One of the 12 female squirrel monkeys that came to the Taronga Zoo in July has already gave birth to a baby monkey. 

The baby adorably clings onto his mother's back at the Australian zoo. Like all squirrel monkey babies he will do this until he can explore on his own, according to a zoo news release. 

The monkeys came to the zoo from France and are part of a regional breeding program, reported Zoo Borns. 

The baby monkey, Julio, was born to squirrel monkeys Lina and Chico. 

"Lena and baby are doing amazingly well," Taronga Zoo primate keeper Suzie Lemon told Zoo Borns. "A lot of the female Squirrel Monkeys have been interacting with the baby, and our two oldest Squirrel Monkeys, 'Ayaca' and 'Squirius', have been showing a lot of interest by vocalizing at him and rubbing up against him." 

Out of all the monkeys in the wild, the squirrel monkey is the smallest. They travel in groups of about 500 and are found in Central and South America. 

Below are some pictures the zoo took of Julio clinging to his mom's back:
