Limpets on a rock
7. Limpet
If you spy a conical shell about the size of a quarter, it’s probably a limpet. Limpets can usually be found affixed to the sides of rocks, but unlike barnacles, they are not stationary. They’re actually a type of marine snail.
Why they’re cool: Limpets have a strong muscular foot that holds them to the rocks. In fact, the foot is so strong that limpets are able to create a seal against the rock to hold in moisture. This keeps them from drying out in the sun while the tide is out. It also keeps them safe from predators that may try to pry them off.
