Paryphanta busbyi is a species of large predatory land snail, a terrestrial pulmonate gastropod mollusk in the family Rhytididae.
Beddomeia camensis is a species of very small freshwater snail that is endemic to Australia. The invertebrate is 2-4 mm in size, it is a gastropod mollusk and belongs to the Hydrobiidae family, a large family of freshwater snails recognised by their small size and cosmopolitan distribution. Beddomeia camensis is one of the least populated species within its family distributed across only 5 small to medium-sized streams that flow into the Cam River catchment in North-West Tasmania.
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.
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 snail in the family Tateidae. It is a very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusk. This species is endemic to Tasmania.
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.
