Litter Size

How many babies does a Siamang have at once? (litter size)

How many baby Siamangs are in a litter?

A Siamang (Symphalangus syndactylus) usually gives birth to around 1 babies.

Each of those little ones spend around 230 days as a fetus before they are released into the wild. Upon birth, they weight 517 grams (1.14 lbs) and measure 1.7 cm (0′ 1″). They are a member of the Hylobatidae family (genus: Symphalangus). An adult Siamang grows up to a size of 82.4 cm (2′ 9″).

To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.

The average litter size of a Siamang is 1

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.
