Author's Note: 10 Crazy Facts You Didn't Know About Animals

I seldom pitch article ideas, but I made an exception here. The idea came from watching one of my daughter's favorite TV shows, a nature-education program called "Zaboomafoo" hosted by the Kratt Brothers, from which both of us have gathered some amazing knowledge. Early on, I learned that kangaroos use their tails as kind of a third leg when hopping slowly, which for some reason fascinated me, and each time I've shared the knowledge with friends I've gotten the same response: I didn't know that! So I decided to go deeper and learn some other facts. I left out my daughter's enthusiastic recommendations because I thought my readers might already know them, but in case you're interested: Gazelles run really fast; cheetahs eat gazelles; and lions eat zebras. (I'm guessing we'd watched a predator episode that day.)
