>>53858900>It happens in nature but only with certain species of fish and under specific conditions. Not just fish, and potentially as part of their life cycle.
Clownfish live in groups with a breeding pair which the largest fish is the female and her partner is the largest male, and the rest are non-breeding males. If the female dies the breeding male becomes female and the next largest male becomes the new breeding male.
Hawkfish live as single males with a harem of females, and when a harem gets too big one of the females becomes male and the harem splits. Even more, if the new male loses too many in his harem or get challenged and loses to a competing male he’ll revert back into a female fish.
Humphead Wrasse, when they are big and old enough, change from female to male just as part of their natural life cycle.
Some species of turtles (including the Green Sea Turtle) and crocodilians change sex depending on the temperature that their egg incubates at. You can have eggs that are genetically male hatch as females, then go on and lay and reproduce eggs themselves.
You also have species that are complete hermaphrodites. Many slugs and snails are hermaphrodites, having both male and female genitalia.
Nature gets very strange with sex and gender, and to say “it doesn’t work in nature!” shows profound ignorance.
