Habitat
The water opossum inhabits freshwater environments such as rivers, streams, and marshes in Central and South America. It prefers areas with dense riparian vegetation for cover and hunting. These habitats range from lowland forests to higher elevation waterways up to 2,000 meters.
Diet
The water opossum primarily eats fish, frogs, crustaceans, and aquatic insects, which it catches by diving and swimming. It hunts nocturnally, using its sharp claws and teeth to grasp prey in shallow waters. Feeding behavior includes foraging along riverbanks and in vegetation.
Behavior
Water opossums are solitary and nocturnal, spending their nights hunting in water and resting in dens during the day. They are excellent swimmers and divers, using their webbed feet to navigate rivers efficiently, and they mark territories with scent glands. They exhibit pouch care for young and are generally elusive, avoiding human contact.
Conservation Status
The IUCN classifies the water opossum as Least Concern, with a stable population trend across its range. Major threats include habitat loss from deforestation and water pollution.
