This July, Symbio Wildlife Park welcomed two tiny twins from the world’s smallest species of monkey, the pygmy marmoset.The pair, weighing in at just 15 grams each, are just starting to raise their heads to look at the world, albeit whilst tightly clinging to their mum’s back.New bubs Jo and Gomez join a family of five older siblings, who will, per marmoset nature, all chip in to look after the newest additions to the family.
