How much does a Northern white-cheeked gibbon weight?

It is hard to guess what a Northern white-cheeked gibbon weights. But we have the answer:

An adult Northern white-cheeked gibbon (Nomascus leucogenys) on average weights 7.32 kg (16.14 lbs).

The Northern white-cheeked gibbon is from the family Hylobatidae (genus: Nomascus). It is usually born with about 497 grams (1.1 lbs). When reaching adult age, they grow up to 54.5 cm (1′ 10″).

As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.

The northern white-cheeked gibbon (Nomascus leucogenys) is a species of gibbon native to South East Asia. It is closely related to the southern white-cheeked gibbon (Nomascus siki), with which it was previously considered conspecific. The females of the two species are virtually indistinguishable in appearance.The genome of N. leucogenys was sequenced and published in 2011.A “substantial” population of 455 critically endangered northern white-cheeked crested gibbons has been recently found living in the Pù Mát National Park in Nghệ An Province, northern Vietnam, near the border with Laos. Conservation International report they are living at high altitudes, and far from human settlements. This population, representing two-thirds of the total known in Vietnam are, apparently, the “only confirmed viable population” of this variety in the world.
