Human babies think they’ve got it made. But the life of a young Southern Greater Glider is even better. Instead of being wheeled to the supermarket in a pram, they get to glide through the air in their mother’s pouch. Even after they’ve matured beyond pouch age, they ride on their mum’s back for a further three months.

While they do have big teddy bear ears, this isn’t a Dumbo situation. Instead, they use the membrane between their forearm and tibia to fly through the forests of Southeastern Australia. Many of these little marsupials grow up to become property tycoons, maintaining up to 20 tree-trunk dens at any given time! Sadly, logging and land-clearing has put their habitat at risk, and the species is now listed as endangered.
