Beluga whales in captivity currently show signs of mental distress through stereotypical behaviors such as repetitive pacing. It is currently well established that the social structure of beluga whale pods can alter beluga whale social behavior. This study aims to determine how differing social structures of beluga whale pods correlate to the frequency of repetitive pacing. In this context repetitive pacing is when a beluga whale paces three or more laps in the same pattern and direction. To

... t the hypothesis that beluga whales in larger more diverse pods will repetitively pace less than beluga whales in smaller more uniform pods, a behavioral observation was conducted at Seaworld Orlando and Georgia Aquarium. Over 20 observation periods, the amount of times repetitively paced, amount of laps while repetitively pacing, and the amount of laps repetitively paced per hour were all noted. The results supported the hypothesis, correlating the more diverse pod to less frequent repetitive pacing. These results suggest that pod social structure can play a role in captive beluga whales' mental wellbeing. On this basis, during future transfers, more diverse pods should be put together to try to limit the amount of repetitive pacing and improve the mental wellbeing of captive beluga whales.
