Tiny Team Of Squirrel Monkeys Are As Adorable As You'd Imagine

They cling to their mothers like fluffy little backpacks.

Meet four of Taronga Zoo's newest, fluffiest additions -- a team of squirrel monkeys.

They're too young to tell their gender, so they don't have names yet but primate keeper Janet Lackey said they were fitting right in.

"It's a very exciting time for the family group of 17 squirrel monkeys," Lackey said.

"We are starting to see the older babies venturing off mum's back and exploring the trees and ropes, and being very playful together.

"The youngest baby is still clinging tightly to mum as there is quite a big developmental difference between four and six weeks of age."

"We do have a first time mum in the group, little four-year-old Yamma, and she is doing so impressively well. We are really proud of her," said Janet.
