Bare-tailed Woolly Opossum

Fascinating facts about the Bare-tailed Woolly Opossum

• Gestation lasts just 25 days, the longest known for any didelphimorph marsupial, after which the tiny joey remains in the mother's pouch for three months before emerging. Once out, it stays in the nest for another month while the mother continues to nurse, and weaning is completed at four months of age. The species can produce litters of one to seven young, each born weighing about 200 mg, and the mother builds dry-leaf nests in tree cavities to protect them.
• Its prehensile tail works like an extra limb, letting the opossum grip branches, avoid falls and haul leaves for nest construction. Researchers observed the tail acting as an additional limb for locomotion, which helps the animal navigate the canopy and prevents accidental drops. By using the tail to carry dry leaves, the opossum can assemble sturdy nests inside tree cavities, enhancing the safety of its solitary offspring.
• Males cut their nightly activity as moonlight brightens, dropping from new moon to full moon, while females keep a steady pace regardless of lunar phase. The study found that male activity declined with increasing exposure to moonlight, whereas female activity remained largely unaffected. This pattern shows that lunar illumination influences the foraging behaviour of males but not of females, likely reflecting differing risk-avoidance strategies.
• In French Guiana's primary forest each individual typically occupies about three hectares. In a primary forest of French Guiana, the mean home range size was calculated as 3 hectares (0.012 sq mi).
• Newborns weigh only 200 mg and grow to roughly 11 g by weaning. Newborn weigh 200 milligrams (0.0071 oz), and their weight increases to 11 grams (0.39 oz) after weaning.
