The chiton (Polyplacophora) occupies a significant position in molluscan evolutionary history as one of the most primitive groups within the phylum Mollusca. (Tapparone-Canefri 1874) (Chitonida: Acanthochitonidae) is a commonly found intertidal chiton species in South Korea. In this study, we characterized the complete mitochondrial genome of (14,999 bp long), comprising 13 protein-coding genes (PCGs), 22 transfer RNA genes, two ribosomal RNA genes, and an A + T rich region (166 bp). The base composition is as follows: 31.82% for A, 11.63% for C, 16.69% for G, and 39.86% for T. We reconstructed a maximum likelihood (ML) tree to elucidate phylogenetic relationships among the eight chitonid families using the nucleotide sequences of all PCGs. The ML tree revealed that clustered with (BP 100) within the family Acanthochitonidae. Acanthochitonidae formed a sister group with Mopaliidae. The results could provide a valuable understanding the phylogenetic relationships of chitonid species.
石鳖（多板纲）作为软体动物门中最原始的类群之一，在软体动物进化史上占据重要地位。（塔帕罗内 - 卡内弗里，1874年）（石鳖目：棘石鳖科）是韩国常见的潮间带石鳖物种。在本研究中，我们对[具体石鳖物种]的完整线粒体基因组进行了特征分析（长度为14,999 bp），其包含13个蛋白质编码基因（PCGs）、22个转运RNA基因、两个核糖体RNA基因以及一个富含A + T的区域（166 bp）。碱基组成如下：A占31.82%，C占11.63%，G占16.69%，T占39.86%。我们使用所有PCGs的核苷酸序列重建了一个最大似然（ML）树，以阐明八个石鳖科之间的系统发育关系。ML树显示，[具体石鳖物种]在棘石鳖科内与[另一石鳖物种]聚类（BP值为100）。棘石鳖科与毛石鳖科形成姐妹群。这些结果可为了解石鳖物种的系统发育关系提供有价值的信息。
