Hermaphroditic fishes are almost exclusively sequential—simultaneous hermaphroditism is only known to occur in a few fishes, such as the Rivulid killifish Kryptolebias marmoratus [10] and hamlets. Teleost fishes are the only vertebrate lineage where sequential hermaphroditism occurs.
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 evolution of anisogamy possibly contributed to the evolution of Simultaneous hermaphroditism. [6] It is known that simultaneous hermaphroditism that exclusively reproduces through self-fertilization has evolved many times in plants and animals, but it might not last long evolutionarily.
