Pregnant woolly monkey Piquita approaches her due date at Dorset's Monkey World, while capuchin Sean from Chile demonstrates his grooming skills and ruffed lemur Blue's life hangs in the balance.

The female capuchins fight, Tia needs surgery, and orangutan Amy enters the late stages of pregnancy. Elsewhere, there is a new addition to the play area in the chimp nursery, and Alison visits Paulo - the baby woolly monkey she has successfully hand-reared - for the final time.
