The complete mitochondrial genome of Sepia latimanus (Sepiidae, Sepioidea) and its phylogenetic implications

Abstract

We describe the complete mitochondrial genome of the broadclub cuttlefish Sepia latimanus, the second largest cuttlefish, collected from the coral waters of Naozhou Island in tropical South China. It is a circular molecule of 16,225 bp in size and consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and 1 control region in typical gene arrangement conforming to the vertebrate consensus. The complete mitochondrial genomic sequence of S. latimanus and other 8 species from the same Family Sepiidae were used for phylogenetic analysis and demonstrated that S. latimanus clustered with S. apama, the largest cuttlefish species, and made a separate clade, closely related to the other Sepia and Sepiella species in Family Sepiidae.
