Behold the western pygmy possum! This dainty marsupial typically weighs ~0.5 oz (14 g)—that's about as much as a AA battery! It inhabits treetops in forests throughout parts of Australia. As a nectarivore, it mainly feeds on plant nectar. American Museum of Natural History @AMNH #Australia #marsupials #animals
