Zoos, aquariums, and other captive animal facilities offer promising opportunities to advance the science and practice of behavior analysis. Zoos and aquariums are necessarily concerned with the health and well-being of their charges and are held to a high standard by their supporters (visitors, members, and donors), organized critics, and the media. Zoos and aquariums offer unique venues for teaching and research and a locus for expanding the footprint of behavior analysis. In North America, Europe, and the UK, formal agreements between zoos, aquariums, and university graduate departments have been operating successfully for decades. To expand on this model, it will be necessary to help zoo and aquarium managers throughout the world to recognize the value of behavior analysis in the delivery of essential animal health and welfare services. Academic institutions, administrators, and invested faculty should consider the utility of training students to meet the growing needs of applied behavior analysis in zoos and aquariums and other animal facilities such as primate research centers, sanctuaries, and rescue centers.Keywords Animal training .

ZoosPsychologists trained in behavior analysis have a long history of conducting basic and applied research with exotic wildlife in zoos, aquariums, and specialized marine parks. At one time, operant conditioning techniques were routinely deployed to train cetaceans (dolphins and porpoises) in studies of discrimination, sensory perception, and echolocation (Kellogg and Rice 1966;Pryor 1981;Tavolga 1966). Many studies of cetaceans and pinnipeds (seals, sea lions, walrus) have been published in psychology journals, including the
