In this macro picture you can see a common limpet (Patella vulgata) covered with barnacles (Semibalanus balanoides) at low tide. The limpets are snails that feed on algae living on hard rock and stones. They are able adhere themselves strongly to hard surfaces and can be very hard to peel off if they sense danger.
I have been watching some TV-shows by the survivalist Ray Mears where he use a stick to whack them off using the surprise factor. I will have to try to cook some limpets later this year and I will report back here on how they taste 😉
If you look in the background you can see another limpet waiting for the tide to come back in.
The barnacles (Semibalanus balanoides) seem to get a free ride with the limpet, but I’m guessing the limpet is glad for having some extra camouflage.
Check out this photo of the shell of a limpet filled with small pieces of sand. The inside have some beautiful structures and colors.
