The pouch of a kangaroo is commonly referred to as a ‘marsupium.’
This unique feature is a characteristic of marsupials, which are a group of mammals that includes kangaroos, koalas, and opossums. The marsupium serves as a protective and nurturing environment for the young kangaroos, or joeys, allowing them to develop and grow after birth. The pouch is not only an essential place for them to stay safe, but it also provides access to their mother’s milk until they are ready to venture out on their own.
