ZSL London Zoo are celebrating the arrival of a black-capped squirrel monkey baby, which was born in the middle of the night, just under three weeks ago. Zoo keepers discovered the tiny bundle clinging tightly on to its mum during their morning rounds.
The baby monkey, which measures just three inches tall, was born after a six-month gestation period in the zoo's Meet the Monkey's exhibit.
Zookeeper Andrea Dempsey said: "Squirrel monkeys have an approximate gestation period of five to six months, and we'd been closely monitoring mum throughout her pregnancy - we knew she was due to give birth as her bump was huge!"
Threatened in their native South American homes of Bolivia, Peru and Brazil, the black-capped squirrel monkey's status in the wild is threatened from use in biomedical research and as pets, bait and food.
