Musky-rat kangaroo

This marsupial is the smallest kangaroo in the world weighing only half a kilogram with dark brown fur and no bigger than a large guinea pig. It is more similar to a possum than other kangaroos. It bounds along on all fours.

It is also the oldest, or most primitive kangaroo having evolved 20 million years ago.

It regularly gives birth to twins unlike other kangaroos and is active during the day foraging on the forest floor for fruits and seeds as well as fungi & vertebrates. At night it sleeps in a nest of leaves and generally keeps to itself. Sometimes groups are seen under fruiting trees.

They inhabit almost the entire wet tropics, both lowland and upland forest and are found nowhere else.
The scientific name is Hypsiprymnodon moschatus and is sometimes referred to as 'hypsi'.
