Garden snails mating. A hermaphrodite (/ h ər ˈ m æ f r ə ˌ d aɪ t /) is a sexually reproducing organism that produces both male and female gametes. [1] Animal species in which individuals are either male or female are gonochoric, which is the opposite of hermaphroditic.
Sexual dimorphism also occurs in hermaphroditic fish. These species are known as sequential hermaphrodites. 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.

A sequential hermaphrodite produces eggs (female gametes) and sperm (male gametes) at different stages in life. [2] Sequential hermaphroditism occurs in many fish, gastropods, and plants. Species that can undergo these changes do so as a normal event within their reproductive cycle, usually cued by either social structure or the achievement of ...
Most fish are gonochorists, but hermaphroditism is known to occur in 14 families of teleost fishes. [13] Usually hermaphrodites are sequential, meaning they can switch sex, usually from female to male . This can happen if a dominant male is removed from a group of females.
Hermaphrodite species include the common earthworm and certain species of snails. A few species of fish, reptiles, and insects reproduce by parthenogenesis and are female altogether. There are some reptiles, such as the boa constrictor and Komodo dragon that can reproduce both sexually and asexually, depending on whether a mate is available.
