Historically, the term hermaphrodite has also been used to describe ambiguous genitalia and gonadal mosaicism in individuals of gonochoristic species, especially human beings. The term comes from the name of the minor Greek god Hermaphroditus, son of Hermes and Aphrodite (see below).

Historically, the term hermaphrodite has also been used to describe ambiguous genitalia and gonadal mosaicism in individuals of gonochoristic species, especially human beings. The term comes from the name of the minor Greek god Hermaphroditus, son of Hermes and Aphrodite (see below).
Recently, intersex has been used and preferred by many such individuals, encouraging medical professionals to use the term.
Sequential hermaphrodites
Sequential hermaphrodites (dichogamy) occurs in species in which the individual is born as one sex but can later change into the alternate sex. This is in contrast with simultaneous hermaphrodites, in which an individual may possess fully functional male and female gonads. Sequential hermaphroditism is common in teleost fish, especially marine reef species. While some sequential hermaphrodites can change sex multiple times, most can only change sex once.
Sequential hermaphrodites fall into two broad categories:
- Protandry: Where the organism is born as a male, and then changes sex to a female.
- Example: The Clownfish (Genus Amphiprion) are colorful reef fish found living in symbiosis with anemones. Generally one anemone contains a 'harem', consisting of a large female, a smaller reproductive male, and even smaller non-reproductive males. If the female is removed, the reproductive male will change sex and the largest of the non-reproductive males will mature and become reproductive. It has been shown that fishing pressure can change when the switch from male to female occurs, since fishermen naturally prefer to catch the larger fish. The populations are generally changing sex at a smaller size, due to artificial selection.
- Protogyny: Where the organism starts as a female, and then changes sex to a male.
- Example: Wrasses (Family Labridae) are a group of reef fish in which protogyny is common. Wrasses also have an uncommon life history strategy, which is termed diandry (literally, two males). In these species, two male morphs exists: an initial phase male or a terminal phase male. Initial phase males do not look like males and spawn in groups with other females. They are not territorial. They are perhaps, female mimics (which is why they are found swimming in group with other females). Terminal phase males are territorial, and have a distinctively bright coloration. Individuals are born as males or females but if they are born males, they are not born as Terminal Phase males. Females and initial phase males can become terminal phase males. Usually the most dominant female or initial phase male replaces any terminal phase male, when those males die or abandon the group.
