The freshwater snail is a type of mollusk that lives in rivers, lakes, and ponds. These snails have soft bodies and hard shells, which can vary in shape and color. They play an important role in their ecosystems by helping to break down organic material and serving as food for various animals, including fish and birds. Freshwater snails breathe through a specialized structure called a lung or gill, depending on the species. They are often found in shallow waters and can be seen gliding along surfaces using a muscular foot. Some species, like the Apple snail, are popular in aquariums due to their unique appearance and behavior.
