Bipalium nobile is a land planarian of the subfamily Bipaliinae found in Japan.
Bipalium nobile is a very long planarian, reaching up to 1 m (3.3 ft) in length. As in other species of Bipalium , the head is expanded, being fan-shaped in live animals. The dorsal color is pale yellowish brown with five blackish brown longitudinal stripes. The head is usually darker than the rest of the body. [1]
Little is known about the ecology of B. nobile. The species started to be found in Tokyo by the end of the 1970s. As it was not reported in previous surveys in the area, it is assumed to be introduced from elsewhere. [1]
Studies on regeneration have shown that B. nobile has a great regenerative ability similar to that of freshwater planarians. [2]
A planarian is one of the many flatworms of the traditional class Turbellaria. It usually describes free-living flatworms of the order Tricladida (triclads), although this common name is also used for a wide number of free-living platyhelminthes. Planaria are common to many parts of the world, living in both saltwater and freshwater ponds and rivers. Some species are terrestrial and are found under logs, in or on the soil, and on plants in humid areas.
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.
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.
Bipalium pennsylvanicum, the three-lined land planarian, is a species of land planarian in the subfamily Bipaliinae. They are native to Asia, but found mostly in Pennsylvania and the surrounding areas. They can reach a length of 5.1 inches or more, with a diet consisting mostly of earthworms. They reproduce sexually by creating a cocoon in the spring, but unlike related planarians, they cannot reproduce through binary fission. It is not recommended to touch these flatworms without gloves, because their mucous contains a toxin that is used for digesting prey and can cause skin irritation for some people.
Diversibipalium multilineatum is a species of large predatory land flatworm.
Robert Edward Ogren was an American zoologist.
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.
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 and was recorded for the first time in Europe, in Italy, in 2021.
Neoblasts (ˈniːəʊˌblæst) are non-differentiated cells found in flatworms called planarians. Neoblasts make up about 30 percent of all cells in planaria. Neoblasts give planarians an extraordinary ability to regenerate lost body parts. A planarian split lengthwise or crosswise will regenerate into two separate individuals.
Bipalium fuscatum is a species of land planarian first described by William Stimpson in 1857. It has been found in Japan, Indonesia, and in parts of continental South Asia and East Asia such as China, India and Korea. This hammerhead flatworm may be able to survive for days in a human lung as a pseudoparasite.
Vermiviatum covidum is a species of predatory land flatworm, found in France and Italy. The Holotype specimen is MNHN JL351B.
Bipalium adensameri is a species of predatory land planarian. It has been found on Java in Indonesia as well as in Vietnam.
Bipalium javanum, the Javan broadhead planarian, is a species of land planarian belonging to the subfamily Bipaliinae. It is endemic to Indonesia.
