The adorable rare monkey has been cared for by its mother Lisa since it was born on April 17.

Here are the first pictures of the eight-day old youngster, which is yet to be named or identified as male or female.

Mum Lisa cradles the newborn protectively as she balances on a branch in the zoo enclosure.

Sulawesi crested macaques are one of the world's most endangered primates. They are considered a delicacy in their homeland and are served up at special occasions such as weddings.

It's estimated there are fewer than 5,000 on their native island of Sulawesi in Indonesia, with wild numbers believed to have plummeted by around 80% in the last 30 years.

Favouring a largely vegetarian diet, full-grown Sulawesi crested macaques maintain relationships by grooming one another and communicating with grunts, smacking their lips as a greeting sign.

Adult males tend to yawn - not because they are tired but to display their large teeth to ward off conflict.

Dr Nick Davis, Chester Zoo's assistant curator of mammals, said: "We're looking forward to seeing what sort of character our tiny youngster will develop into. At the moment though, our new arrival will spend time playing and getting to know the rest of the group."
