The Cornish Seal Sanctuary is expressing frustration after a hollow flying ring was discovered on a quiet beach near Gweek.   The ring was spotted by Seal Research Trust volunteers, Elizabeth Hall and her daughter Flo, during a walk with their dog late last year. "Seals are naturally inquisitive and often play with objects they find along the shore.   Unfortunately, hollow flying rings can become trapped over their heads, causing slow and painful injuries, sometimes even resulting in death" said Grace Jones, Conservation Officer at the Cornish Seal Sanctuary. In July last year, Cornwall Council voted unanimously to introduce a voluntary ban on hollow flying rings.   The initiative is not about preventing people from enjoying the beach; it´s a simple measure that can have a huge impact on marine wildlife.   Solid flying discs offer the same fun but do not carry the same deadly risk for seals, dolphins, and other coastal animals.
