Trichosurus

Description

The brushtail possums are the members of the genus Trichosurus in the Phalangeridae, a family of marsupials. They are native to Australia, Tasmania and some small nearby islands. Unique among marsupials, they have shifted the hypaxial muscles from the epipubic to the pelvis, much like in placental muscles, meaning that their breathing cycle is more similar to the latter than to that of other non-eutherian mammals. In general, they are more terrestrially oriented than other possums, and in some ways might parallel primates.
