Simultaneous hermaphroditism definition
WebbWhen it comes to hermaphrodite fishes, several terms define the range of hermaphroditism. In synchronous and simultaneous hermaphroditism, fish have an ovary and a testis, or an ovotestis. This type of hermaphroditism is most common in fish who inhabit the dark depths of the ocean in low-population densities. WebbIn some species, female and hermaphrodite individuals may coexist, a sexual system termed gynodioecy. [24] In a few species, female individuals coexist with males and simultaneous hermaphrodites; this sexual system is called trioecy. [25] In Thor manningi (a species of shrimp), females coexist with males and protandrous hermaphrodites. [26]

Webb26 sep. 2024 · Hermaphroditism is a reproductive strategy that is advantageous to some fish species. Fish who do not school, who live in deep or murky waters, or who have low population densities can have a hard time finding mates.

Webb1 nov. 2004 · In some simultaneous hermaphrodites, individual gender role is clearly separated between mating partners, with one acting as the sperm donor (the male role) and the other acting as the sperm recipient (the female role).
