Ever wondered what a manatee eats? Or how zookeepers care for animals' teeth? On July 23, visitors will get the chance to have both of these questions answered.

As part of the Singapore Science Festival, the zoo is giving visitors a behind-the-scenes look at their operations. The tour will include a visit to the zoo's central kitchen, as well as the Wildlife Research and Healthcare Centre where visitors will learn about animal dentistry and medical care.

Since 2011, the zoo has worked with the Singapore Science Centre to open these tours to the public once a year, during the Festival.

There will one hour-sessions at 10am and 2pm. Tour groups will be between five and 30 people. Members of the public need to pre-register for the tour, which costs $18 for children and $25 for those 13 and above. To register, e-mail haniman.b@wrs.com.sg
