Turbo sazae, a commercially and ecologically significant marine gastropod traditionally found in Jeju Island the southern coast of Korea, is experiencing reported northward expansion into East Sea, likely influenced by rising seawater temperatures. This study provides preliminary genetic insights structure connectivity T. sazae populations between Sea using mitochondrial COI sequences. Samples from 6 geographically distinct locations were analyzed, with three cloned replicates generated to enhance sequence reliability. Genetic diversity, haplotype distribution, population differentiation then assessed. Our analysis reveals potential populations, possibly driven larval dispersal via Kuroshio Tsushima Currents, highlighted predominance shared EJ1 (60.0% Jeju, 50.0% Sea). Bayesian phylogenetic estimated time most recent common ancestor (MRCA) at approximately 9.7 23.3 million years ago, indicating ancient divergence rather than very separation. Pairwise FST values AMOVA results showed generally low levels differentiation. Given small sample sizes use single marker, these findings should be interpreted cautiously as evidence. Nevertheless, this highlights need for continued monitoring under climate-driven range shifts foundation future research incorporating broader genomic approaches.
