Barnacle. ID ?? Guess at Balanus genus. Unusually large, flat species which I'm struggling to identify. Almost the size of an adult Cellana radians limpet but even lower profile with quite small parieties compared to the diameter of the shell structure. Initially on turning the cobble it looked to be a flat worm until given a prod and realisation it was a fixed hard encrustation dawned.

Not come across this shape before. 10mm long. Living in a shallow rock pool in the high intertidal zone
-
Not too sure which ones these are. Small, under 10mm and found under a rock in the low intertidal zone.
