Zoo educators teach visitors about the animals living at the zoo/aquarium as well as other species and habitats. They provide information about management of zoos, its collection of animals, and wildlife conservation. Zoo educators can be involved in both formal and informal learning opportunities ranging from production of information signs at enclosures to delivering classroom sessions linked to school or university curricula. Depending on the size of the organisation the education team may be a single person or a large team. Consequently the optional skills required are very broad and will vary from organisation to organisation. Zoo educators also promote conservation efforts. This can involve work within the zoo but also in the field as part of any zoo outreach project(s).
