A pair of eastern pygmy marmosets, one of the smallest primate species on Earth, have been born at Chester Zoo.
The twins, each measuring just two inches (five centimetres) in length and weighing no more than 10 grams, arrived to parents Zoe and Baldrick.Keepers say the babies are already “highly inquisitive” but are so small that it will be some time yet until their genders are known.
“Mum Zoe and dad Baldrick have jumped straight into parenthood. Zoe is ever so caring and, unlike other primates, dad is heavily involved in the upbringing of the youngsters. Baldrick sensed that Zoe was ready to give birth and even put on a little extra weight to give him the energy to care for the twins. He’s really got stuck into the parenting - we spotted him carrying the babies around on his back when they were just one day old.“New babies always strengthen family bonds and some of the younger primates in the group have also been carrying the new arrivals around. It’s great to see them learn and pick up parenting tips from Zoe and Baldrick, and that experience will be important if they one day go on to have young of their own. The fact that younger members of the family are trusted to carry around such delicate new-borns, builds a lot of trust within the group.“The babies are already very inquisitive and aware of their surroundings. I can’t wait to see them develop their own little personalities.”
The eastern pygmy marmoset is native to the rainforests of western Brazil, south-eastern Colombia, eastern Ecuador and eastern Peru. These miniature monkeys are threatened by habitat loss and often exposed to hunting or their capture for the illegal pet trade.
Pygmy marmosets are social animals, have one mate for life and their tails are longer than their bodies, which helps keep them balanced as they pass from branch to branch through the forest. They grow to around eight inches long and weigh just 130g.
