Beddomeia is a genus of very small freshwater snails that have a gill and an operculum, aquatic operculate gastropod mollusks in the family Tateidae.
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 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 hallae, also known as Buttons Rivulet hydrobiid snail, is a species of small freshwater snail that is endemic to Australia. The species is an aquatic operculate gastropod mollusk in the family Hydrobiidae. Beddomeia hallae belongs to the genus Beddomeia, which is the largest group in the family Hydrobiidae, consisting of 47 species. In the Threatened Species Protection Act 1995, this species is one of the 37 Beddomeia species listed as endangered, however, on the International Union for Conservation of Nature Red List, the species is listed as vulnerable. Found in Tasmania, in the streams of Buttons Rivulet and Castra Rivulet, Beddomeia hallae is sighted in its natural habitat amongst wood, leaves and under stones. Nonetheless, the Beddomeia species including Beddomeia hallae are geographically isolated, existing within restricted ranges.
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 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 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.
Beddomeia zeehanensis is a species of very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusk in the family Hydrobiidae. The species was first described in 1993 by Winston Ponder and G.A. Clark.
