The Hairy-nosed Otteris the rarest and least known among the five species of otters occurring in Asia. Once believed to be extinct, it has been rediscovered in different parts of South-east Asia such as Cambodia (Tonle Sap wetlands), Malaysia (Terengganu and Maur), Sumatra, Thailand (Phru Toa Daeng Peat Swamp Forest), and Viet Nam (U Minh Thuong Nature Reserve in Mekong Delta). Historically it has also been reported from Brunei, Myanmar, and Penang Island. Very little is known about the Hairy-nosed Otter, but it is likely that it is threatened by destruction of peat swamp forests for logging and agriculture. Research is critically needed on all aspects of this species’ ecology and biology. Bibliography. Banks (1949), Francis (2008), IUCN (2008), Lekagul & McNeely (1991), Medway (1969), Nguyen et al.
