Forget everything you know about kangaroos because the incredibly rare Goodfellows Tree Kangaroo looks more like a bear, lives in the canopy, and is native to Papua New Guinea.
And did we mention they're cute?
This little joey was born at Perth Zoo and is one of only 15 males in captivity worldwide. Australian Fauna Keeper Kerry Pickles said that made him very special.
"His genetics will be very valuable when he reaches breeding age," Pickles said.
Tree kangaroos live in mum's pouches for up to eight months before using their legs, and Pickles said they knew he was in there from an early age.
"The joey was first confirmed in Kaluli's pouch, when it was estimated to be only four days of age," Pickles said.
"We used a small camera to ensure the least intervention to the tree kangaroo mother."
His name is Mian and he's already being introduced to lady tree kangaroos. In the wild, the species is listed as 'endangered' by the International Union for Conservation of Nature with threats from habitat loss and hunting.
