This study compared three phylogenetic trees based on 34 complete mitochondrial genomes, including Amphibalanus eburneus, Fistulobalanus kondakovi, and Megabalanus rosa, in terms of (1) gene order, (2) concatenated protein-coding genes, and (3) universal cytochrome c oxidase subunit I (COX1) marker regions. Each phylogenetic tree exhibited significant topological differences (Robinson-Foulds distance of 0.55-0.92). The protein-coding genes (78.8%) performed significantly better in terms of monophyletic preservation than the COX1 marker region (61.3%) and gene order (50.0%). Gene order analysis identified two genomic regions (I and II) as hotspots (regions with concentrated rearrangement activity) with significantly elevated breakpoint densities (319 and 100 breakpoints, respectively; p < 0.001), indicating concentrated genome rearrangement activity. Although all three methods consistently preserved some families, they strongly suggested that taxonomic re-evaluation is necessary for Balanidae. In conclusion, gene order provides insights into genome evolution patterns, concatenated protein-coding genes are the most suitable for phylogenetic studies, and COX1 markers are useful for rapid species identification rather than phylogenic classification.
