Slow Crawlers is a term used to describe snails, which are small mollusks that have a soft body and a hard shell. They move slowly by using a muscular foot to push themselves along surfaces. Snails are found in a variety of habitats, from deserts to oceans, and they feed on algae, fungi, and decaying plant matter. They are an important part of the food chain, providing food for other animals such as birds, frogs, and lizards.
