Concept

Problem: We are somewhat flattened and our dorsal surface is convex and covered with 8 articulating plates. We occur on rocky surfaces in the intertidal regions and our radula scrapes algae off the rocks. Our mantle forms a girdle around the margin of our plates and on each side of the foot is a row of gills suspended from the roof of the mantle cavity. Which of the following has our correct taxonomy?A. Phylum Mollusca, Class GastropodaB. Phylum Nematoda, Class BivalviaC. Phylum Mollusca, Class PolyplacophoraD. Phylum Mollusca, Class Bivalvia
