Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Long-Tailed Otter faces severe pressure from habitat destruction as wetlands across its range are drained for agriculture and urban development. Water pollution from mining, industrial discharge, and agricultural runoff degrades the aquatic ecosystems this species depends on for hunting fish and crustaceans. Hunting for pelts and traditional medicine continues in some regions, while dam construction fragments river systems and disrupts the otter's movement patterns between territories.

Threat summary

Habitat

Long-Tailed Otters inhabit freshwater systems including rivers, streams, lakes, and marshes from Mexico through Central America to South America.
