(a) A tragic sea accident several centuries ago drowned a young Samura As a tribute to his bravery, nature through.its inscrutable ways immortalized his face by imprinting it on the crab shells in that area. (b) After the sea tragedy,,fisherman in that area, in a gesture of honour of their dead hero, let free crab shell caught by them which accidentally hadj a shape resembling the face of a Samurai.
