Litter Size

How many babies does a Pygmy marmoset have at once? (litter size)

How many baby Pygmy marmosets are in a litter?

A Pygmy marmoset (Callithrix pygmaea) usually gives birth to around 2 babies.

Each of those little ones spend around 134 days as a fetus before they are released into the wild. Upon birth, they weight 14 grams (0.03 lbs) and measure 12.5 cm (0′ 5″). They are a member of the Callitrichidae family (genus: Callithrix). An adult Pygmy marmoset grows up to a size of 15.5 cm (0′ 7″).

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.

The average litter size of a Pygmy marmoset is 2

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.
