Bolivian squirrel monkeys play with a toy soccer ball as photographers snap away at the London Zoo.
The zoo has a total of 22 squirrel monkeys, with five babies having been born in 2011 so far.
Male monkey Bounty has fathered eleven baby monkeys in the last three years since his arrival, enough to make up a football team. His latest offspring named Rolo was number 11 and arrived last month.
