Giant whelk- mono monday

I collected this   giant whelk in the Caribbean some time ago hoping that one-day I could use it in some photographic project.
 
   
Well today it has its three seconds of fame- as my contribution to mono Monday Symmetry, hosted by chantler63


Whoops !  just realised it should be pattern rather than symmetry....oh well.
   
It does ,however, look much better in colour.
