It is hard to guess what a Common marmoset weights. But we have the answer:
An adult Common marmoset (Callithrix jacchus) on average weights 291 grams (0.64 lbs).
The Common marmoset is from the family Callitrichidae (genus: Callithrix). It is usually born with about 27 grams (0.06 lbs). They can live for up to 16.75 years. When reaching adult age, they grow up to 24 cm (0′ 10″). Usually, Common marmosets have 2 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
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.
