Lenticulidae

Lenticulidae is a family of freshwater snails, commonly known as bladder snails. These gastropod mollusks are characterized by their thin, translucent shells, which are typically coiled in a sinistral (left-handed) direction. The family is widespread and found in a variety of aquatic habitats, including ponds, lakes, slow-moving streams, and even temporary puddles. Lenticulidae are detritivores, feeding primarily on decaying organic matter, algae, and diatoms. They play an important role in aquatic ecosystems as decomposers.

The reproductive strategy of Lenticulidae is notable for their hermaphroditism; each individual possesses both male and female reproductive organs. They typically reproduce by cross-fertilization, although self-fertilization is also possible under certain conditions. Their life cycle is relatively short, with rapid reproduction rates, contributing to their common presence in many freshwater environments. Some species within Lenticulidae have been introduced to regions outside their native range and can sometimes be considered invasive, potentially impacting native snail populations or acting as intermediate hosts for parasites. Despite this, many species are harmless and are frequently used in laboratory research due to their ease of breeding and study.
