Limpet
The little conical hats stuck to every tide-zone rock. Limpets are grazing sea snails with a single simple shell and a grip so strong you cannot pry one off if it senses you coming. Small but edible, and a survival-forager's reliable snack off the rocks.
Identifying
- a single low cone of shell, ribbed, grey-brown, blending into the rock
- a broad muscular foot underneath clamps down with astonishing suction
- grazes algae in a slow circle and returns to the exact same "home scar" on its rock
- distinct from a barnacle (which is cemented shut) — a limpet can lift and crawl
Facts
- their teeth are made of the strongest natural material known, a goethite-fiber composite stronger than spider silk
- each limpet keeps a home base ground into the rock and navigates back to it every low tide
- pop them off fast before they clamp, then grill or add to a seafood boil
