About Common Limpet
Common Limpets live on exposed coastal rocks, where they are battered by the force of the ocean waves. Their shells are cone shaped instead of coiled, which makes them very strong. At low tide, they clamp their shells tightly to rocks. At high tide, they loosen their tight hold and wander over the surface of the rocks to feed. They will travel up to 3 ft. (1m) from their starting place. Using their very tiny teeth, they scrape away tiny seaweed and other algae. When the tide goes out, they will return to the exact same spot from where they started.
