Bagis

Bagis is a genus of small, freshwater snails belonging to the family Lymnaeidae. These snails are commonly known as ramshorn snails or pond snails, although this common name is also applied to other genera. Bagis snails are characterized by their coiled shells, which are typically flattened and spiraled in a single plane, resembling a ram's horn. The shell opening, or aperture, is usually large and rounded.

These snails are widespread in freshwater habitats across the globe, including ponds, lakes, streams, and marshes. They are often found attached to submerged vegetation or the substrate of the water body. Bagis snails are primarily herbivorous or detritivorous, feeding on algae, decaying plant matter, and other organic debris. They play a role in aquatic ecosystems by contributing to nutrient cycling and serving as a food source for various aquatic animals.

Reproduction in Bagis snails is typically sexual, with most species being hermaphroditic, possessing both male and female reproductive organs. They lay gelatinous egg masses on aquatic plants or other surfaces. The development of Bagis snails can vary depending on the species and environmental conditions. Some species are known to be invasive in certain regions, potentially impacting native aquatic communities.
