Honey possum

A marsupial that weighs 5 to 10 grams and lives entirely on nectar and pollen, the only mammal outside the bats known to do so. It is found only in the far southwest of Western Australia, where it climbs through banksias and other heath shrubs, lapping nectar with a long tongue tipped in brush-like bristles. Pollen clings to its snout and fur as it feeds, making it an important pollinator of plants such as Banksia attenuata, Banksia coccinea and Adenanthos cuneatus. With no other food to fall back on, it relies on heath diverse enough to have something in flower all year, so frequent or intense fires and the plant disease Phytophthora cinnamomi threaten it and its plants together.
