Perth Zoo has had another breeding success with twin Pygmy Marmosets born on 19 January 2011. The infants were born to parents Mia and Mario and are now starting to venture off their parents' backs and explore their exhibit. Pygmy Marmosets are the world's smallest monkeys and adults grow to weigh under 5 ounces!
