Abstract
The complete nucleotide sequence of the mitochondrial genome of long-finned squid Loligo edulis forma kensaki (L. edulis f. kensaki, Teuthida: Myopsida) was determined. It contains 13 protein-coding genes, 12SrRNA, 16SrRNA, and the 22 tRNA genes, and three long noncoding regions. We also determined the mitochondrial genome nucleotide sequence of seasonal brood samples of L. edulis f. budo collected from the western part of the Sea of Japan in the autumn to winter seasons, which showed morphologic discrepancies with L. edulis f. kensaki. Comparison of the two complete sets of mitochondrial DNA data showed that the similarity of the two sequences was as high as 99.9 %, with only eight nucleotide substitutions in coding regions. The complete mitochondrial genome of Loligo edulis f. kensaki from Nagasaki Pref. is 17360 bp and L. edulis f. budo from the Shimane Pref. is 17351 bp. The nucleotide sequences and haplotype patterns in ND1 suggest that L. edulis f. kensaki and L. edulis f. budo share a single genetic background.
