 Good morning. I'm Layla Faldel. A hippopotamus can fly? Well, sort of. They weigh 8,000 pounds. They're heavier than any animal on Earth besides elephants. And yet scientists in England have found that hippos can stay in the air for three-tenths of a second when they move fast. That's a surprisingly long time for an animal that size. Turns out hippos gain momentum while moving because they're trotting instead of walking. Just hope they don't come trotting at you. It's Morning Edition.
