'''Pygmy marmosets''' are two [[species]] of small [[New World monkey]]s in the genus '''''Cebuella'''''. They are native to [[Amazon rainforest|rainforests]] of the western [[Amazon Basin]] in South America. These primates are notable for being the smallest monkeys in the world, at just over {{convert|100|g|oz|abbr=on}}. They are generally found in [[evergreen forest|evergreen]] and [[riparian forest|river-edge forests]] and are [[gum (botany)|gum]]-feeding specialists, or [[gummivore]]s.

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.<ref name="Soini1988"/> 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 among the group.

The pygmy marmoset has been viewed as somewhat different from typical [[marmoset]]s, most of which are classified in the genera ''[[Callithrix]]'' (where they were placed in a subgenus)<ref name="MSW3"/> and ''[[Mico (genus)|Mico]]'', and thus is accorded its [[Monotypic taxon|own genus]], ''Cebuella'', within the family [[Callitrichidae]].  Their biggest threats are [[habitat destruction|habitat loss]] and the [[Wildlife trade|pet trade]].<ref>{{cite journal | doi = 10.1016/S0006-3207(99)00183-4 | volume=94 | title=Effects of human activities on wild pygmy marmosets in Ecuadorian Amazonia | year=2000 | journal=Biological Conservation | pages=153–163| last1=de la Torre | first1=Stella | last2=Snowdon | first2=Charles T. | last3=Bejarano | first3=Monserrat | issue=2 }}</ref>
