This behaviour, previously documented in domestic animals like cats, marks the first time such food-sharing has been observed and studied in wild predators.
Researchers analysed 34 instances over two decades across various global locations, where orcas approached humans and presented them with prey.
The study indicates that orcas often waited for a human reaction and, in some cases, re-offered the food if initially refused, showing persistence.
Experts suggest this food-sharing could be a way for these intelligent and social marine mammals to build connections, practice learned behaviors, or explore human interaction.
