Bipalium vagum, the wandering hammerhead worm, is a land planarian in the subfamily Bipaliinae. It has been accidentally introduced in the United States, Bermuda and various islands in the Caribbean [1] [2] [3] and was recorded for the first time in Europe, in Italy, in 2021. [4]

Description

Bipalium vagum is a relatively small species of Bipalium, measuring about 25 mm (0.98 in) in length. The head varies from entirely black to dark brown with two black patches separated by a lighter ground color. The neck has a black collar interrupted only at the creeping sole. The dorsal color of the body is light brown and a broad black stripe runs longitudinally from the black collar to the posterior end. Laterally, there are two diffuse dark brown stripes. [1] [3]

Feeding Habits

Differently from other invasive species of Bipalium, which feed on earthworms, B. vagum seems to feed exclusively on gastropods. As it seems to be spreading throughout the Caribbean and southern United States, there is certain concern on its possible impacts on the native gastropod fauna. [1] [2]

<i>Bipalium</i> Genus of flatworms

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. Native to Asia, several species are invasive to the United States, Canada, and Europe. Some studies have begun the investigation of the evolutionary ecology of these invasive planarians.
