Abstract
The complete mitochondrial genome of the Sepiella maindroni has been sequenced. The mitochondrial genome is 16 170 bp in length, containing 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes. The gene order and composition of S. maindroni mitochondrial genome was similar to that of most other invertebrates. The overall nucleotides base composition of the heavy strand is A (39.91%), G (8.06% of), C (16.52%), and T (35.50%), with highly A + T bias of 75.41%. Seen from the phylogenetic tree, S. maindroni, Sepiella japonica, and Sepiella inermis from the same genus (Sepiella) clustered into one branch.
