Talk about animal magnetism! The Zoological Society of San Diego is a not-for-profit organization that operates the 100-acre San Diego Zoo, which cares for more than 4,000 individual animals as well as a collection of some 6,500 species of plants. The Zoological Society also manages the 1,800-acre San Diego Zoo's Wild Animal Park and the center for Conservation and Research for Endangered Species. The zoo entertains all with its daily shows, in-park restaurants, guided tours, and special events. The society also supports conservation education and efforts, such as planned travel adventure-tours to exotic destinations such as Mexico or Africa. It was founded by Dr. Harry Wegeforth in 1916.
