Infraclass: Marsupialia —> Order: Diprotodontia —> Family: Tarsipedidae
Honey possums are super cute and super tiny possums, only growing to about 6.5 cm to 9 cm, and are the only members of the Family Tarsipedidae.
Its range is pretty restricted, only a fairly small range in the Western Australia’s south west portion, but there the honey possum is actually rather common, and is probably not at any real risk of extinction (provided the habitat goes undisturbed).
Honey possums are one of the few entirely nectarivirous mammals, with a long pointed snout and a long tongue with a brush-tip, to gather pollen and nectar. It has fewer teeth than most other marsupials (only 11 teeth, which are all very small).
They tend not to form large groups, always keeping the number below 10 - this greatly reduces the amount of fighting they might do (though, the mental image of little teeny possums fighting is pretty adorable).
