Is that a mouse?🐭 Guess again: This pocket-sized critter is the western pygmy possum! (Cercartetus concinnus). One of the world’s smallest possums, this species typically weighs just 0.5 oz (13 grams)— the size of an AA battery. This dainty marsupial is a nectivore, meaning that its diet consists primarily of plant nectar. It inhabits treetops in forests throughout parts of southern Australia, using its long prehensile tail like a fifth limb as it moves from branch to branch.
