The Sulawesi bear cuscus, also known as the Sulawesi bear phalanger (Ailurops ursinus), is a species of arboreal marsupial in the family Phalangeridae that is endemic to Sulawesi and nearby islands in Indonesia. It lives in tropical moist lowland forest at elevations up to 600 m (2,000 ft) and is diurnal, folivorous and often found in pairs.^[2] A. ursinus is threatened by hunting, collection for the pet trade and deforestation.^[2]
