vacation shelling questions for Gran Canaria

[pvdb]

I am going to Gran Canaria - South - Maspalomas - end of december - family vacation , no diving , no shelling ( that means : no shelling planned ... ).Is there however something interesting to "shell" ? The island is small , busses and taxis cheap . Hints are wellcome : local collectors , good places , prohibited or protected species . Good hints can be rewarded as far as possible . BBG from PVDB .
