15. Not that Nemo
Nowadays, basically, every child recognizes the name “Nemo.” However, long before the little clown fish with an under developed fin was forcefully separated from his father, there was another Nemo winning the hearts of children all over the world. I’m referring to The Undersea Adventures of Captain Nemo which followed Captain Mark Nemo and his trusty assistants Robbie and Christine. They utilized a nuclear-powered submarine named Nautilus to teach children about life under the sea.
