Miscellaneous records held on the Cofnod database. They were once all considered to be in the same genus (Littorina), but one has now been shifted to the genus Melarhaphe. Out of the water, they can stay moist by closing up their shell with a trapdoor-like structure called an operculum.  This ecotype shows a smaller and thinner shell with a wider shell aperture to allocate a relatively larger muscular foot providing a higher ability to avoid the dislodgment caused by the heavy wave action. There are two genera in the plant family â Catharanthus or Madagascar periwinkles, and Vinca or European periwinklesâas well as three genera in the animal family â Littorina littorea or the common periwinkle, the Nodilittorina unifasciata or blue periwinkle, and Littorina saxatilis or rough periwinkle.
