Footage captured of rare interspecies infanticide by dolphins off coast of Wales

Four adult bottlenose dolphins killed a common dolphin calf in Cardigan Bay in an attack possibly caused by competition for resources

They were hoping for a nice day out on the bay. Instead, dolphin-watching tourists in Wales were confronted with the shocking and grisly sight of four adult bottlenose dolphins pursuing and killing a common dolphin calf.

The trip, in Cardigan Bay, was operated by Dolphin Spotting Boat Trips and the Sea Watch Foundation (SWF), a charity that monitors the dolphins in the bay to inform and advise on their conservation status and protection.
