This paper focuses on the arm formula of Sepia esculenta and its application in taxonomy. The investigation results showed that there were many types of arm formulas in Sepia esculenta. Duncan multiple comparison indicated that the arm formula of Sepia esculenta was different in individual, size, left and right and sex. When all the arm formulas are same in all samples, including the left and right sides of male and female, the arm formula could be actual for the species. At the mention of the arm formula of Sepia esculenta, there should be some propositions such as sex, left and right, size, etc. It is suggested that the arm formula should be used carefully in the study of Sepia esculenta.
