How does a newborn kangaroo reach its mother’s pouch?

A newborn kangaroo, known as a joey, is born in a highly immature state, measuring only about 2 cm (1 inch) in length and weighing less than a gram.1

Immediately after birth, the joey relies on its already well-developed, clawed forelimbs to crawl up the mother’s body. It makes its own way to the marsupium, or pouch, which provides the necessary shelter, warmth, and nourishment. Once inside, the joey attaches its mouth to a teat, which then enlarges to hold the young animal firmly in place while it continues its development.12
