Murex trapa or altispira - mark - 08-17-2014 Hello, Can you hep me, please? they are 6,5-10 cm. Thanks, Mark RE: Murex trapa or altispira - paul monfils - 08-18-2014 These are Murex trapa.  It has relatively short, thick, slightly curved spines, and heavy sculpture on the body whorl.  Murex altispira has longer, more slender and more curved spines, and reduced sculpture on the body whorl.  There are other differences as well, but these are sufficient to separate the two.
