Habitat
Southern river otters primarily inhabit freshwater rivers, lakes, and wetlands in southern Chile and Argentina, favoring areas with clear water and abundant vegetation for cover. They are adaptable to various elevations but prefer unpolluted, slow-moving waters with nearby forests for denning. This species avoids heavily urbanized or degraded environments.
Diet
Southern river otters mainly eat fish such as trout and perch, supplemented by crustaceans, amphibians, and occasionally birds. They are opportunistic hunters that use their sensitive whiskers to detect prey underwater, typically feeding at dawn and dusk. Their feeding behavior involves diving and chasing prey in shallow waters.
Behavior
Southern river otters are mostly solitary animals, coming together only for mating, and they establish territories along riverbanks marked with scent from anal glands. They are diurnal, most active during early morning and late afternoon, spending much of their time swimming, playing, or resting in dens. These otters exhibit playful behaviors like sliding on riverbanks and are known for their vocalizations to communicate with others.
Conservation Status
The IUCN status of the Southern river otter is Endangered, with populations declining due to habitat destruction, water pollution, and overhunting. Major threats include human encroachment and competition from invasive species.
