I have found this species almost everywhere I have been in Florida, on both coasts as you described. I have also found it as far north as the Charleston area in South Carolina.

I've found live ones at low tide on Shackelford Banks in North Carolina.

I agree that both species are uncommon to rare on treasure coast. I usually find at least one or two over three weeks stay in fla for a few years now on beaches. To me both species occurs at the same frequency. And too add the fact that they can on first glance resembles broken sharks eye spirals which both whole and broken shells occurs at a far higher frequency on beaches than baby's ears. Then add to the problem unless looked at spiral heights iron stained sinum perspectivum do exists.
