Species of marsupial

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]

When approached, their automatic reaction is to wrap their tail around a nearby branch and switch from tripedal and bipedal posture with their foreleg raised. While doing these movements, they're constantly making short, harsh sounds.[3]

Bear cuscuses can feed on the young leaves of up to 31 different species of plants varying from trees, lianas, and mistletoes.[4] Feeding only amounts to about 5% of their daily activity, compared to about 63% spent on resting.[4]
