<p>In the submarine caves of the Ryukyu Islands, the existence of many non-described species has been indicated in field surveys. To estimate the magnitude of biodiversity in the submarine caves, application of genetic analyses would provide a promising approach. Genetic analysis by DNA barcoding based on mitochondrial cytochrome c oxidase subunit I (COI) is informative for the study of submarine caves because the data of COI region have been accumulated in many marine animals. Also, in order to understand the formation process of communities of submarine caves, population genetic approaches would be useful to evaluate the connectivity patterns among submarine caves which are not continuously distributed along the Ryukyu Islands. In addition, utilization of high-throughput sequencing technology (e.g., environmental DNA (eDNA) analysis) would be also powerful for the ecological studies of submarine caves of the Ryukyu Islands. We discuss the current situation of genetic analyses in the submarine caves of the Ryukyu Islands and propose the prospects of genetic analyses for future studies.</p>
