Clownfish are transsexuals.

Clownfish live in a hierarchical society led by a dominant female. If this female were to die, she would be replaced by her mate. The male changes his sex and every other fish follows suit, moving up a rung on the social ladder. Clownfish also maintain a body mass 20% smaller than the fish that outranks it.

To summarize – in Finding Nemo, Nemo’s dad should have become a woman and mated with his son after locating him!
