<p>This July, Symbio Wildlife Park welcomed two tiny twins from the world’s smallest species of monkey, the pygmy marmoset.</p><p>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.</p><p>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.
