Limpets are hardy survivors on the rocky shore and are commonly seen clinging tightly to rocks at low tide. Limpets have a soft body underneath the hat-shaped shell and they graze algae by scraping it with their radula - a tongue-like structure covered in teeth. Limpets always return to the same spot on the rocks and eventually wear a groove in the rocks that fits their shell exactly.
