利用细胞色素氧化酶I （COI）和细胞色素氧化酶III （COIII）线粒体基因的部分核苷酸序列及其编码的氨基酸序列，研究了日本海域采集的7种深海巨蛤（双壳纲：蛤科）的系统发育关系。这7个物种分别是。soyoae(外相模湾),C。fausta(骏河湾),C。kaikoi(南开槽),C。nautilei(南开槽),C。phaseoliformis(日本海沟),C。南恩西山，冲绳海槽)和天竺葵。（Iheya Ridge， Okinawa海槽）。在一组三种（C. kaikoi， C. phaseoliformisandC.）之间观察到明显的系统发育分裂。福斯塔)和其他物种。这种聚类对应于之前描述的calyptogena属（calyptogena和ectenagena）中的两个亚属，c的位置除外。鹦鹉螺，它已被置于蜈蚣亚属。c的两个单倍型之间的遗传距离。COI区和COIII区分别为0.043和0.055，COIII区有3个氨基酸取代。来自Iheya Ridge的基因可以与c的两个单倍型（A型）之一区分开来。大豆只有一个核苷酸的替换，这一结果表明calyptogenasp。Iheya岭的一部分从mc中分离出来。在两个单倍型分化之后，现在从c中分离出来。soyoaein相模湾。
Phylogenetic relationships among the seven species of deep-sea giant clamsCalyptogena(Bivalvia: Vesicomyidae) collected around Japan were examined using parts of nucleotide sequences of mitochondrial genes for cytochrome oxidase I (COI) and cytochrome oxidase III (COIII) and the encoded amino acid sequences. The seven species wereC. soyoae(Sagami Bay),C. fausta(Suruga Bay),C. kaikoi(Nankai Trough),C. nautilei(Nankai Trough),C. phaseoliformis(Japan Trench),C. solidissima(Minami-Ensei Knoll, Okinawa Trough) andCalyptogenasp. (Iheya Ridge, Okinawa Trough). A clear phylogenetic split was observed between one group of three species (C. kaikoi, C. phaseoliformisandC. fausta) and the remaining species. This clustering corresponds to the two previously described subgenera within the genusCalyptogena (CalyptogeanandEctenagena) with the exception of the placement ofC. nautilei, which had been placed in the subgenusEctenagena. Genetic distances between two haplotypes ofC. soyoaewere 0.043 for the COI region and 0.055 for the COIII region, and three amino acid substitutions were detected with the COIII region.Calyptogenasp. from the Iheya Ridge could be distinguished from one of the two haplotypes (type A) ofC. soyoaeby only a single nucleotide substitution, a result that suggests thatCalyptogenasp. of the Iheya Ridge diverged fromC. soyoaeafter the two haplotypes had diverged, and it is now isolated fromC. soyoaein Sagami Bay.
