| Abstract |
In April 2007 the first two authors investigated the rocky outcrops on the beach of Audresselles, northwest France, for the presence of marine molluscs. Special attention was paid to Nucella lapillus (Linnaeus, 1758), also known as the Atlantic dog-whelk. A study of the collected material revealed that part of the specimens possessed a strongly reduced operculum, some animals were even completely devoid of an operculum. The aim of this article is to provide some information concerning the variability of the operculum in this population of Nucella lapillus. |
