Saimiri sciureus
Note high Gothic arch. Could also be S. oerstedii or S. ustus. Precise identification requires both phenotypic and karyotypic examination.
- Body weight < 1 kg
- Males 25-30% larger than females
- Males and females undergo seasonal reproductive changes, from infertility or anestrus to fertility, with corresponding low and high sex hormone levels
- Males undergo fatting and testes enlargement
- Have free/unbound cortisol ~100X that of humans or OWPs

- Describe the chromosome number in squirrel monkeys.
2n = 44
Vary in number of acrocentric chromosomes (5-7), thought to be due to pericentric inversions.
Karyotyping is critically important because:
- Species and subspecies vary in susceptibility to both naturally and experimentally-induced disease.
- Interbreeding between different species or subspecies can lead to heterozygosity for pericentric inversions leading to non-viable gametes due to meiotic cross-over events at the inversion. Up to 50% of hybrid squirrel monkey conceptions could be non-viable.

Cotton-topped tamarin (endangered)
Sanguinus oedipus

- Marmosets and tamarins usually housed in pairs or small family groups
- Narrow, high cages preferable to larger floor space with less height since callitrichids spend little time on the floor.
- Multiple feeding stations for callitrichids are needed and should be above floor if housing > 1 animal per cage. Food guarding can contribute to wasting syndrome.
