The Ribbed Cantharus


The Ribbed Cantharus, Hesperisternia multangula (Philippi, 1848), is a very variable species ranging in color from brown-marked to orange shells. The Ribbed Cantharus closely resembles two species of oyster drills, the Mauve-mouth Drill and the Gulf Oyster Drill, and for this reason is also known as the False Drill. The Ribbed Cantharus has eye-catching egg cases that resemble miniature stars.
