These creatures are considered cephalopods.  The animals found in the Class Cephalopoda are wildly intelligent organisms and vary greatly from the rest of the Phylum Mollusca, which include the minute gem and the suave liptooth.  To learn more about the classification of the H. lunulata click here!
