Range and habitat

This hairy-nosed otter occurs in Southeast Asia from southern Thailand, Cambodia, southern Vietnam and Peninsular Malaysia to Sumatra and Borneo. In Thailand, it was recorded in the Pru Toa Daeng peat swamp forest and in areas around the Bang Nara river. It mainly habits lowland flooded forests with climaxing vegetation in three levels: a primary forest zone, a secondary forest zone made up of Melaleuca cajuputi, and a third zone of grasslands.

Diet and breeding

The hairy-nosed otter occurs in coastal areas and on larger inland rivers, solitary or in groups of up to four. Its diet includes fish, such as broadhead catfish, snakeheads, and climbing perch, and water snakes, mollusks, and crustaceans.

During the dry season, individuals forage in drainage canals and ponds. Pairing of a male and a female may be limited to the breeding period. Populations in Cambodia breed between November and March.

In crisis

It is threatened by loss of natural resources and poaching. The hairy-nosed otter is threatened by the loss of natural resources and poaching. The hairy-nosed otter is the rarest otter in Asia, most likely verging on extinction in the northern parts of its range and of uncertain status elsewhere.

Only a few viable populations remain, widely scattered in region. The species is threatened by loss of lowland wetland habitats, hunting for fur and meat, and accidental killing during fishing.

CITES lists this taxon on Appendix II. Confirm the current appendix on the CITES checklist.
