Common Marmosets (Callithrix jacchus) are small, Old World
monkeys that are native to northeast Brazil. The species has established
outside its native range following introduction into the Brazilian
states of Bahia, Espirito Santo, Parana, Rio de Janeiro, Santo Catarina,
Sao Paulo and Sergipe; and Buenos Aires in Argentina. No major impacts
of establishment have been noted.
Common Marmosets are unlikely to establish in Tasmania. Climate
modelling indicates that Tasmania has a highly dissimilar climate which
would not readily support this species.
Common Marmosets are listed as 'Least Concern' under the IUCN Red List.
The species is relatively widely distributed, adaptable, and occurs in a
number of protected areas. Common Marmosets are commonly used in
biomedical research in Europe and the United States of America.
As primates, Common Marmosets are listed under Appendix II of the
Convention on International Trade in Endangered Species of Wild Fauna
and Flora (CITES). The trade of this species is controlled under this
Under the Environment Protection and Biodiversity Conservation Act 1999,
Common Marmosets are listed as 'specimens taken to be suitable for live
import' and require a permit to import under this Act. Eligible imports
are for non-commercial purposes only (i.e. zoos) and exclude household
In Tasmania, Common Marmosets are 'controlled animals' under the Tasmanian Nature Conservation Act 2002.
The species is classed as an 'extreme' threat under the Vertebrate Pest
Committee's list of exotic animals. The assessment notes that the
species is kept in some private zoos and approval has been given for
breeding according to breeding management plans.
This risk assessment concludes that Common Marmosets (Callithrix jacchus)
are a moderate threat to Tasmania and recommends that imports be
restricted to those license holders approved for keeping moderate threat
