You’ve heard of koala bears and pandas, but have you heard of a tree kangaroo?

These fluffy tree-dwellers live in the rainforests of northeast Australia and New Guinea, feeding and sleeping at over 100ft above the ground.

Sadly, they’re critically endangered thanks to deforestation and poaching – particularly from the New Guinea locals who hunt them for their meat.

It’s difficult to estimate how many of the 14 species of adorable marsupials are left, but there are just 50 of the Wondiwoi tree kangaroo remaining.

And we still know hardly anything about them.

How sad!
