Beddomeia protuberata facts for kids
Beddomeia protuberata is a special kind of freshwater snail. It lives only in northern Tasmania, Australia. This snail is quite rare! Scientists named it in 1993.
What Does This Snail Look Like?
The shell of Beddomeia protuberata is shaped like an oval. It has a yellowish outer layer. This layer can have small bumps on it. These snails are very small. They are usually between 2.29 mm and 2.93 mm long. Their width is between 2.01 mm and 2.34 mm.
The snail's shell has parts called whorls, which are like spirals. The first part of the shell, called the protoconch, has about 1.75 turns. The main part of the shell, called the teleoconch, has 2.2 to 2.7 rounded turns. The shell's surface has faint lines. These lines show how the shell grew over time.
The opening of the shell is evenly circular. The inner edge of the opening is medium-sized. The outer edge leans forward a bit. This is called prosocline. The snail also has a small opening called an umbilicus. Its width is between 0.31 mm and 0.51 mm. Female snails usually have a wider umbilicus than male snails.
Where Does This Snail Live?
The Beddomeia protuberata snail group is found only in Tasmania. Many things affect where these snails can live. These include the local rocks and the water conditions. For example, how much rain falls and what chemicals are in the water are important. Things that humans do also affect where these snails can be found.
Because of these reasons, Beddomeia protuberata is a very rare species in Australia. It is listed as a rare species under the Threatened Species Protection Act (1995). This law helps protect animals and plants that are in danger.
