Pygmy marmosets are the smallest marmosets and one of the smallest of all primates.
Over 10 years.
Head and body length: 11-15cm, Tail length: 17-22cm, Weight: 120-190g.
Pygmy marmosets have tawny agouti fur (the tip of the hair is a different colour to the base) with an indistinctly dark-ringed tail.
They inhabit Brazil, Ecuador and Peru.
They live in flooded forest near rivers, bamboo thickets and the edges of agricultural fields.
Pygmy marmosets mainly feed on gum (tree exudates, sap), but they also eat fruit, nectar and animal prey. They gouge holes in the bark of trees, and revisit these holes daily to collect the sap.
Pygmy marmosets live in groups of about six members, which includes a monogamous male and female and the offspring of up to four litters. Sometimes there are two males, but one is dominant to the other and restricts access to the female. They are diurnal and arboreal, and are capable of jumping vertically up to 5m.
After a gestation period of 119-140 days, females give birth to two (rarely three) infants. The male carries the young.
Pygmy marmosets are not listed by the IUCN.
