The endangered Numbat only eats termites - up to 20,000 a day! It is well equipped for a life of snacking on termite with well-developed sense of smell to locate the shallow and unfortified underground galleries that termites construct between the nest and their feeding sites, strong claws to rip into these galleries and a long snout and long sticky tongue which is flicks out in search of those oh so tasty morsels.
The Gilbert's potoroo (Potorous gilbertii) is the most endangered mammal in Australia. This small marsupial, also known as the rat-kangeroo, only survives in one location - Two Peoples Bay Nature Reserve in southwestern Australia. The small animal eats mostly mushrooms and is threatened by feral foxes and cats and the possibility of fire. One fire could destroy the entire remaining population.

An Australian Honey Possum - a marsupial about half the size of a mouse, feeds on a Mottlecah Eucalyptus. It is an important pollinator for such plants as Banksia attenuata, Banksia coccinea or Adenanthos cuneatus.
