Florida has two species of Dosinea - elegans and discus.  The portrayal of
these two shells has been rather inconsistent among the several books
available to everyday collectors.  The biggest ambiguity appears to be
whether one or the other is an offshore species and the other limited to
bays and estuaries.  While my experience has both occurring in live
populations in bays and estuaries (at inlets), elegans dominates and discus
appears most often found as a beach shell along ocean shorelines.  I suspect
populations of both wax and wane and that when observations are made may
strongly influence impressions.  What has been your experience?
