F+++. THE IMPRESSUM FORM IN IT’S BEST APPEARANCE. Corculum cardissa f. impressum is easy to recognize because of a ring of interrupted red flecks all around the periphery of the shell. This is one of the best, with deep wine red big spots all around and two major lines which extend much more than usual on the flat side of the shell. A beauty.
Philippines. Cebu. Olango Island. Dive in shallow water. November 2013.
