iridella

Iridella is a genus of freshwater snails belonging to the family Lymnaeidae, commonly known as pond snails. These aquatic gastropods are found in North America, inhabiting a variety of freshwater environments such as ponds, lakes, and slow-moving streams. The shells of Iridella snails are typically thin and dextral, meaning they coil in a clockwise direction. Their shape can vary between species but often exhibits a conical or ovate form with prominent whorls.

The snails themselves possess a soft, unsegmented body that can retract into the shell. They are herbivores, feeding primarily on algae and decaying plant matter found in their aquatic habitats. Iridella snails play a role in their ecosystem as detritivores, contributing to nutrient cycling. Like other Lymnaeidae, they are hermaphroditic, possessing both male and female reproductive organs, which can facilitate reproduction.

While generally not of significant economic importance, Iridella species are part of the broader biodiversity of freshwater invertebrates. Their presence and abundance can serve as indicators of water quality in their environment, as they are sensitive to pollution and habitat degradation. Research into Iridella often focuses on their ecological roles, reproductive strategies, and evolutionary relationships within the Lymnaeidae family.
