Can you name this interesting animal? Do you know what makes this animal — and others like it — special?


You may have recognized this animal as a kangaroo, but do you know why it's special?

It's a marsupial! Kangaroos, opossums, koalas, sugar gliders, wombats, and Tasmanian devils are all common examples of marsupials.

  • Do you know what these animals have in common?

Marsupials, like other classifications of animals, have certain characteristics in common. One feature all marsupials have in common is a pouch. Some marsupials have pouches that are more visible than others.

  • Can you see the pouch on the kangaroo to the left, and on the wallaby to the right?

Show where the pouches are located on both animals:

Marsupials give birth to their babies early. The babies are underdeveloped, small, and fragile. They stay in the mother's pouch and get nutrients from the mother's milk. Marsupials stay in the mother's pouch for weeks, or sometimes even months!

Read the list below to see how long different marsupials stay in their mother's pouch: 

  • kangaroos: six to eight months
  • wallabies: nine months
  • sugar gliders: sixteen days
  • koalas: six months
  • wombats: six to eight months
  • tasmanian devils: four months

Now, answer these questions:

  • Which marsupial stays in its mother's pouch the longest?
  • Which animal stays in its mother's pouch for the shortest amount of time?

That's right! Wallabies stay in their mother's pouch the longest. Sugar gliders spend the shortest amount of time in their mother's pouch. They are ready to leave their mother's pouch by the time they are sixteen days (that's just a little more than two weeks) old!

The picture below shows a sugar glider:

Marsupials are mammals. This means they all have the same characteristics as mammals.

Mammals are vertebrates. This means they have a backbone. They are all warm-blooded creatures. This allows them to regulate their body temperature and keep it at a consistent rate during their lifetime. All mammals have fur or hair.

  • Can you see the fur on the Tasmanian devil below?

One of the most fascinating things about mammals is that they give birth to live babies and feed their babies milk.

  • Can you think of some other mammals?

Elephango's Philosophy

We help prepare learners for a future that cannot yet be defined. They must be ready for change, willing to learn and able to think critically. Elephango is designed to create lifelong learners who are ready for that rapidly changing future.
