Southern River Otter
Lontra provocaxAlso known as South American River Otter, Huillín, Patagonian River Otter
Southern river otters navigate the cold, fast-flowing rivers, fjords, and marine channels of Patagonia with remarkable agility, using their webbed feet and muscular tails to hunt. These elusive mustelids live in small family groups or as solitary hunters, seeking shelter in dense riparian vegetation and rocky crevices along the shoreline. Their presence serves as a vital indicator of healthy, undisturbed aquatic ecosystems in southern Chile and Argentina.

Endangered due to severe habitat loss, river fragmentation, and historical poaching for their dense fur.
Maintain a distance of at least 50 meters and avoid disturbing shoreline vegetation where they den.- Scan the shorelines: Look for active otters during early morning or late afternoon in quiet, vegetated river bends.
- Listen for vocalizations: Listen for high-pitched chirps, whistles, or warning snorts near the water's edge.
