What kind of music do kangaroos listen to? Hip-hop, of course! Of course, kangaroos don’t really listen to music like we humans do. If they did own MP3 players and listen to music, though, we suppose they could like country, rock or even classical music.

We think kangaroos would be the perfect animals to take up the hobby of listening to music. Why? They could put their MP3 players and headphones into their pockets when they’re not using them!

Kangaroos are mammals that are part of a special group known as “marsupials.” Marsupials are mammals that have a special pouch used for carrying their babies. In addition to kangaroos, other marsupials include the wombat, the koala, the opossum and the wallaby.

Kangaroos and other marsupials have a special pouch — called a “marsupium” — for carrying their babies because their young are particularly small when they’re born. A baby kangaroo — called a “joey” — is about the size of a lima bean when it’s born!

The mother’s pouch provides a safe place for her babies to stay until they grow large enough to survive outside the pouch on their own. Since pouches are for babies to stay in, only female kangaroos have them.

Male kangaroos who want pockets simply have to wear pants. Just kidding! Kangaroos don’t wear pants, of course.

Can you imagine what kangaroo pants would look like? They would have to be very flexible to accommodate those long legs and all that jumping! Plus, where would the tail stick out?

Because of their long feet, kangaroos can’t walk normally. Instead, they use their big, powerful hind legs to hop wherever they want to go. They also use their muscular tails to help keep their balance.

The animals we call kangaroos are usually one of four species native to Australia: the red kangaroo, the eastern grey kangaroo, the western grey kangaroo and the antilopine kangaroo.

Fully grown kangaroos are usually 5 to 6 feet tall and weigh 50 to 120 pounds, although large kangaroos can weigh as much as 200 pounds.

Kangaroos usually live and travel in organized groups of 10 or more. These groups are called “mobs,” “troops” or “courts.” Male kangaroos are often called “boomers,” “bucks” or “jacks,” while female kangaroos are often called “does,” “flyers” or “jills.”

So, if you’re ever in Australia and you see a group of kangaroos that includes a father, mother and a baby, you can say you saw a jack, a jill and a joey in a mob. And locals will probably know exactly what you’re talking about!

  2. Hi, this is Wyatt from Mrs. Caplin’s class. I was looking for a cool wonder and I found one. At my zoo, we have a kangaroo exhibit where you can walk through and see them. I had some extra time this morning, so I figured I would leave a comment. The video was adorable. I love kangaroos, so I invited my mom to see the video (she kept interrupting). So thanks thanks for the knowledge on kangaroos.

    • Hi Mrs.masonbaley! We love kangaroos here at WONDERopolis! Maybe you could find more information at your library. Remember when doing presentations, it is always important to cite your sources. The official Wonderopolis Permissions Policy states:

      Wonderopolis materials may be cited or excerpted in periodicals, books, and educational materials under the following stipulations:

        1. A URL of the material referenced is provided so that readers may access it online
        2. Inclusion of the following branding information: “Wonderopolis is brought to life by the National Center for Families Learning.”

      Since our Wonders are sometimes updated, the proper way to cite the publishing date is to list the date you consulted our page for your research. Good luck on your presentation! :)

Have you ever wondered…

  • What do kangaroos keep in their pockets?
  • Are kangaroos the only marsupials?
  • How big are kangaroos when they’re born?

Try It Out

What do you keep in your pockets? It won’t be a joey (we hope), but some people feel lost without pockets.

Many people just like to keep their hands in their pockets. But plenty of folks use them to hold a big variety of things. (Some people have so much to carry that they stuff items in a purse, tote bag or backpack because these hold far more than what fits in a pocket.)

Make a graph and list some of the typical things kept in pockets (besides lint!) at the top of the columns. This might include things like tissues, keys, change and lists. Some people keep a smooth stone that is soothing to rub or a special item to bring luck.

Next, survey family and friends to see the variety of things kept in their pockets. What item is carried the most? The least? What is the most unusual item carried?

When you’re finished, email us what you learned, or post it on Facebook. We can’t wait to read what all you Wonderopolis boomers and flyers keep in your pouches!
