Complete mitochondrial genome is sequenced from an opisthobranch gastropod Aplysia kurodai. Mitochondrial genome size of the species is 14,113 bp. The mitochondrial genome of A. kurodai contains 13 protein coding genes, two ribosomal RNA genes, and 22 tRNA genes like mitochondrial genomes of congeneric species. The gene order of protein coding genes is identical to that of other Aplysia species. A+T content (65.9%) of the mitochondrial genome is included in the range for A+T content of congeneric species. This genome data provides evolutionary and systematic implications for the related species.
