem.It can change from a male to female (protandry), or from female to male (protogyny) or from female to hermaphrodite (protogynous hermaphroditism), or from male to hermaphrodite (protandrous hermaphroditism).Those that change gonadal sex can have both female and male germ cells in the gonads or can change from one complete gonadal type to the other during their last life stage. In the Amphiprion percula species, there are zero to four individuals excluded from breeding and a breeding pair living in a sea anemone.

Botryllus schlosseri, a colonial tunicate, is a protogynous hermaphrodite.
