Story time: Scientists have observed monkeys in the South American rainforest. These monkeys eat Brazilia Nuts off trees. The shell is too hard to bite open. These monkeys have found they can use a rock to smash the nut on the ground to open it. Story time: Scientists have observed monkeys in the South American rainforest.
