Crepidula convexa Say, 1822, Convex Slipper Shell
While the distribution map presented by Dr. Collin shows a break from about south Georgia to central Florida, Harry Lee, author of Marine Shells of Northeast Florida 2009, 6/9/2010 commented:
"Since your presentation indicated NE Florida is a "dead zone" [my quotes] for convex slipper shell group, let me assure you that we have found Crepidula convexa not uncommonly in these (our) waters."
Marlo: I have found Crepidula ustulatulina only as far north as Brevard County.
Pretty common in Maine where they likes being on rocks and in tidal pools.
