The first record of prey-transfer behaviour between adult and calf animals in Sotalia fluviatilis is recorded. Five clear episodes of prey-transfer from adult animals to calves were observed, occurring in north-eastern Brazil at Pipa's Beach. These results suggest that food-sharing is a naturally occurring behaviour in the marine tucuxi dolphin, and that it may act as both a food supply and as an opportunity to obtain information about the food that is eaten by other group members.
