Pygmy marmosets are omnivores, meaning they eat both plants and insects. Their diet consists of fruits, tree sap, nectar, and small insects like spiders and grasshoppers.
Pygmy marmosets have a lifespan of around 12 years in the wild and up to 20 years in captivity.
Yes, pygmy marmosets are considered to be near threatened on the IUCN Red List due to habitat loss and fragmentation. They are also often captured and sold as exotic pets, which further threatens their population.
