Bipalium is a genus of large predatory land planarians. They are often loosely called "hammerhead worms" or "broadhead planarians" because of the distinctive shape of their head region. Land planarians are unique in that they possess a "creeping sole", a highly ciliated region on the ventral epidermis that helps them to creep over the substrate.[2] Native to Asia, several species are invasive to the United States,[3] Canada, and Europe.[4][5] Some studies have begun the investigation of the evolutionary ecology of these invasive planarians.[6]
