Uramphisopus pearsoni is a species of isopod crustaceans in the family Phreatoicidae. It is only found in Brandum Bay basin in the north of Great Lake, Tasmania. [3]
The shortnose cisco is a North American freshwater whitefish in the salmon family Salmonidae. One of the members of the broader Coregonus artedi species complex of ciscoes, it is native to the Great Lakes of Canada and the United States. Its population has been declining and it has disappeared from some of its earlier haunts. The last reported population was restricted to Georgian Bay off Lake Huron in Canada. It is thought that declines in the population of this fish may be linked with the arrival of the sea lamprey, in the Great Lakes. The International Union for Conservation of Nature has rated the conservation status of this fish as "critically endangered", and possibly extinct.
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.
Asellus aquaticus is a freshwater crustacean resembling a woodlouse. It is known by various common names including pond slater, water louse, aquatic sowbug, water hoglouse and cress bug.
Anaspididae is a family of freshwater crustacean that is endemic to Tasmania, Australia. The family contains 3 genera and 5 species. This group of crustaceans are considered living fossils. They are commonly and collectively known as the Tasmanian anaspid crustaceans. Anaspidids have stalked eyes, long antennae and antennules, and a slender body with no carapace. The two species of Allanaspides and the single species of Paranaspides are all listed as vulnerable on the IUCN Red List.
The shortjaw cisco is a North-American freshwater whitefish in the salmon family. Adult fish range to about 30 cm (12 in) in length and are silver, tinged with green above and paler below. One of the members of the broader Coregonus artedi complex of ciscoes, it is distributed widely in the deeper lakes of Canada, but populations in the Great Lakes have been declining and it is no longer present in Lakes Michigan, Huron, and Erie. It feeds mainly on crustaceans and insect larvae and spawns in the autumn on the lake bed. It is part of the important cisco (chub) fishery in the Great Lakes. The International Union for Conservation of Nature has rated its conservation status as "vulnerable". Shortjaw cisco have however evolved from the cisco Coregonus artedi independently in different lakes and different parts of the range, and conservation assessments therefore should be made on a lake-wise rather than range-wide basis.
Pearson's long-clawed shrew is a species of mammal in the family Soricidae. It is the only species within the genus Solisorex. It is endemic to Sri Lanka. Its natural habitats are subtropical or tropical dry forests and lowland grasslands. It is threatened by habitat loss. It is named after Joseph Pearson FRSE, Director of the Columbo Museum 1910-1933 who found it on 1 January 1924.
Allocrangonyx is a genus of troglobitic amphipod crustaceans from the South Central United States. The two species are both listed as vulnerable on the IUCN Red List. The animals are blind and unpigmented. During the male's development, the outer ramus of the third uropod differentiates into secondary segments and grows to a length greater than the animal's body length.
Branchinecta is a genus of crustacean in family Branchinectidae. It includes around 50 species, found on all continents except Australia. Branchinecta gigas, the giant fairy shrimp, is the largest species in the order, with a length of up to 10 centimetres (4 in), and Branchinecta brushi lives at the highest altitude of any crustacean, at 5,930 metres (19,460 ft), a record it shares with the copepod Boeckella palustris. A new genus, Archaebranchinecta was established in 2011 for two species previously placed in Branchinecta.
The vernal pool fairy shrimp, Branchinecta lynchi, is a species of freshwater crustacean in the family Branchinectidae. It is endemic to the U.S. states of Oregon and California, living in vernal pools as well as non-vernal pool habitat. They range in size from 0.43 to 0.98 inches long. Vernal pool fairy shrimp are listed as a vulnerable species on the IUCN Red List, and has been listed as Federally Threatened species since 1994.
Gammarus hyalelloides is a species of amphipod crustacean in the family Gammaridae. It is endemic to four springs in Jeff Davis County and Reeves County, Texas, and is listed as a vulnerable species on the IUCN Red List.
Lirceus is a genus of isopod crustaceans in the family Asellidae that live in southern Canada and the eastern United States as far west as the Great Plains. Of the 15 species in the genus, two are listed as either endangered (EN) or vulnerable (VU) on the IUCN Red List.
Mexistenasellus is a genus of isopod crustaceans in the family Stenasellidae.
Newnhamia is a genus of ostracods. It contains five species, four of which are endemic to Australia and surrounding islands, while a fifth was described in 2003 from Kerala, India. Two species from South America, described as species of Newnhamia, do not appear to be closely related to the remaining species, and probably belong in a different genus. N. fuscata and N. insolita are both listed as vulnerable species on the IUCN Red List.
Onchotelson is a genus of isopod crustaceans in the family Phreatoicidae, which is endemic to Tasmania. It contains two species, both of which are listed as vulnerable on the IUCN Red List:
Sphaerolana is a genus of isopod crustaceans in the family Cirolanidae, all of which are endemic to Mexico.
Stygobromus is a genus of amphipod crustaceans that live in subterranean habitats. The majority of the listed species are endemic to North America, a smaller number of species are also known from Eurasia. Most of the North American species live in areas which were not covered by the Laurentide Ice Sheet, although a few species seem to have survived under the ice. A number of species are on the IUCN Red List as endangered species (EN) or vulnerable species (VU); one species, S. lucifugus, is extinct.
Thermosphaeroma is a genus of crustacean in family Sphaeromatidae. They occur exclusively in hot springs of southwestern United States and central Mexico.
Clupeonella muhlisi is a species of clupeid fish endemic to Lake Uluabat in Turkey, linked to the Sea of Marmara.
Artemia monica, the Mono Lake brine shrimp, is a species of brine shrimp, endemic to Mono Lake in California, United States.
Coregonus lutokka is a putative species of whitefish in the genus Coregonus. It is native to Lake Onega and Lake Ladoga in Karelia, but it has been introduced to many other water bodies in Russia. It eats benthic larvae, molluscs and crustaceans, but in the summer it usually switches to feed on zooplankton.
