Will kids never learn? This weekend brings the rerelease (in 3-D) of Pixar’s “Finding Nemo,” in which Nemo doesn’t listen to his dad AGAIN and gets lost AGAIN. But that little clownfish isn’t alone when it comes to movie characters who just keep swimming.

Jaws (1975)
While directing the granddaddy of all summer blockbusters, Stephen Spielberg named his very toothy star Bruce, after his lawyer. We assume his lawyer didn’t have the same taste for New England flesh.

The Little Mermaid (1989)
The title character may have been a bikini-clad human-fish hybrid, but her seafaring co-stars included Flounder, who looked nothing like a flounder, and Sebastian, who did look like a tasty, tasty crab. Bring on the Old Bay!

Big Fish (2003)
In what’s possibly Tim Burton’s most underrated film, Albert Finney plays a man who claims to be part catfish. With all the tears you’ll shed, the fish won’t be the only one who’s soaked.

Free Willy (1993)
If you love something, you should set it free. If it comes back, it’s yours. If it swims off into the wild and eats a ton of seals, it’s a killer whale and you should let it go.

Moby Dick (1956)
Man, do not tick off Gregory Peck, because he will hunt you down and kill you, no matter how big you are. Also, do not watch this movie when you’re assigned the book in school. They skip stuff.
