Keep these fun facts in mind the next time someone tells you to stop "monkeying around:"

  A group of monkeys may be referred to as a mission of monkeys or a tribe of monkeys.
• The name "monkey" may come from a German version of the Reynard the Fox fable, published in around 1580
• New World monkeys form monogomous pair bonds
• Most monkeys have prehensile tails, which can act as a "fifth hand" (full) or aid solely in dangling from objects (partial) . The term prehensile literally means "able to grasp"
• Capuchin monkeys have only partially prehensile tails.
• Marmosets & tamarins – both New World monkeys – don’t have prehensile tails.
• Natasha is the name of a macaque that has become well known because, unlike other macaques who move by alternating between walking upright and on all four limbs, Natasha walks upright all the time, since suffering from a stomach flu that almost killed her.
