binomial_authority = (Miller, 1903)Kloss's Gibbon ("Hylobates klossii"), also known as the Mentawai Gibbon or the Bilou, is a
primate in theHylobatidae orgibbon family. It resembles theSiamang with its blackfur , 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 ofSumatra . It is a diurnal inhabitant of therain 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 offruit s, occasionally also eating different plant parts, bird eggs, insects and small vertebrates.The singing of Kloss's Gibbon is considered the most beautiful of all the gibbons' songs. Males and females will sing at considerable length either singlely or in duets, particularly during the morning and evening. 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.
