Seal filmed feeding on porpoise 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 Pembrokeshire coast.

The footage, taken by a local wildlife watcher, 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.
