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.

Since the discovery of deep-sea hydrothermal vent communities in 1977, researchers have made efforts to understand the mechanisms underlying the biodiversity of these communities. “Biodiversity” is hierarchical in nature, ranging from genetic to ecosystem levels and local to regional scales, and encompassing genetic, species, ecosystem, and landscape diversity. A previous paper suggested that interactions between local and regional ecological processes in hydrothermal vent ecosystems could be understood through a metacommunity framework. As a first step toward understanding the complex interactions in these ecosystems, summarizing evolutionary-ecology studies conducted at different hierarchical levels for each vent taxon could be useful. Barnacles are suitable model species for studying evolutionary ecology at various spatiotemporal scales because of the good availability of fossil records, and because of their wide distribution and high potential for laboratory/field-based experiments using both larvae and adults. In this paper, studies on hydrothermal vent barnacles at each hierarchical level of biodiversity are reviewed.
