Skomer seal plays with Pembrokeshire survey marker buoy

Playful seals have been filmed playing with monitoring equipment in the sea off the coast of Pembrokeshire.

Natural Resources Wales (NRW) staff working on a range of underwater monitoring projects on the Skomer Marine Nature Reserve have taken video footage of one seal playing with a surface marker buoy.

Another seal is said to have taken great interest in a diver's flipper.

At this time of year NRW carries out a survey of Atlantic grey seal pups of which more than 300 are born on Skomer Island.
