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 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 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 krybetes is a species of very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusk in the family Tateidae. It was first described in 1993 by Winston Ponder, G.A. Clark, Alison Miller and A Toluzzi.
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 mesibovi is a species of very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusk in the family Tateidae. It was first described in 1993.
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 petterdi is a species of snail in in the family Tateidae. It is a very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusk. It was first described in 1993.
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 protuberata is a species of endemic freshwater snail in the family Tateidae, found in northern 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 salmonis is a species of very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusk. This species is endemic to Australia, and was first described in 1993 by Winston Ponder and G.A. Clark.
Beddomeia topsiae is a species of snail in the family Tateidae first described in 1993.
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.
Carnarvonchochlea exigua, more commonly known as Jardinella exigua is a small freshwater snail residing in North East Queensland, near Carnarvon Gorge. Carnarvoncochlea refers to the location of origin, whilst exigua derives from the latin word “exigus” meaning “small”.
Trochidrobia inflata is a species of very small freshwater snail, an aquatic gastropod mollusk in the family Tateidae. This species is endemic to Australia. Trochidrobia inflata derives the name inflata from the inflated shell of this species.
The Inglis River is a river in North West Tasmania, Australia, it extends approximately 61 kilometres (38 mi) from the Campbell Ranges near Takone before discharging into Bass Strait at Wynyard. The Flowerdale River is the largest tributary system on the Inglis River and makes up approximately one-third of the 471-square-kilometre (182 sq mi) Inglis-Flowerdale catchment basin.
Table Cape is a extinct volcano located near Wynyard on the North West of Tasmania, Australia, it is also the name of the locality which encompasses the geological feature. Table Cape is a more or less circular extinct volcano with a flat top, its northern and eastern faces rise steeply from Bass Strait to a height of approximately 170 metres (560 ft) above sea level. It was named by British navigator, Matthew Flinders, as he and George Bass circumnavigated Van Diemen's Land in 1798 upon the Norfolk. Flinders also progressively named the nearby Circular Head, Three Hummock and Hunter Islands.
