Sulawesi Bear Cuscus

Ailurops ursinus

Also known as Sulawesi Bear Phalanger, Bear Cuscus

Sulawesi bear cuscus move deliberately through the high rainforest canopy, anchoring themselves with a long, muscular prehensile tail while stripping mature leaves from treetops. Active during the day, these primitive marsupials often travel in monogamous pairs, resting motionless for long hours to digest their low-energy foliage diet. Widespread deforestation and illegal hunting present severe pressures across their native Indonesian island strongholds.

Why interaction risk is low
Sharp claws and strong jaws can inflict wounds if cornered; observe quietly from a distance.
What to notice
Recognized by dark greyish-black thick fur, a long prehensile naked-tipped tail, and round bear-like facial features.
Support conservation
Never buy wild-caught individuals or reveal precise nest locations to protect remaining populations from illegal collection.
Responsible observation
  • Spotting in the Canopy: Look for slow, deliberate movements high in forest trees during early morning hours.
  • Maintaining Distance: Keep a respectful distance beneath roosting trees to avoid causing stress or disruption.
  • Recognizing Calls: Listen for quiet grunt-like vocalizations exchanged between pairs moving through the branches.
