We discovered this beauty on a sand/shingle beach at Costa Sancti Petri, nr Cadiz, in Andalucia in April 2012. I thought it was a huge shell but on trying to lift it, discovered the shell to be occupied. It weighed about 1 kilo and was 6 to 8 inches in diameter. I'm not sure if the rough texture of the snail itself was due to shingle adhering or whether the 'skin' was rough. Did not want to touch it! I have over the past few years, seen fragments of what appeared to be very large shells at another nearby sandy beach (El Palmar) but this is the first time I have seen a complete shell (plus inhabitant). Can anyone identify it please?
