14 DAY TRIAL // Keepers at Belfast Zoo in northern Ireland are happy to announce that a pair of twin baby pygmy marmosets born at this facility about a month and a half ago, on November 14, are growing stronger every day and are making progress towards becoming independent.
Information shared with the public says that, for the time being, the baby primates still spend most of their time holding tight to their parents' body and expect to be carried around by them.
However, it appears that they are growing more adventurous as the days go by, and that it will probably not be very long until they set out to explore their enclosure on their own.
Zoo Borns tells us that this species is native to South America's upper Amazon basin. For the time being, the International Union for Conservation of Nature considers pygmy marmosets to be a species of least concern, meaning that these primates are not in danger of going extinct.
According to the same source, adult pygmy marmosets weight merely 4-5 ounces (110-140 grams) when fully developed. This makes them some of the world's smallest primates.
