“…Both species are also commonly transported as adults and juveniles on the shells of horseshoe crabs and oysters (Blanchard, 1997(Blanchard, , 2009Bohn, Richardson, & Jenkins, 2015;Coe, 1936;Orton, 1912;Thieltges, Strasser, & Reise, 2006;Winkley, 1888). Neither species apparently serves as an intermediate host for parasitic flatworms (Pechenik, Fried, & Bolstridge, 2012;Pechenik, Fried, & Simpkins, 2001).…”

The marine gastropod Crepidula plana has an extensive latitudinal range along the eastern coast of the United States. It is usually found living within gastropod shells occupied by hermit crabs, although individuals can sometimes also be found living on rocks and on the exposed surfaces of shells. Our study sought to determine the extent to which residing inside periwinkle (Littorina littorea) shells occupied by the hermit crab Pagurus longicarpus at a study site in coastal Massachusetts compromises the fecundity of C. plana, through size limitation. The egg masses of symbiotic and free‐living females of C. plana included comparable numbers of egg capsules and embryos per female despite the smaller sizes of the symbionts; symbiotic females compensated for their smaller size by producing significantly more embryos per milligram of female body tissue than their free‐living counterparts. These data raise interesting questions about why—unlike its congener C. fornicata—C. plana has not yet become a successful invasive species.

“…As with all other calyptraeids, adults of C. fornicata are sedentary, so that different degrees of adult dispersal ability (Brousseau & McSweeney 2016) should also not be related to ecological invasion success. Some species become successful invasives by leaving behind their parasites (Torchin et al 2003); however, C. fornicata, C. plana, and C. convexa do not seem to serve as first host species for trematodes (Pechenik et al 2001(Pechenik et al , 2012, although one related South American species (Crepipatella dilatata) does (Gilardoni et al 2012). Moreover, many individuals of C. fornicata found in French waters are infected by the French shell borer Cliona celata, although the infestation does not appear to be harmful (Le Cam & Viard 2011).…”

The calyptraeid gastropod Crepidula fornicata is native to the eastern coast of the United States but has now become an extremely successful invader along much of the European coastline. As the northern limit of its spread is thought to be determined by an inability of adults to tolerate prolonged exposure to low winter temperatures, this study sought to compare the fecundity of females collected from two sites along the Norwegian coastline with that of females collected from Rhode Island, USA. Few other studies have compared the fecundities of marine invertebrates from invasive populations with those found in native populations. For both populations studied, fecundities increased with increasing shell length. However, contrary to expectations, size‐related fecundities were significantly higher for Norwegian females than for Rhode Island females, with Norwegian females producing larger egg capsules and a greater number of embryos per capsule, but not a greater number of egg capsules per brood. Current evidence suggests that at the northern extreme of its invaded range, the fecundity of C. fornicata is increased rather than compromised.
