Big male proboscis monkey

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 genus ''Nasalis'', although the pig-tailed langur has traditionally also been included in this genus. This species of monkey is easily identifiable because of its unusually large nose.
