Iglica gratulabunda is a species of very small freshwater snail with a gill and an operculum, an aquatic gastropod mollusk in the family Hydrobiidae. This species is endemic to Austria. It is probably found in subterranean freshwater habitat, but is known only from floodline debris. [1]
Heosemys is a genus of freshwater turtles in the family Geoemydidae. The genus Heosemys was split out of the related genus Geoemyda by McDowell in 1964.
The freshwater butterflyfish or African butterflyfish, Pantodon buchholzi, is the only species in the family Pantodontidae within the order Osteoglossiformes. It is not closely related to saltwater butterflyfishes.
The blue crayfish, sometimes called the electric blue crayfish, the sapphire crayfish, or the Florida crayfish, is a species of freshwater crayfish endemic to Florida in the United States. Its natural range is the area east of St. Johns River and all of Florida from Levy County and Marion County southwards, as well as on some of the Florida Keys. It is included on the IUCN Red List as a species of Least Concern. The blue crayfish is frequently kept in freshwater aquaria. In the wild, this species varies from brown-tan to blue, but the aquarium strain has been selectively bred to achieve a brilliant cobalt blue color.
Coregonus confusus is a freshwater whitefish from Switzerland. It is also known by its native Swiss German common name, spelled pfärrit, pfarrig, and pfärrig. It was described as Coregonus annectens confusus by Victor Fatio in 1885 from syntypes which have been lost in 1902. The species is rare and only known with certainty from Lake Biel. There is also a possibility that it might occur in Lake Neuchâtel. It vanished from Lake Murten in the 1960s due to eutrophication and water level management.
The painted terrapin, painted batagur, or saw-jawed turtle is a species of turtles in the family Geoemydidae. It was formerly in its own genus, Callagur, but has been reclassified to the genus, Batagur.
The East African black mud turtle, also known as the Pan terrapin, is a species of turtle in the family Pelomedusidae, native to eastern and southeastern Africa.
The Hispaniolan slider or Haitian slider is a species of turtle in the family Emydidae found on the island of Hispaniola.
The humpback whitefish, also referred to as the bottom whitefish, the Arctic whitefish or the pidschian, is a species of freshwater whitefish with a northern distribution. It is one of the members in the broader common whitefish complex, or the Coregonus clupeaformis complex. This fish lives in estuaries and brackish water near river mouths, in deltas and in slowly running rivers, in large lakes with tributaries, and floodplain lakes. It can migrate long distances upriver for spawning.
Coregonus trybomi is a freshwater whitefish in the family Salmonidae. It is a spring-spawning type of cisco, which probably has evolved from sympatric vendace independently in a number of Swedish lakes. Only one of those populations survives, and it is therefore considered Critically Endangered by the IUCN Red List. The status of Coregonus trybomi as a distinct species is however questionable. By Swedish authorities it is treated as a morphotype or ecotype, not an independent species. It was listed as "Data Deficient" in 2010 but excluded from the national red list in 2015.
Iglica kleinzellensis is a species of very small or minute freshwater snail with an operculum, an aquatic gastropod mollusk in the family Hydrobiidae. This species is endemic to Austria.
Pseudospatha tanganyicensis a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. It is the only species in the genus Pseudospatha.
Eels are ray-finned fish belonging to the order Anguilliformes, which consists of eight suborders, 19 families, 111 genera, and about 800 species. Eels undergo considerable development from the early larval stage to the eventual adult stage, and most are predators.
Moitessieriidae is a family of small freshwater snails, aquatic gastropod molluscs in the superfamily Truncatelloidea.
Iglica is a genus of very small freshwater snails with an operculum, aquatic gastropod mollusks in the family Moitessieriidae.
Iglica soussensis is a species of aquatic subterranean hydrobiid gastropod endemic to wells in the Souss Plain, Morocco. I. soussensis is only known from the type locality, a well in the Ait Msia village in the area of Agadir, or described by the IUCN as 'a well at Tamait Izder south of the Souss River north of Temsia, Morocco'. This species is a stygobiont, being restricted to aquatic subterranean habitats
