Nectar-feeding marsupials, such as the honey possum and various pygmy possums, act as effective pollinators by visiting flowers to feed on nectar. As these small mammals forage, they inadvertently pick up pollen on their bodies, which is then transferred to other flowers they visit, facilitating the process of pollination.123

In Australia, these marsupials have evolved as flower specialists, playing a vital role in the reproduction of certain plant species, including some eucalypts. While many pollinators are insects or birds, these diminutive marsupials demonstrate the important, though less common, role that small mammals play in maintaining plant biodiversity through their feeding habits.231
