A rare King colobus monkey has been born at Paignton zoo in Devon.
The animal, which has not been named yet, was born on Saturday to proud parents Martin and Ivy.
The baby is currently pure white but will eventually develop the distinctive black markings of the King colobus when it is about a month old.
King colobus monkeys, which weigh less than 1kg at birth, mainly eat leaves and spend all of their lives in tree tops.
Monkeys at a zoo have been banned from eating bananas - because they are deemed too sugary.
Zoo keepers at Paignton Zoo in Devon say the banana ban has let to an improvement in the colour and thickness of the monkeys' coats, as well as calming the more aggressive animals.
An animal nutritionist likened bananas to the primate equivalent of eating "cake and chocolate" because fruit grown for human consumption is higher in sugar and lower in protein and fibre than most wild fruit.
Amy Plowman, head of conservation and advocacy, said: "Compared to the food they would eat in the wild, bananas are much more energy-dense - they have lots of calories - and contain much more sugar that's bad for their teeth and can lead to diabetes and similar conditions.
"It can also cause gastrointestinal problems as their stomachs are mostly adapted to eating fibrous foods with very low digestibility."
