Phylogenetic relationship among three species of deep-sea vesicomyid bivalves
Calyptogena, i.e., C. soyoae, C. solidissima, C. fausta and an undescribed species of the Iheya Ridge, Okinawa Trough was analyzed on the basis of the RFLP analysis of the fragment (about 1 kbp) of cytochrome oxidase I. Both the two populations of C. soyoae (off Hatsushima and Okinoyama Bank, Sagami Bay) consisted of two haplotypes, which could be discriminated by only one restriction site (1.7% sequence divergence). Calyptogena of the Iheya Ridge could not be distinguished from one of the two haplotypes of C. soyoae. Nucleotide substitution rates between species were calculated and dendrograms were constructed.
