Among them, however, is a group of “giant” species, all of which have a “hammerhead”: the bipaliines, belonging to the genera Bipalium and Diversibipalium. These flatworms, which move from continent to continent as plants and soil are transported, are generally of modest size, about 5 cm long – they can be held in the hand, although it is a bad idea to touch them. In France, we have seen recently the arrival and proliferation of the “devil bug”, the Asian hornet and the Siberian chipmunk, as well as land flatworms such as Platydemus manokwari (from New Guinea) and Obama nungara (from South America). One of the consequences of globalisation and increased international trade in goods is the introduction of invasive species.
