How old does a Siamang get? (age expectancy)

What is the maximal age a Siamang reaches?

An adult Siamang (Symphalangus syndactylus) usually gets as old as 38 years.

Siamangs are around 230 days in the womb of their mother. When born, they weight 517 grams (1.14 lbs) and measure 4 cm (0′ 2″). As a member of the Hylobatidae family (genus: Symphalangus), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 82.4 cm (2′ 9″).

As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.

A Siamang gets as old as 38 years

The siamang (Symphalangus syndactylus) is an arboreal black-furred gibbon native to the forests of Indonesia, Malaysia and Thailand. The largest of the gibbons, the siamang can be twice the size of other gibbons, reaching 1 m in height, and weighing up to 14 kg. The siamang is the only species in the genus Symphalangus.Two features distinguish the siamang from other gibbons. The first is that two digits on each foot—the second and third toes—are partially joined by a membrane—hence the name “syndactylus”, from the Ancient Greek sun-, “united” + daktulos, “finger”. The second is the large gular sac (found in both males and females of the species), which is a throat pouch which can be inflated to the size of the siamang’s head, allowing it to make loud, resonating calls or songs.Two subspecies of the siamang may exist. If so, they are the nominate Sumatran siamang (S. s. syndactylus) and the Malaysian siamang (S. s. continentis, in peninsular Malaysia). Otherwise, the Malaysian individuals are only a population. The siamang occurs sympatrically with other gibbons; its two ranges are entirely within the combined ranges of the agile gibbon and the lar gibbon.The siamang can live to around 40 years in captivity.While the illegal pet trade takes a toll on wild populations, the principal threat to the siamang is habitat loss in both Indonesia and Malaysia. The palm oil production industry is clearing large swaths of forest, reducing the habitat of the siamang, along with that of other species, such as the Sumatran tiger.
