Finger Monkey/Pocket Monkey

The name “finger monkey” or sometimes “pocket monkey” isn’t exactly a scientific name or even a common name for a particular monkey, it’s just a monkey that can cling to somebody’s finger or fit in a shirt pocket. Mostly, however, what has popularized the idea of a finger monkey are some images that have come out from zoos and rescue centers of baby pygmy marmosets clinging to the fingers of caretakers.
