subfamily Callitrichinae contains the marmosets, tamarins and Goeldi's
monkey. These neotropical primates are the smallest New World
anthropoids (under 1 kg). They have secondarily derived claws on all
digits but the hallux, presumably advantageous for climbing large
(relative to body size) tree trunks for feeding on insects, gums, and
saps. Additionally, members of the Callitrichinae are known for their
2.1.3.2 dental formula, indicating the loss of one set of molars.
Postcranially, they have relatively long trunks, tails, and legs. They
are also known for their reproductive biology as many species of
Callitrichinae commonly produce twins, and parental care is shared by
both sexes.</p>
