A gastropod is a type of mollusk that includes creatures like snails and slugs. These animals are known for their soft bodies and often have a coiled shell, although some, like slugs, lack a shell entirely. Gastropods are found in various environments, from oceans to freshwater and even on land. They play important roles in ecosystems, often helping to break down organic matter. Gastropods move using a muscular foot, which allows them to glide smoothly over surfaces. They also have a unique feeding structure called a radula, which is like a tongue with tiny teeth that helps them scrape food off surfaces. This adaptability makes gastropods fascinating and diverse creatures in the animal kingdom.
