How many babies does a Kloss’s gibbon have at once? (litter size)

How many baby Kloss’s gibbons are in a litter?

A Kloss’s gibbon (Hylobates klossii) usually gives birth to around 1 babies.

Each of those little ones spend around 207 days as a fetus before they are released into the wild. Upon birth, they weight 1.02 kg (2.24 lbs) and measure 8.5 cm (0′ 4″). They are a member of the Hylobatidae family (genus: Hylobates). An adult Kloss’s gibbon grows up to a size of 51.2 cm (1′ 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.

Kloss’s gibbon (Hylobates klossii), also known as the Mentawai gibbon or the bilou, is an endangered primate in the gibbon family, Hylobatidae. It is identifiable in that it is all black, resembling the Siamang with its black fur, but is considerably smaller and lacks the Siamang’s distinctive throat pouch. Kloss’s gibbon reaches a size 44 to 63 cm and weigh at most 6 kg. As is the case for all gibbons, they have long arms and no tail.Kloss’s gibbon exclusively lives on the Mentawai Islands that lie to the west of Sumatra. It is a diurnal inhabitant of the rain forest that hangs in the trees from its long arms and rarely comes to the ground. Like all species of gibbons it lives together in pairs that stake out a territory from approximately 20 to 30 hectares of size. This area is defended vehemently against other gibbons. Its diet consists mainly of fruits, occasionally also eating different plant parts, bird eggs, insects and small vertebrates.The singing of the female Kloss’s gibbon is considered the most beautiful of all the gibbons’ songs. Unlike most other gibbon species (except for the Javan silvery gibbon, Hylobates moloch), Kloss’s gibbon males and females do not sing duets. Males typically sing in the hour before sunrise, while an all-female chorus occurs after sunrise. The singing of the gibbons serves to warn off other animals from their territory, and possibly to strengthen the family bonds.The reproductive cycle of Kloss’s gibbon is similar to that of other gibbons. Every two to three years the female may give birth to a single young (with a gestation period of seven months). The young is weaned in the middle of its second year, and is fully mature in about seven years. Their life expectancy is about 25 years in the wild, and up to 40 years in captivity.
