Gastropod

Gastropods are a class of molluscs characterized by their coiled shells, although some members, such as slugs, lack an external shell. They are one of the most diverse and widespread groups of animals within the mollusc taxon, and can be found in terrestrial, freshwater, and marine environments.
The foot of gastropods is a muscular structure used for crawling and, in some cases, swimming. It is the primary means of locomotion for these animals. The foot is located beneath the body and extends from the head to the tail. Gastropods possess a specialized feeding organ called a radula, a ribbon-like structure covered in rows of tiny, chitinous teeth. They use the radula to scrape and feed on various food sources, such as algae, plants, detritus, or other small organisms.
Many gastropods, known as snails, have coiled, spiral-shaped shells. The coiling can be dextral (right-coiled) or sinistral (left-coiled), depending on the species. The shells are typically made of calcium carbonate and serve to protect the soft body of the gastropod. Gastropods who lack this shell are known as slugs.
