The pygmy marmoset is the world’s smallest monkey. Found in the rainforests of the Amazon basin, these little critters will fight each other over trees in order to reach their favourite food; tree sap.
Despite its small stature, the pygmy marmoset isn’t lacking in clever adaptations for arboreal life. They can rotate their heads 180 degrees to look for danger, cling to branches with specialised claw-like nails, and leap 4.5 metres (15 feet) between trees.
Sadly, these incredibly cute primates are targeted by the pet trade, which is severely threatening the survival of wild populations and therefore the future of the species.
