Bipalium vagum Jones & Sterrer, 2005 | |
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]
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]
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]
The New Zealand flatworm is a large land flatworm native to New Zealand. It can vary from 5 mm in length when hatched to approximately 17 centimetres (6.7 in) in mature adults.
Geoplanidae is a family of flatworms known commonly as land planarians or land 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.
Caenoplana coerulea, known as the blue planarian or blue garden flatworm is a species of land planarian.
Platydemus manokwari, also known as the New Guinea flatworm, is a species of large predatory land flatworm.
Bipalium kewense, also known as the shovel-headed garden worm, is a species of large predatory land planarian with a cosmopolitan distribution. It is sometimes referred to as a "hammerhead flatworm" due to its half-moon-shaped head, but this name is also used to refer to other species in the subfamily Bipaliinae.
Bipalium adventitium, the wandering broadhead planarian, is a land planarian in the subfamily Bipaliinae. It has been accidentally introduced in the United States, where it is considered invasive.
Bipaliinae is a subfamily of land planarians found mainly in Madagascar, the Indian subcontinent and Southeast Asia, although some species have been introduced worldwide.
Diversibipalium multilineatum is a species of large predatory land flatworm.
Endeavouria is a monotypic genus of land planarians from the Pacific region. It contains a single species, Endeavouria septemlineata.
Amaga is a genus of land planarians from South America.
Obama nungara is a species of land planarian in the family Geoplanidae. It is native to South America, but has been introduced in Europe.
Kontikia is a genus of land planarians native from islands in the Indo-Pacific region, but several species have been introduced elsewhere.
Novibipalium is a genus of land planarians of the subfamily Bipaliinae.
Humbertium is a genus of land planarians of the subfamily Bipaliinae.
Diversibipalium is a genus of land planarians of the subfamily Bipaliinae. It was erected to include species lacking sufficient morphological information to allow them to be classified in the appropriate genus.
Gigantea gouvernoni is a species of land planarian belonging to the subfamily Geoplaninae. It is known from specimens collected from the grounds of Government House, Bermuda.
