White-eared Opossum (Didelphis albiventris) lives in tropical rainforest across Central and South America. Its conservation status is Least Concern.
Fascinating facts about the White-eared Opossum
- White-eared opossums can tip the scales anywhere from a half-kilogram to nearly three kilograms, making them as light as a small sack of rice. Their size lets them slip into tight burrows and climb thin branches, expanding the range of habitats they can exploit. This flexibility helps them thrive in both wild savannas and suburban backyards, buffering populations against habitat loss.
- A female can give birth after just 12 to 14 days of gestation, then carries up to 23 newborns, though only 13 can latch onto the pouch's mammae, until they're old enough to cling to her back. The young stay in the pouch for two months, are weaned at 3-4 months, and reach sexual maturity around nine months.
- Their diet breaks down to 39% invertebrates, 28% vegetation, 17% birds, 12% fruits and seeds, and 4% unknown items, turning them into mobile seed-dispersal machines. Seeds from mulberries, passionflowers and other pioneer plants pass through their gut unharmed, emerging ready to sprout, which helps regenerate forests after disturbance.
- In Brazil's drying Caatinga, white-eared opossums are among the small mammals that make up 54% of the region's mammal species, and climate models predict that 91.6% of terrestrial mammal communities there will lose species by 2060. Their broad diet and habitat tolerance, but the loss of suitable climate space still threatens their long-term persistence.
- Each individual roams an average of 0.57 hectares, yet the range does not differ between males and females.

About the White-eared Opossum
In the twilight depths of the South American forest, the white-eared opossum navigates its domain with stealthy precision, its large, round eyes drinking in every detail of the shadows. With a delicate balance of caution and curiosity, it pads silently across the forest floor, its prehensile tail twitching like a counterweight as it explores the intricate web of tree roots and underbrush. As it moves, the faint gleam of its white-tipped ears catches the fading light, a fleeting glimpse of this enigmatic creature's quiet, nocturnal reign.
