Characterization and phylogenetic analysis of the complete mitochondrial genome of <i>Aipysurus eydouxii</i> Gray 1849 (Elapidae: Hydrophiinae)

Hydrophiine sea snakes represent ecologically significant and species-rich marine predatory reptiles, many of which inhabit marine environments throughout their entire lifecycles. However, due to morphological variability and limited molecular phylogenetic studies, the taxonomic relationships within this group remain unclear. In this study, we present the first complete mitochondrial genome of Aipysurus sea snakes, specifically <i>Aipysurus eydouxii</i> Gray 1849. The mitogenome comprises 17,228 base pairs and contains a total of 37 genes, plus a putative control region. This study provides valuable genetic data that will contribute to the future taxonomic classification and ecological protection of hydrophiine sea snakes.
