The Lake Pedder planarian (Romankenkius pedderensis) is a species of invertebrate in the family Dugesiidae. [3]
The species is endemic to the Lake Pedder area in Tasmania, Australia. This species has been listed as extinct by the IUCN Red List of Threatened Species since 1986, although their last conservation assessment was dated 1996. [2] Live specimens of this species were collected in 2006 [4] [ failed verification ] and the ongoing existence of the species was again confirmed in 2012. [1]
Southwest National Park is an Australian national park located in the south-west of Tasmania, bounded by the Franklin-Gordon Wild Rivers National Park to the north and the Hartz Mountains National Park to the east. It is a part of a chain of national parks and state reserves that make up the Tasmanian Wilderness World Heritage Area. Covering an area of 6,183 km2 (2,387 sq mi), it is Tasmania's largest national park.
Lake Pedder, once a glacial outwash lake, is a man-made impoundment and diversion lake located in the southwest of Tasmania, Australia. In addition to its natural catchment from the Frankland Range, the lake is formed by the 1972 damming of the Serpentine and Huon rivers by the Hydro Electric Commission of Tasmania for the purposes of hydroelectric power generation.
The Pedder galaxias is an Australian freshwater fish. It is considered to be extinct in the wild since 2005 by the EPBC Act, and was originally found only in Lake Pedder in Tasmania.
Dugesia is a genus of dugesiid triclads that contains some common representatives of the class Turbellaria. These common flatworms are found in freshwater habitats of Africa, Eurasia, and Australia. Dugesia is best known to non-specialists because of its regeneration capacities.
Romankenkius is a genus of freshwater planarian in the family Dugesiidae.
The Lake Pedder earthworm is an extinct earthworm species in the family Megascolecidae. Its genus Hypolimnus is monotypic.
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.
Dugesiidae is a family of freshwater planarians distributed worldwide. The type genus is Dugesia Girard, 1850.
Girardia is a genus of freshwater planarians belonging to the family Dugesiidae.
Dugesia notogaea is a species of dugesiid triclad that inhabits freshwater bodies of north Queensland, Australia.
Microplana is a genus of land planarians found in Europe and Africa.
Microplaninae is a subfamily of land planarians.
Neppia is a genus of dugesiid triclad that is found in South America, Subantarctic region, Africa, Tasmania and New Zealand.
Cavernicola is a suborder of planarians found mostly in freshwater habitats of caves, although some species occur on the surface.
Geoplaninae is a subfamily of land planarians endemic to the Neotropical region. Members of this family are sometimes referred to as the Neotropical land planarians. However, one species, Obama nungara has been introduced in Europe.
The reproductive system of planarians is broadly similar among different families, although the associated structures can vary in complexity.
Marionfyfea is a genus of land planarians from Antarctic Islands off New Zealand. However, a species has been described from specimens found in Europe, probably introduced.
Marionfyfea adventor is a species of land planarian described in 2016 from specimens found in the United Kingdom, the Netherlands and France. However, since the species belongs to the genus Marionfyfea, of which the species are known only from subantarctic islands off New Zealand, it is probably an introduced species in Europe.
Sarcoplanini is a tribe of land planarians in the subfamily Geoplaninae.
