Pygmy marmosets are the world's smallest true monkey species with highly specialised gummivorous diets and complex family group structures requiring careful zoo management.
Pygmy marmoset welfare requires exceptional attention to diet, thermoregulation and group structure. Their highly specialist diet cannot be met by standard primate diets - gum supplementation, live insects and specialist primate diet are essential. Family group stability is critical - the cooperative care structure means that group disruption harms juvenile welfare through reduced care provision. Temperature and humidity control must prevent the cold stress that can rapidly affect these tiny animals.
