Beddomeia is a genus of very small freshwater snails that have a gill and an operculum, aquatic operculate gastropod mollusks in the family Tateidae.
Species within the genus Beddomeia include: [2]
Anceya is a genus of tropical freshwater snails with an operculum, aquatic gastropod mollusks in the family Paludomidae.
Beddomeia averni is a species of very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusk in the family Hydrobiidae. This species is endemic to Australia. The Hydrobiidae snail has been categorized into four distinct groups: Beddomeia being one of them. Very little is known about their ecology and habitat. Low funding in Australia for the conservation of threatened species is partly responsible for this; moreover, there are only a few good sources that contribute to its limited data required to have a better understanding. Studies have shown that it is hard to distinguish the species from a morphology point of view. A non-taxonomist may find it arduous to tell differences among different members of the species. Therefore the anatomical study is incorporated to understand and differentiate them. It is found that human-led actions such as agriculture, forestry, mining, etc have caused major degradation in their population. Other factors such as changes in water conditions due to sedimentation, varying temperature, mineral level, salinity can either positively/negatively impact their population
Beddomeia bellii is a species of very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusc in the family Hydrobiidae. This species is endemic to Australia.
Beddomeia capensis is an aquatic operculate gastropod mollusk, a species of very small freshwater snail that has a gill and an operculum, in the family Hydrobiidae. The species is classified as endangered and known to be endemic to five streams within a relatively small area on the island state of Tasmania, Australia. However, recent surveys have only been able to locate Beddomeia capensis in two small streams on Table Cape, with the total length of inhabited stream less than 80 metres (260 ft).
Beddomeia fultoni(B. fultoni) is a species of small freshwater snail belonging to the family Tateidae.
Beddomeia hullii is a species of very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusc in the family Hydrobiidae. This species is endemic to Australia.
Beddomeia launcestonensis is a species of very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusk in the family Hydrobiidae. This species is endemic to Australia.
Beddomeia lodderae is a species of very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusc in the family Hydrobiidae. This species is endemic to Australia.
The Beddomeia minima is a population of freshwater snails that are endemic to Australia. It is commonly called a hydrobiid snail. This population was listed as Vulnerable on the IUCN Red List in 2011 due to its distribution being restricted to a single location and range of possible threats present in Tasmania. The Beddomeia minima is one of a few fresh water snail species belonging to the same genus Beddomeia that survive in Tasmania, Australia, specifically a single location in the Scottsdale area.
Beddomeia phasianella is a species of very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusk in the family Hydrobiidae. This species is endemic to Australia.
Beddomeia protuberata is a species of endemic freshwater snails living in north-western Tasmania, Australia. The shells look ovate and periostracum yellow with some pustules, length between 2.29 mm and 2.93 mm and width between 2.01 mm and 2.34 mm. Beddomeia protuberata has 1.75 protoconch whorls. Its image of microsculpture is uniform and its wrinkles arranged weakly and helically. The teleoconch of beddomeia protuberata has 2.2 to 2.7 convex whorls, and the ratio of convexity is 0.15 to 0.24. Sculptures of the teleoconch are vague with prosocline growth lines. The margin of the last whorl is evenly circular. The thickness and width of inner lips are medium sizes, and the columellar swelled up prominently. The outer lips of beddomeia protuberata is prosocline, which means the shell leans forwards compared to the shell’s coiling axis. The width of their umbilicus is between 0.31 mm to 0.51 mm. The umbilicus of female beddomeia protuberata are wider than the umbilicus of male.
Beddomeia trochiformis is a species of very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusk in the family Hydrobiidae. This species is endemic to Australia.
Beddomeia tumida is a species of very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusc in the family Hydrobiidae. This species is endemic to Australia.
Beddomeia waterhouseae, also known as Claytons Rivulet freshwater snail, is a species of freshwater snail in the family Tateidae. This species is endemic to northern Tasmania in Australia. The holotype specimen was found in a very small tributary of Little Clayton's Rivulet and is held at the Australian Museum. B. waterhouseae is small and as an adult has a shell measuring between 1.7 to 3.7 mm in length. The shell shape is ovate-conic to broadly conic and has a thin inner lip and no columellar bulge. This species feeds on algae and detritus on rocks. The female of the species lay single eggs in capsules made of sand grains and attached to the underside of rocks or wood. B. waterhouseae is considered vulnerable by the IUCN as it has a very small range and is sensitive to water quality and so may be threatened by disturbances of its habitat. Other threats include habitat loss. Conservation activities such as assessment of the aquatic ecosystem and vegetal surveys are being undertaken in an attempt to preserve this species.
Cleopatra ferruginea is a species of freshwater snails with an operculum, aquatic gastropod molluscs in the family Paludomidae.
Erinna is a genus of air-breathing, freshwater snails, aquatic pulmonate gastropod mollusks in the family Lymnaeidae, the pond snails. This genus is endemic to the Hawaiian Islands, United States.
Austropyrgus is a genus of minute freshwater snails with an operculum, aquatic gastropod molluscs or micromolluscs in the Hydrobiidae family. Austropyrgus species are endemic to Australia, where they are found in virtually all freshwater habitats, from high mountain streams to isolated springs in the arid zone.
Austropyrgus smithii is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the Hydrobiidae family. This species is endemic to western Tasmania, Australia, and is found in a number of small rivers and streams.
Tateidae is a family of very small and minute aquatic snails with an operculum, gastropod mollusks in the superfamily Truncatelloidea.
