The family Tarsipedidae is a small group of bats within the order Chiroptera, notable for containing only a single species, the honey possum bat (Tarsipes rostratus), native to southwestern Australia. Members of this family are specialized nectarivores, feeding primarily on nectar and pollen, and they play an important role as pollinators for many native plants. They are small, with elongated snouts and tongues adapted for accessing floral nectar, and exhibit behaviors and physiological adaptations that support a high-sugar diet, including rapid digestion and high metabolism. Tarsipedidae bats are solitary or found in small groups, roosting in tree hollows or dense foliage, and their specialized ecological niche makes them an interesting example of evolutionary adaptation among mammals.
