This study was investigated to statolith morphology, and examined applicability of the morphology to taxonomy the six Korean cephalopod species. The cephalopods used in the study were caught on the southern coast of Korea, and after transfer to the laboratory, statolith was extracted and observed. Observation results showed that the component parts of statolith were different between Octopoda and Decapoda consequently, it was possible to distinguish between Octopoda and Decapoda based on the statolith morphology. In Octopoda, the shape and location of the tip of the wing could be used as the taxonomic character. In Decapoda, Lateral dome and dorsal dome could be used for the taxonomic character. These morphological differences of statoliths are thought to be related to the ecology of each species.
