The rare newborn albino Pygmy Marmoset (Callithrix pygmae) monkey perches on a zookeeper’s thumb at Froso Zoo in Ostersund, Sweden August 22, 2006.
The Pygmy Marmoset, which lives in the upper Amazon basin in South America, is the world’s smallest monkey and reaches 35 cm (13.7 inches) in length and weighs up to 100 grams (3.5 ounces) at maturity.
Pygmies feed principally on arthropods (especially grasshoppers) and the exudates (sap and gum) of certain trees and vines.
Pygmies communicate using a variety of high pitched clicks, squeaks, whistles, and trills, and even a variety of complex body and facial gestures.
In captivity, the Pygmy Marmoset can live up to 11 years
