A snail is a small, soft-bodied creature that belongs to the class Gastropoda. They are known for their coiled shells, which provide protection from predators and harsh environments. Snails can be found in various habitats, including gardens, forests, and even underwater. They move slowly using a muscular foot and secrete mucus to help them glide over surfaces. Snails are primarily herbivores, feeding on plants, leaves, and decaying matter. They play an important role in the ecosystem by helping to break down organic material. Some species of snails can also be found in marine environments, contributing to the biodiversity of ocean ecosystems.
