Honey possum
The honey possum (Tarsipes rostratus), also known by the native names tait and noolbenger, is a tiny Australian marsupial. It is the only species in the genus Tarsipes and in the family Tarsipedidae.
Many authorities believe it is sufficiently distinct to be more properly raised to a separate superfamily within the Diprotodontia, or perhaps even further. It is thought to be the sole survivor of an otherwise long-extinct marsupial group.
It is an important pollinator for such plants as Banksia attenuata, Banksia coccinea or Adenanthos cuneatus.
