Continuing the twice-weekly portrait of London Zoo and Whipsnade Park. The keepers have a hard day ahead of them, with 16 agile langur monkeys to catch, and hope to mate a male gorilla being brought down from Kent with two female gorillas in London. Meanwhile keeper Rachel Jones finds a cockroach for a jewel wasp to lay its eggs on, and vet Sue Thornton tackles the buckteeth that are giving a puffer fish eating problems.
The next episode is on Wednesday at 7.30pm.
