Small groups of this barnacle stood out amongst the others, though i know some species grow tall and more steep sided in dense colonies this didn't seem to be the case here, the most closely resembling species i can find is B.hameri(Chirona hameri). However, i am very dubious of this identification, especially on checking the NBN gateway distribution!
