Complete mitochondrial genome of the spineless cuttlefish Sepiella inermis (Sepioidea, Sepiidae)

Abstract

In this study, we determined the complete mitochondrial genome of the spineless cuttlefish Sepiella inermis. The genome was 16,191 bp in length and contained 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 2 main non-coding regions [both are control regions (CR)]. The composition and order of genes, for the mitogenome found in S. inermis were similar to most other invertebrates. The overall base composition of S. inermis is T 35.6%, C 16.4%, A 40.0% and G 8.0%, with a highly A + T bias of 75.6%. Two control regions contain both termination-associated sequences and conserved sequence blocks. Thus, mitogenome sequence data would play an important role in the investigation of phylogenetic relationship, taxonomic resolution and phylogeography of the Sepiidae.
