Pygmy marmoset

The pygmy marmoset is a tiny New World monkey native to western Amazonia. It specializes in gouging trees for sap and usually lives in small groups.

Gummivory: The feeding strategy of obtaining gum or sap from plants. Pygmy marmosets rely heavily on plant exudates, especially tree sap.
Callitrichidae: A family of small New World monkeys that includes marmosets and tamarins. The pygmy marmoset is the smallest living member of this primate family.
Primate cognition: The mental processes of primates, including learning, memory, and problem-solving. Pygmy marmosets are studied to investigate cognition in small-bodied primates.
Common marmoset: A small Atlantic Forest marmoset native to eastern Brazil. It is larger and has conspicuous ear tufts, unlike the pygmy marmoset.
Tree gouging: The scraping or cutting of bark to expose sap and other plant exudates. Pygmy marmosets make repeated gouges in trees to create sap-feeding sites.
New World monkey: A primate native to Central and South America, belonging to the parvorder Platyrrhini. This broader primate group provides the evolutionary context for the species.
Neotropical primate conservation: Efforts to protect primates native to Central and South America. Habitat loss and capture pressure make conservation relevant to the species.
Tamarin: A small New World monkey in the genus Saguinus or Leontocebus. Tamarins are close callitrichid relatives but are generally larger.
Dental adaptation: The evolutionary modification of teeth for particular feeding tasks. Its lower incisors form a tool for opening bark and reaching sap.
Amazon rainforest: A vast tropical rainforest system in the Amazon Basin of South America. Western Amazonian rainforest supplies the trees and habitat pygmy marmosets depend on.
