The Conjugal Behavior of the Introduced European Giant Garden Slug, Limax Maximus L., as Observed on South Bass Island, Lake Erie

Abstract

A pair of giant garden slugs, though permaphrodies hermaphrodites, behave as if one were male and one were female during the period just preceding, during, and after mating. A description of this behavior, with photographs, is presented, and the possibility of protandrism is suggested.
