I think that maybe, Finding Nemo is not based on a true story. Today I learned that if the mother clownfish dies, the father clownfish does not become overly protective of the baby clownfish, not allowing it to so to school. In fact, the truth is so much not like that at all.
I learned that clownfish live in groups with one female, one male, and a couple non-reproducing others - presumably cousins who can't find a job. If the mother clownfish dies, the male clownfish becomes a female clownfish and one of the non-reproducing fish become the male clownfish.
Seriously! I can barely comprehend the situation. I'm a bit concerned now nothing in Nemo was true.
Great movie though...
