Common Limpet

The common limpet is a small sea snail that clings tightly to rocks along Europe's western coasts. Its cone-shaped shell helps it withstand crashing waves while it grazes on algae. These mollusks are so sturdy that some return to the exact same spot on the rock after feeding.

• Uses a muscular foot to clamp onto rocks with surprising strength.
• Scrapes algae off rocks using a tongue-like structure called a radula.
• Breathes through gills hidden beneath its protective shell.
