Crepidula depressa Say, 1822
Location: SMR Phase 10, Sarasota County, Florida USA.
Status: Extant
Notes: Flat to concave due to its preference for attachment on the inside of the aperture of dead gastropods. Fossil species have traditionally been named Crepidula plana also a species still living today. Molecular studies have shown that although nearly identical in appearance C. depressa is a different species restricted to the warmer waters of Florida while C. plana extends along the Northern Atlantic as far south as the Carolinas and Georgia.
