At just eight inches tall and weighing in at just 800 grams London Zoo's tiny new baby monkey has already made a big impression.
The three-week-old Sulawesi crested macaque (Macaca nigra) was born to 17-year-old Winoo after a 174-day-long pregnancy.
The infant is expected to triple its weight before autumn this year.
The critically-endangered monkey, who is yet to be named, is being nursed by mum Winoo and will be for at least another six months before gradually moving on to a diet of fruit, leaves and insects.
Fathered by dominant male Gaston, the infant is the latest addition to the eight-strong troop of Sulawesi crested macaques at the Zoo.
Zookeepers are yet to determine the gender of the baby who stands out from the adults, with its pale features and blue eyes.
The new-born’s eyes will darken with age, and the macaque’s iconic crest of hair will soon appear.
An important addition to the European breeding programme for endangered species (EEP), Sulawesi crested macaques are under constant threat in the wild from habitat loss and poaching.
