- ‘Fiber content in the diet of callitrichids is a subject of considerable discussion.’
- ‘It belongs to the family of callitrichids, which also encompasses the larger marmosets and the tamarins.’
- ‘When people first started looking at social systems and mating systems, they thought callitrichids were monogamous.’
- ‘The co-operative breeding system of callitrichids appears to be unique amongst primates, and serves to help the breeding female care for the offspring.’
- ‘The callitrichids are distinct from the cebids in having claws on most digits other than the great toe’
Late 18th century: from modern Latin Callitrichidae (plural), from Greek kallitrikhos beautiful-haired.
