Rare dolphin shelling captured in Australia suggests mother-to-calf teaching

Researchers documented an extremely rare ‘shelling’ behavior in bottlenose dolphins off Queensland, Australia, where shells are used as tools to trap fish. The observation included both an adult female and her calf, suggesting the calf learned the behavior from its mother and providing potential evidence of maternal social transmission. The finding also underscores the importance of traditional wildlife photography for documenting new scientific insights.
