Seven families are currently recognised within the order, including the well-known ark clams or ark shells in family Arcidae.
Scientific classification or biological classification is a method by which biologists group and categorize species of organisms. Scientific classification also can be called scientific taxonomy, but should be distinguished from folk taxonomy, which lacks scientific basis.
