Habitat

This species primarily inhabits freshwater rivers, swamps, and wetlands in tropical regions of Southeast Asia, including parts of Indonesia, Malaysia, and Thailand. They prefer areas with dense riparian vegetation and slow-moving waters for easy access to food and shelter. These habitats are often threatened by human development.

Diet

The Hairy-nosed otter mainly feeds on fish, crustaceans, and amphibians, which it catches by diving in shallow waters. It is an opportunistic feeder, also consuming small mammals and birds when available, and typically hunts at night or during twilight hours. Feeding behavior involves quick, agile swims to pursue prey.

Behavior

Hairy-nosed otters are primarily nocturnal and semi-aquatic, spending much of their time in water but resting in dens along riverbanks. They live in small family groups with a hierarchical structure and are territorial, marking their areas with scent to ward off intruders. These otters are playful and vocal, using a variety of calls for communication.

Conservation Status

The IUCN status of the Hairy-nosed otter is Endangered, with populations declining due to habitat loss from deforestation and pollution. Major threats include human encroachment and illegal wildlife trade.
