New Zealand Flatworm
The New Zealand flatworm (''Arthurdendyus triangulatus'') is a large land flatworm native to New Zealand. It can vary from 5 mm in length when hatched to approximately in mature adults. The New Zealand flatworm is considered an invasive species in parts of Europe. This species is included since 2019 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union. Description The ventral surface of the flatworm is a pale buff colour while the dorsal surface is dark brown. Young flatworms vary in colour from white to pale orange and develop their adult colouration as they grow. During the day, flatworms can be found resting on the surface of soil underneath objects in close contact with the ground. They may also be found beneath the soil surface hunting for earthworms. Reproduction involves the pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australoplana
''Australoplana'' also known as Australian flatworm is a genus of land planarians from Australia and New Zealand. Description The genus ''Australoplana'' is characterized by having an elongated, strap-like body that is broadly convex dorsally and flat ventrally. The creeping sole occupies less than 25% of the body with. The eyes are absent or minute and arranged along the body margins in a single row from the anterior to the posterior end. The parenchymal longitudinal musculature is very weak or absent. The copulatory apparatus has an intra-antral penis papilla in some species and the ovovitelline ducts enter the female atrium ventrally. Invasive species ''Australoplana sanguinea'' is an invasive alien species in England and Wales where it predates on earthworms. Etymology The name ''Australoplana'' comes from Latin ''australis'', southern + ''plana'', flat. Species The genus ''Australoplana'' includes the following species: *'' Australoplana alba'' *''Australoplana mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belfast
Belfast ( , ; from ga, Béal Feirste , meaning 'mouth of the sand-bank ford') is the capital and largest city of Northern Ireland, standing on the banks of the River Lagan on the east coast. It is the 12th-largest city in the United Kingdom and the second-largest in Ireland. It had a population of 345,418 . By the early 19th century, Belfast was a major port. It played an important role in the Industrial Revolution in Ireland, briefly becoming the biggest linen-producer in the world, earning it the nickname "Linenopolis". By the time it was granted city status in 1888, it was a major centre of Irish linen production, tobacco-processing and rope-making. Shipbuilding was also a key industry; the Harland and Wolff shipyard, which built the , was the world's largest shipyard. Industrialisation, and the resulting inward migration, made Belfast one of Ireland's biggest cities. Following the partition of Ireland in 1921, Belfast became the seat of government for Northern Ireland. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geoplanidae
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms. These flatworms are mainly predators of other invertebrates, which they hunt, attack and capture using physical force and the adhesive and digestive properties of their mucus. They lack water-retaining mechanisms and are therefore very sensitive to humidity variations of their environment. Because of their strict ecological requirements, some species have been proposed as indicators of the conservation state of their habitats. They are generally animals with low vagility (dispersal ability) and with very specific habitat requirements, so they can be also used to accurately determine the distribution of biogeographic realms. Today the fauna of these animals is being studied to select conservation priorities in the Atlantic rainforest in Brazil. At the other extreme, one species in this family, '' Platydemus manokwari'' has become an invasive species in both disturbed and wild habitats in the ...

Platydemus Manokwari
''Platydemus manokwari'', also known as the New Guinea flatworm, is a species of large predatory land flatworm. Native to New Guinea, it has been accidentally introduced to the soil of many countries, including the United States. It was also deliberately introduced into two Pacific islands in an attempt to control an invasion of the Giant East African Snail. It eats a variety of invertebrates including land snails, and has had a significant negative impact on the rare endemic land snail fauna of some Pacific islands. It has become established in a wide variety of habitats. General ecology Description It is relatively large, about in length and about wide. Its body, however, is quite flat, being less than in thickness. Both ends of the animal are pointed, but the head end is more pointed than the tail end.''Pla ...

Platydemus
''Platydemus'' is a genus of large predatory land planarians in the tribe Rhynchodemini. Description Species of the genus ''Platydemus'' are characterized by a massive, slightly convex body with a broad creeping sole and very large eyes. The copulatory apparatus has a large chamber with folded epithelium in the male atrium, usually with a small penis.

Bipalium
''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. Several species are considered invasive to the United States, Canada, and to Europe. Some studies have begun the investigation of the evolutionary ecology of these invasive planarians. Etymology The name ''Bipalium'' comes from Latin ''bi-'', "two" + ''pala'', "shovel" or "spade", because species in this genus resemble a pickaxe. Description The genus ''Bipalium'' was initially defined by Stimpson to include land planarians with the head broadened, forming a head plate. Later, in 1899, Ludwig von Graff divided it into three genera according to the shape of the head: #''Bipalium'': with a well-developed head plate, much broad ...

Planarian
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 triclads are characterized by triply branched intestine and anteriorly situated ovaries, next to the brain. Today the order Tricladida is split into three suborders, according to their phylogenetic relationships: Maricola, Cavernicola and Continenticola. Formerly, the Tricladida was split according to habitats: Maricola, which is marine; Paludicola which inhabits freshwater; and Terricola, which is land-dwelling. Planaria exhibit an extraordinary ability to regenerate lost body parts. For example, a planarian split leng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faroe Islands
The Faroe Islands ( ), or simply the Faroes ( fo, Føroyar ; da, Færøerne ), are a North Atlantic island group and an autonomous territory of the Kingdom of Denmark. They are located north-northwest of Scotland, and about halfway between Norway ( away) and Iceland ( away). The islands form part of the Kingdom of Denmark, along with mainland Denmark and Greenland. The islands have a total area of about with a population of 54,000 as of June 2022. The terrain is rugged, and the subpolar oceanic climate (Cfc) is windy, wet, cloudy, and cool. Temperatures for such a northerly climate are moderated by the Gulf Stream, averaging above freezing throughout the year, and hovering around in summer and 5 °C (41 °F) in winter. The northerly latitude also results in perpetual civil twilight during summer nights and very short winter days. Between 1035 and 1814, the Faroe Islands were part of the Kingdom of Norway, which was in a personal union with Denmark ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Dendy
Arthur Dendy (20 January 1865, in Manchester – 24 March 1925, in London) was an English zoologist known for his work on marine sponges and the terrestrial invertebrates of Victoria, Australia, notably including the "living fossil" '' Peripatus''. He was in turn professor of zoology in New Zealand, in South Africa and finally at King's College London. He was a Fellow of the Royal Society. Family life Dendy's parents were John Dendy, a silk fabric maker of Manchester, and Sarah Beard, daughter of John Relly Beard. His sisters included Mary Dendy and Helen Bosanquet.
