The proboscis monkey or long-nosed monkey, known as the Bekantan in Malay, is a reddish-brown arboreal Old World monkey that is endemic to the south-east Asian island of Borneo.
It belongs in the monotypic ironically named genus Nasalis.
The monkey also goes by the Malay name monyet belanda meaning Dutch monkey, or even orang belanda literally meaning Dutchman, as Indonesians remarked that the Dutch colonisers often had a similarly large overfed looking pot-belly and big red drinking nose.
