This Is What The Inside Of A Kangaroo Pouch Looks Like

If you've ever wondered what it looks like inside a kangaroo pouch (or even where exactly the pouch is located), here's your chance.

A new episode of the YouTube series "Smarter Every Day" (above) gives a privileged peek inside the hard-to-find pouch -- and if you don't have time to watch the whole thing, just fast-forward to 6:20.

"There's white and black spots in the back," Destin Sandlin, the series' host and creator, says in the video. "It's really small and it stretches out... I always had the misconception that it was like a pocket, right here on the belly, because that's the way it is on cartoons."

Only female kangaroos sport pouches, which contain mammary glands and hold their joeys until they are ready to leave the pouch after an average of 46 weeks or so. A mother roo often cleans her pouch with her tongue, licking away dirt and baby roo poo. Talk about marsupial maintenance!
