A love of lemurs and a passion for presenting are all that are required to assist in the walk-through lemur section of the zoo's brand new monkey enclosure that opens in June.
As a charity, the zoo relies on its volunteers to provide many activities to visitors.
They help with running the children's activity centre, presenting animal encounters, assisting with special events and - from 23 June - helping out in the monkey jungle, where visitors will have open access to ring-tailed and red-ruffed lemurs.
"I've been a volunteer at the zoo every Wednesday for 10 years now," says Doris Woodruff.
"It's a fantastic environment and I've had the opportunity to be involved in all sorts of activities I would never have dreamt of.
"The fascination on a child's face when you are explaining about live animals that they can interact with really is worth more than money to me. I can't recommend it highly enough to anybody that has time to spare."
"We really cherish our volunteers," says Ann Lovell, the zoo's volunteers manager.
"Helping children to understand the natural world is really important for the future and that is what our volunteers do. Without them, we would be unable to engage with as many people as we do."
