Pronunciation: [pˈaluːdˌɪnə] (IPA) 
The word "Paludina" is spelled with four syllables and pronounced pə-ˈlu-də-nə. The first syllable is unstressed and pronounced as "pə". The second syllable is stressed and pronounced with a short "u" sound, "ˈlu", followed by a "d" sound for the third syllable, "də". The final syllable is unstressed and pronounced as "nə", similar to the word "na". "Paludina" refers to a genus of freshwater snails, found throughout the world.
Paludina is a noun that refers to a genus of small, freshwater snails classified under the family Viviparidae. It is known for its spiral-shaped shell, which typically exhibits a conical or elongated shape. These snails are found in various aquatic habitats, such as rivers, lakes, ponds, and marshes, spanning different continents, including Europe, North America, and Asia.
The size of Paludina species can vary, but they generally range from a few millimeters to several centimeters in length. These snails possess a strong operculum, a protective plate that covers the shell opening when the snail retreats into its shell. They also have a muscular foot that enables slow locomotion and helps in burrowing into soft mud or sand.
Paludina snails are herbivorous organisms, primarily feeding on algae and detritus, thereby playing an essential role in the nutrient cycling within their ecosystems. They have a unique reproductive strategy called viviparity, wherein the female carries the developing embryos within her shell and gives birth to live young. This distinguishes them from most other snails, which typically lay eggs.
The presence of Paludina snails in freshwater environments serves as an indicator of water quality, as certain species are sensitive to poor water conditions or pollution. Their shells, often fossilized over time, provide valuable insights into paleontological studies, helping scientists understand past environments and evolutionary patterns.
Overall, Paludina is a diverse and ecologically significant genus of freshwater snails, contributing to the balance and health of freshwater ecosystems while serving as indicators of environmental conditions.
In geol., the marsh or river snail, inhabiting a top-shaped shell or whorl.

The word "Paludina" is derived from Latin. It comes from the word "palus" which means "swamp" or "marsh". The suffix "-ina" is a diminutive form used to indicate a smaller or less significant version. Therefore, "Paludina" can be translated as "little swamp" or "small marsh".
