EXTRA CREDIT – things that are real and things that are not

Say you're a clownfish living in the Great Barrier Reef off northeastern Australia. Say you've been captured and have ended up in a dentist's aquarium. Could you count on your dad to rescue you? You can earn extra points if you can figure out which parts of the movie are fact, and which parts just don't float.

MMM...SCRAMBLED EGGS: Like a real clownfish, Nemo's dad, Marlin, tries to defend his nest when a vicious barracuda plows in for a feeding frenzy. Do barracuda really have a taste for eggs?

LOOK MA—NO CAVITIES: Yikes! Marlin is trapped in a whale's stinky, slimy mouth! But somehow he survives without getting chomped. How?

THANKS A LOT, DAD: Should Marlin be a candidate for Worst or Best Father of the Year for telling Nemo to swim through stinging anemones? Why?

UNDERWATER EXPRESSWAY: When Marlin and his travel mate, Dory, need to make it in record time from the deep ocean to Sydney, Australia, they hop on the East Australian Current. Does this highway really exist?

SAY THAT AGAIN: Dory the regal blue tang couldn't remember the color of her scales if she wanted to. Are fish just that dumb, or are they capable of learning?

CHEW ON THIS: Marlin and Dory meet a great white shark named Bruce who claims to be a vegetarian. You'd have to have fish for brains to believe that, but are there any sharks that could be?
