That means that Marlin, Nemo's father, will be a lady one day!
Does that mean that Marlin will one day be Nemo's mother?
Of course not.
Marlin will always be Nemo's father.
Because he was a boy when Nemo was conceived, and still a boy when Nemo hatched.
God loves you!
Sincerely,
David S. Annderson
P.S. If a clownfish will actually turn into a girl after being a boy, why do we make a big deal about a boy dressing up as a pretty girl? If clownfish do it, clearly it isn't unnatural, and no one gets hurt, so why the big fuss? After all, David Bowie didn't hurt anyone!
