What is the maximal age a Common marmoset reaches?
An adult Common marmoset (Callithrix jacchus) usually gets as old as 16.75 years.
Common marmosets are around 144 days in the womb of their mother. When born, they weight 27 grams (0.06 lbs) and measure 12.5 cm (0′ 5″). As a member of the Callitrichidae family (genus: Callithrix), their offspring is 2 babies per pregnancy. Fully grown, they reach a bodylength of 28 cm (1′ 0″).
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.
The common marmoset (Callithrix jacchus) is a New World monkey. It originally lived on the northeastern coast of Brazil, in the states of Piaui, Paraiba, Ceará, Rio Grande do Norte, Pernambuco, Alagoas and Bahia. Through release (both intentional and unintentional) of captive individuals, it has expanded its range since the 1920s to Southeast Brazil (its first sighting in the wild for Rio de Janeiro was in 1929), where it became an invasive species, raising concerns about genetic pollution of similar species, such as the buffy-tufted marmoset (Callithrix aurita), and predation upon bird nestlings and eggs.The whole-genome sequence of a female common marmoset was published on 20 July 2014. It became the first New World Monkey to have its genome sequenced.
