Overview
There are small areas in the North Sea where there are ancient stones, completely covered with colourful sea creatures. Meet these mini reefs. Tube worms build their own natural reefs. They form an expansive carpet where young animals can flourish. Reefs of shellfish also support abundant communities. The number of oil and gas rigs and wind turbines in the North Sea is growing. These structures can also transform into reefs. Will the Atlantic cod return to the southern North Sea as a result?
