The animal on the cover of Learning React Native is a ringtail possum (Pseudocheirus peregrinus), a marsupial that is native to Australia. Ringtail possums are herbivorous and live primarily in forested regions. It is named for its prehensile tail, which is often coiled at the tip.

Ringtail possums are gray-brown in color and can grow up to 35 centimeters in length. The diet of the ringtail possum consists of a variety of leaves, flowers, and fruits. They are nocturnal and live in communal nests known as dreys. As marsupials, ringtail possums carry their young in pouches until they are developed enough to survive on their own.

The ringtail possum population declined steeply in the 1950s but has recovered in recent years. However, they are still at risk of habitat loss due to deforestation.
