Image of Crepidula depressa Say 1822

Description:

The gastropod Eastern White Slippersnail, Crepidula depressa Say, 1882, is a common species found at University Beach, Corpus Christi Bay, Texas. This species has long been misidentified with Crepidula plana Say, 1822, which Rachel Colin (2002) restricted to Georgia and northward, therefore, C. plana does not occur in the Gulf of Mexico. Its shell can reach about 37 mm (1 1/2 in) in length and is quite depressed. It is found in virtually every large gastropod shell with a hermit crab, as well as on some bivalve shells on this beach. Read more about this species in Tunnell et al (2010)’s Encyclopedia of Texas Seashells, page 168, and in the Texas Seashells, A Field Guide (Tunnell, Barrera and Moretzsohn, 2014), on page 64.
