Pygmy marmoset size: How big do they get?

How big does a Pygmy marmoset get? Here is an overview over the average adult age:

A grown Pygmy marmoset (Callithrix pygmaea) reaches an average size of 15.5 cm (0′ 7″).

When born, they have an average size of 0 cm (0′ 0″). During their lifetime of about 15.08 years, they grow from 14 grams (0.03 lbs) to 124 grams (0.27 lbs). A Pygmy marmoset has 2 babies at once. The Pygmy marmoset (genus: Callithrix) is a member of the family Callitrichidae.

As a reference: Humans reach an average body size of 1.65m (5′ 5″) while carrying 62 kg (137 lbs). A human woman is pregnant for 280 days (40 weeks) and on average become 75 years old.

The average adult size of a Pygmy marmoset is  (0' 7

The pygmy marmoset (Cebuella pygmaea) is a small species of New World monkey native to rainforests of the western Amazon Basin in South America. The species is notable for being the smallest monkey and one of the smallest primates in the world, at just over 100 grams (3.5 oz) (Madame Berthe’s mouse lemur is smaller). It is generally found in evergreen and river-edge forests and is a gum-feeding specialist, or a gummivore.About 83% of the pygmy marmoset population lives in stable troops of two to nine individuals, including a dominant male, a breeding female, and up to four successive litters of offspring. The modal size of a standard stable troop would be six individuals. Although most groups consist of family members, some may also include one or two additional adult members. Members of the group communicate using a complex system including vocal, chemical, and visual signals. Three main calling signals depend on the distance the call needs to travel. These monkeys may also make visual displays when threatened or to show dominance. Chemical signaling using secretions from glands on the chest and genital area allow the female to indicate to the male when she is able to reproduce. The female gives birth to twins twice a year and the parental care is shared between the group.The pygmy marmoset has been viewed as somewhat different from typical marmosets, most of which are classified in the genera Callithrix and Mico, and thus is accorded its own genus, Cebuella, within the family Callitrichidae. It is listed as Vulnerable by the International Union for Conservation of Nature. The biggest threats to the species are habitat loss and the pet trade.
