The cutest twins ever? World's smallest monkey, the pygmy marmoset, gives birth to two adorable babies weighing just 15 GRAMS Pygmy marmosets, Iti and Gomez - the world's smallest species of monkey - have become the proud parents of two twins weighing just 15 grams.
The tiny pygmy marmoset monkeys were welcomed to the family at Symbio Wildlife Park in Helensburgh, south of ‪‎Sydney‬.

The new arrivals look miniature, compared to their mother Iti who has to carry them around, but these babies are heavy for her.
‘Although 15 grams may seem tiny, if you put into perspective it is actually relative to a human giving birth to a ten year old child,’ wrote Symbio Wildlife Park alongside the video.
