What's wrong with Nemo's fin?
Also know, why does Nemo have a bad fin?
In the film, he is Marlin's son and is the sole survivor of the barracuda attack, after his mother Coral and his many brothers and sisters died. Damage to his egg left one of Nemo's fins smaller than the other, affecting his ability to swim.
Likewise, did Nemo's mom really die? Nemo's opening scene reveals that Nemo's mom, Coral, was killed by a barracuda. In the film, this just makes Marlin that much more protective of his son. So, after Coral's death, Marlin should have become Nemo's mom instead of his dad.
In this manner, did Nemo get flushed down the toilet?
Oh, no! Nemo plays dead in the hopes that the dentist will flush him down the toilet and back into the ocean. But, little does he know that Nemo's managed to get himself flushed down a drain and has popped up back in the harbor, too.
What is the real meaning of Finding Nemo?
As we know from the Jules Vernes classic sci-fi Twenty Thousand Leagues Under The Sea(s), the name “Nemo” is actually Latin for “no one.” In that story, Captain Nemo goes by that particular title in order to maintain his anonymity and his seclusion from the land-based civilization of man.
