| Summary: | Play is an important indicator of physical strength, cognitive functioning, and overall welfare for animals. Performed independently or cooperatively, play provides animals, including humans, opportunities to test and practice various physical abilities, social interactions, and object investigations. One area that is often overlooked in animal play is the presence and nature of games. Sometimes considered the social glue of human cultures, games enable participants to practice different moves, cooperatively follow a shared set of rules, and have ‘fun.’ Using archived footage collected from a stable beluga population in managed care for nearly 15 years, we examined spontaneous, untrained social interactions (i.e. games played) between two or more belugas. Social games encompassed repeated, role exchanges that involved a set of rules developed and shared between the interactants. The belugas engaged in seven different games: locomotor-based games with and without contact, triadic play involving inanimate objects and water, and socio-sexual play. Although most social games involved immature animals, some games did occur with adults. This catalog and description of the variety of games played by belugas will enable us to understand the role social behavior has in behavioral development and individual animal welfare.
