It’s the sweetest animal on the face of the earth and very photogenic for a selfie on Instagram.

It is a small marsupial mostly nocturnal (usually sleeps during the day), which interacts with humans and has become the best-known symbol of the island’s wildlife.

❗ It’s forbidden to feed the Quokkas. If you do this, you can be fined and put the lives of these small animals at risk
