Worlds smallest monkey born at Chester Zoo

The tiny infant, who has yet to be named or sexed, will measure only five inches in length and weigh up to just 150 grams when fully grown.

The little youngster arrived to mum Audrey (6) but, aside from doing the feeding, female Eastern pygmy marmosets are known to do none of the parental care and so the mini monkey is being carried around by dad, Gumi (7).

The South American primates are native to the forests of Brazil, Ecuador and Peru where they are threatened by habitat destruction and their capture for the pet trade

Despite their tiny stature, pygmy marmosets make a lot of loud noises – their whistles and squeals can be heard throughout the rainforest.

The species has specialised diets which includes insects, fruit and tree sap.
