Tlacuache sureño

<em>Didelphis marsupialis</em> is a medium-sized marsupial in the family Didelphidae, widely distributed across the Neotropical region, including Colombia, Ecuador, Venezuela, Dominica, Grenada, and Saint Lucia. It inhabits tropical and subtropical moist broadleaf forests, often occurring near human settlements, gardens, and agricultural edges across lowland and montane zones. As a generalist omnivore, this species typically consumes fruits, invertebrates, small vertebrates, carrion, and refuse, making it one of the most adaptable mammals in its range. The common opossum is nocturnal and arboreal, using a prehensile tail for balance and grip while foraging in trees and shrubs. Females give birth to highly altricial young that develop in the marsupium, a defining trait of marsupial reproduction. The IUCN currently classifies this species as Least Concern, reflecting its broad distribution, behavioral flexibility, and tolerance of disturbed habitats. Biological traits such as average lifespan, body length, and body weight are not consistently recorded across populations in standardized databases, and detailed dietary studies remain poorly documented at scale. Its ecological role includes seed dispersal and control of invertebrate populations.
