These small apes belong to genus Nomascus which are found in Vietnam, Laos, Cambodia and southern China. The Hainan Gibbon is known to live in a restricted area of less than 100 km2 in southern China. They are known to communicate in species-specific song when defining territory or attracting mates. They sing in regional accents to each other and they form polygamous relationships.

The Hainan Gibbon lives in montane rainforest, at altitudes ranging from 650 to 1,200 m (Chan et al. 2005), although specimens were collected at lower elevations prior to the complete clearance of lowland forest on Hainan. It is diurnal, arboreal, and mostly frugivorous. The Hainan Gibbon is listed as Critically Endangered because of an observed decline of at least 80% over the past 45 years (three generations), primarily due to hunting and habitat loss (Mootnick et al. 2012, Turvey et al. 2015); its extent of occurrence is less than 100 km2 (Bryant et al. 2016)
