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.
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 ...
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.
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.

The blue-banded goby (Lythrypnus dalli) is a small fish found in shallow coastal waters of Southern California, commonly inhabiting eelgrass beds and rocky reefs. Known for its vibrant blue stripes, it exhibits both simultaneous and sequential hermaphroditism, with larger females more likely to transition to male roles.
Our society has convinced us that there are just two options for gender identity, "male" and "female," based on biological sex. But in reality, there's more fluidity. Gender identity is on a ...
Lythrypnus is a hermaphroditic fish that is able to change sex. Depending on its size and shape, Lythrypnus Dalli is able to have both male and female reproductive function. Species
The juveniles have an area of black colour which covers most of the head. As the fish grows this breaks up starting with the lips which turn bluish white and their caudal fins begin to darken to become black. This species, like all marine angelfish, is a sequential protogynous hermaphrodite and the younger sexually mature adults are all females ...
