Marine snails are a diverse group of mollusks found in oceans around the world. They belong to the class Gastropoda and are characterized by their coiled shells, soft bodies, and muscular foot, which they use for movement. Marine snails play important roles in their ecosystems, often serving as grazers that feed on algae and detritus. These snails exhibit a wide range of sizes, colors, and shapes, with some species, like the Cone Snail, possessing venom that can be harmful to predators and humans. Marine snails reproduce by laying eggs, and their larvae often drift in the water before settling on the ocean floor.
