Thanks so much Neil. I was lucky to find this one moving around on a rock edge. Their ability to leave a position and come back to the same place by using their sencors is remarkable. Tongue Point is one of those rare places that reveals something new everytime you go there.

Back at your favourite spot, Brian? I love this area with its beautiful wildlife, and your amazing spotting. This one is awesome and I am flabbergasted!! I have never seen a limpet from this perspective.
