Idaholanx fresti Clark, Campbell & Lydeard, 2017 [1] | |
Idaholanx fresti, the Banbury Springs limpet or Banbury Springs lanx, is a rare species of freshwater snail, an aquatic gastropod mollusc in the family Lymnaeidae. It is the only species in the genus Idaholanx. First discovered in 1988, the species was formally described and named in 2017. [1]
This freshwater limpet is endemic to the US State of Idaho, where it is known from a 10-kilometer stretch of the Snake River. It is found in four complexes of springs along the Snake River in south-central Idaho: Thousand Springs, Box Canyon Springs, Banbury Hot Springs, and Briggs Springs. [2]
This snail is cinnamon red in color. The shell is conical in shape. It is up to 7.1 millimeters long by 6 wide and up to 4.3 millimeters tall.
This snail is similar in its morphology to species in the genus Lanx , but genetic analysis reveals that it is genetically more similar to the genus Fisherola . [2]
Idaholanx fresti lives in fast flowing, clean, cold water springs. It needs highly oxygenated water. [3]
In 1992 it was federally listed as an endangered species of the United States. [4] This species is endemic to Idaho. It only exists at four places: Thousand Springs, Box Canyon Springs, Briggs Springs and Banbury Springs. It is threatened by habitat modification, spring flow reduction, groundwater quality, and invasive species. [5]
Dead plants and diatoms. [6]
The delta smelt is an endangered slender-bodied smelt, about 5 to 7 cm long, in the family Osmeridae. Endemic to the upper Sacramento-San Joaquin Estuary of California, it mainly inhabits the freshwater-saltwater mixing zone of the estuary, except during its spawning season, when it migrates upstream to fresh water following winter "first flush" flow events. It functions as an indicator species for the overall health of the Delta's ecosystem.
The Kanab ambersnail, formerly classified as Oxyloma haydeni kanabense or Oxyloma kanabense, is a small, air-breathing land snail belonging to the the family Succineidae, the ambersnails. This terrestrial pulmonate gastropod mollusc was previously considered a critically endangered subspecies or species. In 2013, a scientific investigations report by the United States Geological Survey concluded that the Kanab ambersnail is not a genetically distinct species. In June 2021, the Fish and Wildlife Service removed the Kanab ambersnail from the United States Fish and Wildlife Service list of endangered mammals and birds and classified it with other common ambersnails within the same taxa, officially negating its status as a distinct subspecies.
Lymnaeidae, common name the pond snails, is a taxonomic family of small to large air-breathing freshwater snails, aquatic pulmonate gastropod mollusks, that belong to the clade Hygrophila.

Assiminea pecos is a rare species of snail in the family Assimineidae known by the common name Pecos assiminea. It is native to New Mexico and Texas in the United States. Specimens known from Mexico are now treated as members of a separate species, Assiminea cienegensis. The Pecos assiminea was federally listed as an endangered species of the United States in 2005.

Lirceus usdagalun is a rare species of crustacean known by the common name Lee County cave isopod. It is endemic to Virginia in the United States, where it is known from a single network of karst cave systems in Lee County. It is threatened by a number of processes. It is a federally listed endangered species of the United States, and is assessed as "endangered" by the International Union for Conservation of Nature.
Lithophragma maximum, known by the common name San Clemente Island woodland star, is a rare species of flowering plant in the saxifrage family. It is endemic to San Clemente Island, one of the eight Channel Islands of California. It is known from only about four kilometers of rocky coastal cliffs on the edge of the island. The plant was thought to be extinct until a few specimens were rediscovered in 1979. Only 200 individuals were tallied in a 1996 survey. In 1997 the plant was listed as an endangered species on the federal level.
Gratiola amphiantha is a rare species of flowering plant known by the common names little amphianthus, pool sprite and snorkelwort. It was previously the only species in the monotypic genus Amphianthus, but it was moved to genus Gratiola after genetic analysis in 2008. It is native to the Piedmont region of the southeastern United States, with a center of distribution in Georgia. It occurs in Alabama and South Carolina as well. It is limited to granite outcrops, a high-biodiversity habitat type that is threatened by activities such as quarrying, off-road vehicles, and trash and debris dumping.
