New grey seal behaviour filmed off Pembrokeshire coast

A seal feeding on a harbour porpoise it had just killed has been caught on camera for the first time off the coast of Pembrokeshire.

The footage, taken by a local wildlife watching operator, showed an adult male grey seal biting and eating its prey.

Researchers believe seals could be taking on larger prey due to increasing competition for food.

Natural Resources Wales said the video is thought to be the first of its kind in the world.

Seals normally feed on fish but the new footage shows they will also take much larger prey
