A pair of tiny marmoset monkey twins are starting to explore their new home.
Born last month, they are the second set of twins born at Tynemouth’s Blue Reef Aquarium in less than a year.
The twins, which weighed less than 40 grammes each when they were born, spent the first few weeks of their lives clinging to the backs of their parents.
However the pair are now beginning to venture further afield, with the help of parents Minnie and Miko and their two older brothers – Rio and Gemeo.
Blue Reef’s Rosie Wiggin said: “The whole family are doing really well and working together to raise our newest arrivals.
“Minnie and Miko are much more confident and relaxed parents this second time round and the two brothers are helping out looking after them, carrying them round on their backs and grooming them.
“Miko actually began letting Rio and Gemeo carry them when they were about a fortnight old.”
“Typical of older brothers they are full of energy and quite active - jumping around a lot.
“At first this looked a little alarming but it’s definitely helping the babies’ coordination as they learn to hold on and it’s giving mum and dad a well-earned break.”
Marmosets live in social family groups and have a strict hierarchy ranking. Unusually for primates, females nearly always gives birth to non-identical twins.
The aquarium’s Amazing Amazon is home to a colony of three different types of New World monkeys; common and black-tailed marmosets and cotton top tamarins.
