Marine gastropods are a diverse group of mollusks that primarily inhabit ocean environments. They are characterized by their soft bodies, which are often protected by a single, spiraled shell. Common examples include snails and slugs, which can be found in various marine habitats, from coral reefs to deep-sea environments. These creatures are known for their unique feeding mechanisms, often using a specialized structure called a radula to scrape food from surfaces. Marine gastropods play essential roles in their ecosystems, contributing to nutrient cycling and serving as food for various predators, including fish and sea birds.
