A limpet is an aquatic snail with a shell that is broadly conical in shape.
Limpets use a tongue bristling with tiny teeth to scrape food off rocks and into their mouths, often swallowing particles of rock in the process. Engineers in the UK have found that limpets' teeth consist of the strongest biological material ever tested. |

Another interesting thing about them is that when threatened, a limpet can run away at a speed of two inches (2cm) an hour.
