RÉSUMÉ
In this study, we determined the complete mitochondrial genome of the Loligo opalescence. The genome was 17,370 bp in length and contained 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 3 main non-coding regions. The composition and order of genes, were similar to most other invertebrates. The overall base composition of L. opalescence is A 38.62%, C 19.40%, T 32.37% and G 9.61%, with a highly A + T bias of 70.99%. All of the three control regions (CR) contain termination-associated sequences and conserved sequence blocks. This mitogenome sequence data would play an important role in the investigation of phylogenetic relationship, taxonomic resolution and phylogeography of the Loliginidae.

In this study, we determined the complete mitochondrial genome of the little squid (Loligo duvaucelii). The genome is 17,413 bp in length, containing 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 3 main non-coding regions. The overall base composition of L. duvaucelii is 40.01% A, 32.33% T, 19.14% C and 8.52% G, with a high A + T bias of 72.34%. All of the three control regions (CR) contain termination-associated sequences and conserved sequence blocks. Here, we describe a phylogenetic analysis of 10 species of Cephalopoda based on the complete mitochondrial genome, the result showed that the Loliolus uyii is most closely related to L. duvaucelii. This mitogenome sequence data would play an important role in the investigation of phylogenetic relationship, taxonomic resolution and phylogeography of the Cephalopoda.
