Prey-transfer in the marine tucuxi dolphin, Sotalia fluviatilis, on the Brazilian coast

Marine Biodiversity Records, 2008
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 ...

Population Structure of Riverine and Coastal Dolphins Sotalia fluviatilis and Sotalia guianensis: Patterns of Nuclear and Mitochondrial Diversity and Implications for Conservation

Journal of Heredity, 2018
Coastal and freshwater cetaceans are particularly vulnerable due to their proximity to human activity, localized distributions, and small home ranges. These species include Sotalia guianensis, found in the Atlantic and Caribbean coastal areas of central and South America, and Sotalia fluviatilis, distributed in the Amazon River and tributaries.
