Dewald le Grange took pictures of horse mussels on Muizenberg beach on Sunday June 14. Mr Le Grange did some research and found that the horse mussels are a rare sight. According to the Scottish Natural Heritage site, horse mussels are similar to blue mussels and the species occurs all around the British Isles but is more common in the north. The most extensive bed, or reef, is off the north-east coast, in depths of 5m to 70m. Horse mussels grow up to 20cm in length – and usually live below the low watermark. Horse mussel beds are also protected in 12 locations around Scotland.
