I often think about what I would like to come back as in the next life, and also what I definitely wouldn't want to come back as; the limpet falls into the latter category. Can you image living for up to twenty years, being battered by the stormy seas, or baked by the sun, living on hard abrasive rocks, with nothing to do but eat? It certainly isn't a life that would appeal to me!
If any marine experts are reading this I would be interested to know if both of these are Patella vulgata or whether the peach coloured one is something else? Or perhaps neither are Patella vulgata? I am not that knowledgeable on sea creatures. (Hanging my head in shame as I should be living next to the sea!)
