MARINE experts have caught on camera a pod of dolphins attacking a lone porpoise.
The Wildlife Trust Cardigan Bay Marine Wildlife Centre marine team were on a four-hour dolphin survey with Dolphin Survey Boat Trips when they witnessed the attack.
They were amazed to observe and document a group of seven bottlenose dolphins acting aggressively towards a young harbour porpoise, off the coast of Llangrannog.
Sarah Perry, Wildlife Trust Living Seas Science Officer said: “For decades we have known that bottlenose dolphins attack harbour porpoises, an act known as porpicide, a behaviour that has been documented around the world however, the reasons for these attacks remains poorly understood. “Various theories have been proposed including prey competition, object-orientated play, practicing infanticide and heightened aggression in male bottlenose dolphins.
“Interestingly this isn’t the first time we have observed this behaviour in the Cardigan Bay bottlenose dolphins; in 2014 we observed this behaviour first-hand on four occasions”.
During the latest encounter the Cardigan Bay Marine team photographed the dolphins involved, observed and documented their behaviour.
